If you haven't read them, it's okay, because this is a 'prequel'. I have the place to myself, Andrea thought. At eighteen, she lived at home with her parents, her big sister Donna, and Jack, who was two years older than Andrea. Their parents both worked second shift jobs; Donna was commuting to nursing school, and Jack managed a franchised tune-up place. Andrea decided to do one of her favorite activities: watch one of her parents dirty movies and masturbate. Being home alone meant that she could use the big screen TV in the living room. Of course, it wasn't real porn. It was a collection of those late night cable erotic story anthologies. She selected one of her favorites, the one where an older man seduces a sweet young girl. She would watch it, replacing the girl with herself. But lately, she started imagining her brother as the older man. It was wrong, and she knew it. But she also knew that he was pretty hot. She thought about his 5' 11" athletic body, and she would get goose bumps. She'd even seen Jack naked a couple of times. Once, when he was getting out of the shower, and another time when she walked in on him getting dressed. She wondered now, watching the familiar story, how big her brother's cock got when it was hard. Fingering herself furiously, she became lost in the thought of his cock sliding in and out of her. * * * * Stupidity should be painful, Jack thought as he drove home early. Some drunk driver hit the transformer near his shop with their SUV. The police and the power company told him it would be tomorrow before a new one could be installed. After talking to his very upset District Manager, Jack closed the shop, sending his two techs home for the night. And I still have to pay them their full salary for the day. That's going to screw my margin for the week, he thought as he finally pulled into the driveway of his parent's house. Jack was living at home until he could get enough money saved up to buy a house for himself and his girlfriend Mary. Once he had the down payment, he was going to get married, and move them both into their new house. But for now, he lived in the same bedroom that he grew up in. He saw Andrea's little Honda, and knew she was home. He didn't see Donna's car. Must still be at school, he thought. He entered the house through the carport. The house was quiet. He thought that maybe Andrea was meditating, which she liked to do. He took off his shoes, and walked quietly to the stairs, so as not to make too much noise. But he heard moaning sounds from the living room. It sounded like a dirty movie. Jack crept down the hall, and peered around the corner into the living room. Not only was there a dirty movie on, but also his sister was naked and masturbating. Jack almost left her alone, but he couldn't. He hadn't seen Andrea without clothes for a few years, and Andrea's body almost stopped her brother's heart. Andrea's about 5'6" tall, with red hair (this week), and a yoga sculpted body. She had perky B-cup breasts, and her nipples stood out like pencil erasers from her areolas. She was deeply in the throws of pleasuring herself. Jack couldn't help but get hard. He knew it was wrong, but his hand went instinctively to the tent that sprung up in his pants. He started stroking his cock, looking at the sex on the big screen, and then his sister on the floor. He gasped when she said out loud, "Oh, yes, Jack, that feels so good!" She was fantasizing about him! Jack didn't know what to think. He stood there frozen as his kid sister climaxed, letting out a grunt as she obviously gave herself an orgasm. Jack decided there was only one thing to do. He quickly shed his clothes, and revealed himself to Andrea. "Here's the real thing, if you want it," he said. Andrea screamed and tried to cover up. She then looked at her naked, aroused brother and was mesmerized by his eight-inch pole. She called his bluff, "Come here, and show me how much you love me, big brother." Jack strode over to her, and offered her his hand to help her up. Instead, she got on her knees, and brought her face equal to his cock. She then gave him a conspiratorial glance, as she leaned forward, and sheathed his manhood with her mouth. It was bigger than she had ever fantasized about, and she wasted no time getting to know every inch, bump, and vein of her sibling's cock. What she didn't have in her mouth, she stroked him with one hand. With her other hand, she fingered her clit, her moans adding to Jack's pleasure. Jack couldn't believe the blowjob he was getting, never mind the fact that it was from his baby sister. She really knew what to do, and before long, he was shooting his hot spunk down her throat. She took almost all of it; a little dribbled down her chin. Andrea stood up, pulled her brother's head down to her and kissed him in a not so chastely manner. A little bit of Jack's semen was still in her mouth, and she passed it to her brother with her tongue. "So that's what I taste like? Not bad," Jack told Andrea. "But now it's my turn, sis. Get on the sofa. Andrea sat down on the couch, and parted her legs, revealing her slit to him. Now it was Jack's turn to get on his knees. He took her left leg, and began to massage her foot with his hands. He sucked on her toes with his mouth and slowly worked his way up Andrea's leg. He stopped halfway up her thigh. He then focused his attention on the center of her womanhood. At first his fingered her clit. Then he inserted a finger into her cunt, working it back and forth, and in and out of her. He then replaced the finger on her clit with his mouth, rolling her nub with his tongue. Andrea was in orbit. She started grinding her pelvis into her brother's face. After several minutes of making her squirm, he stuck a finger into her hole, while with his other hand, stuck a finger into her ass. Andrea orgasm was explosive, and Jack's face was covered with her pussy juice. Hard again, Jack pushed his sister onto her back, and positioned himself between her legs. It was the point of no return, and Jack looked into his sister's eyes, and they both knew instinctively what to do next. As Jack lowered his cock to the folds of her pussy, Andrea was eager to accept his member. As Jack entered the taboo zone of his sister's cunt, he leaned down and kissed her. She returned his affections, stopping only to gasp as her brother entered her. She's so tight, Jack thought. He's so big, Andrea thought. Jack began to thrust in and out of her. She took one leg, and then the other, and wrapped them over Jack's shoulders. It allowed for deeper penetration, which they both enjoyed almost immediately. After what seemed like an eternity, Andrea stopped her brother and got on all fours. Jack caught on quickly; and they resumed their passions doggy style. The intensity of their sex peaked as they both orgasmed. Jack pinned his sister to the couch while his cock erupted inside her. "That was intense," Andrea said between gasps. "I've never cum like that before." "Me either," was all Jack could manage. He slowly pulled out of Andrea's cunt, and lay down next to her. "How long were you standing there?" Andrea asked, after catching her breath. "Long enough to see what you were doing, and hear you call out my name," Jack told her, as his hand lightly traced the curves of his sister's body. "How long have you wanted to fuck me?" "Probably since I was sixteen, and walked in on you in the bathroom. I see you're still keeping in shape," Andrea replied. Playing with Jack's flaccid member, she asked her brother, "Have you had sex with Mary? If not, she's missing out on a great cock." Jack blushed. The thought of his being embarrassed after what they just did amused him. "Oh, yeah, Mary definitely likes my cock. I thought that she gave great head, until you went down on me." The memory of the last time he fucked Mary brought the life back into Jack's cock; it slowly started to get hard at Andrea's touch. "Ready to go again?" he asked her. "You bet," Andrea replied. "Let's go to my room, so there's less chance of us getting caught. Donna would flip out if she caught us." "Yeah, she would. It's too bad, she's as hot as you are," Jack told Andrea, as they gathered up their clothes, and headed to her bedroom. Walking down the hall together, Andrea asked her brother, "Really? What about Donna turns you on?" "Everything. Her eyes, her hair, her body." "I'll bet you like her big tits," Andrea teased her brother. "Yeah, I do. I like your tits, and I like Mary's tits," Jack told his sister as they arrived at Andrea's room. It was a typical teenager room: posters of bands, hot guys, and a couple of female rockers. Andrea had a full sized bed, and she sprinted to and jumped onto, landing on her back. "Come here big brother, I have a present for you." Jack walked to the edge of her bed, "Oh? I've got something for you," he playfully replied. As he lay down beside his sister, he reached over, and put his hand on her face. As animalistic as it was moments ago, he wanted to take it slowly, and get to know his sister's body (and drive her crazy, too). He caressed Andrea's cheek, moving his hand up and around her eyes. Then, with one finger, he lightly touched her nose, moving towards her mouth. As his finger outlined her full lips, she tried to capture his finger with her tongue. But Jack proved to be too elusive, as he moved his hand over her chin, and slid it down her neck towards her chest. While Jack was doing this, Andrea's hand hunted for her brother's cock. She found his right leg, and she the zeroed in on his manhood. By this time, Jack was tracing one of her breasts with his hand, spiraling up to her nipple. All the while, they gazed at each other with a combination of love, and lust, ramping up the tension. When Jack reached his sisters nipple, he noticed Andrea had goosebumps. Figuring that she liked this, he began to pinch her nipple, rolling it between his finger and thumb. At the same time, Andrea's hand explored her brother's manhood with her hand. She ran her fingers up and down the shaft of his cock, then ran her fingers through the tufts of hair on his ball sack. Instead of playing with his sister's other breast, Jack moved his hand down her body to her pubic region. He then swung one leg over Andrea, and he was now astride her. "Jack, my other breast feels left out," Andrea mockingly pouted. Jack smiled, leaned over, and began to explore the "left out" breast with his tongue, all the while playing with her slit. Andrea said, "Jack, I know you want to take this one slowly, but if you don't put your cock in me now, I'm going to pluck all the hair off your balls... one by one!" "Okay, but lets do something different this time. Lay on your side," Jack instructed. As she turned on her side, Jack maneuvered himself so that he was between her legs, and had one of Andrea's over his hip. He then moved forward, and plunged his cock into his sister's moist entrance. Andrea loved the feeling of Jack's cock sliding into her again, and groaned at how wonderful it felt to have his stiff pole in her twat at this angle. Jack began to rock back and forth, his cock glistening with his sister's natural lubricant. Jack loved the feeling of Andrea's pussy enveloping his cock, and his rhythm increased. Andrea, too enjoyed the sensation of her brother's taboo violation of her, and she knew it wouldn't be long before she came again. Jack couldn't hold back any longer, with one final push, he cried out as his cock spurted over and over into his sister. Hearing Jack grunt pushed Andrea over the edge, and she too tensed up and her orgasmic dam burst. A short time later, Andrea awoke to find her clothes folded neatly on the bed, and heard the distant sound of what could only be Jack showering. She smiled to herself, and then noticed a note on the clothes. She picked it up and read, "You shouldn't leave your clothes lying around," with a smiley face as the signature. Andrea laughed, and lay back down under the covers falling asleep with a satisfied smile on her face. Andrea & Jack Ch. 02 It would be helpful to read the first chapter of this story, so that this story will make more sense. As always, this is all made up. A few weeks went by since that fateful night when Jack and Andrea crossed over the taboo line with each other. They managed to sneak some time together, and they helped themselves to each other, learning more and more about each other sexually. Today was Jack's day off, and as part of the "rent" that he paid his parents, he was cutting the grass. Jack was wearing denim shorts steel toed boots, and safety goggles. He was shirtless, but he was wearing a baseball hat. As it was, it was hot and muggy outside, and his athletic chest glistened with sweat. His other sister Donna was visiting her boyfriend Brad across town, and their parents were on a cruise, celebrating their anniversary. Finishing the back yard, Jack moved to the front. As he was finishing the lawn, Andrea pulled up in her Honda. Jack could see that she had her boyfriend, Steve with her. Jack liked Steve; they had been in some classes together in high school, and while they weren't close friends, Jack new Steve was an okay guy. As Andrea got out of the car and waved at her brother. Steve came around from the other side of the car, and put his arm around his girlfriend. Just under six feet tall, Steve didn't really have an athlete's body, more lean and wiry. He had sandy blonde hair that came down to his shoulders, which was kept in its usual ponytail. He was in shorts, and had a t-shirt on of some obscure band. Jack stopped the mower, and greeted his sister and her boyfriend. "What have you guys been up to?" Steve said, "Not much. I have a new CD that I want Andrea to hear." Steve stared at Jack in a way that was slightly unnerving. "Maybe when you're done, you could give it a listen." "Sure, why not," Jack replied. "I'm always on the lookout for something new." Andrea kissed her brother on the cheek and said, "See you inside then." Ten minutes later, Jack finished the lawn. He put the mower back in the garage, and went inside. On the table, he found a glass of lemonade, and a note that read, "Thought you'd like this. Come see us when you're out of the shower. Andrea." Jack downed the drink in no time, and headed to his bedroom. He passed his sister's room on the way. Andrea and Steve were sitting on the bed, listening to the music, not even noticing he was there. Jack got to his room, stripped, and headed for the bathroom after wrapping a towel around his waist. While soaping up, Jack wondered if Andrea and Steve had had sex yet. They'd been going out for two weeks, and Andrea seemed really happy. He pictured Andrea giving Steve head. The thought of his sister with Steve aroused him, and his cock hardened. He soaped up his cock and began to stroke it. He picked up momentum as the scene shifted to Steve taking Andrea from behind. He wondered what Steve's ass looked like. He then wondered why he was wondering that. Jack stopped masturbating and finished his shower. He dried himself off, and went to his sister's room to tell Andrea and Steve that he would come back after he got dressed. As he got to Andrea's door, he noticed that it was almost closed. He looked in, and it was as if they new what he was thinking. Andrea was sitting on the bed, giving Steve a blowjob. Jack took in the scene. Steve was naked from the waist down, his hair freely flying about his head, having been released from the ponytail. Andrea looked at the door, and motioned her brother to join them. Jack entered the room and crossed the room to his sister's bed. Andrea stopped her oral pleasuring of Steve, and she said, "Want some company?" Steve looked a bit shocked when he saw Jack, but answered, "I don't mind sharing, if you don't?" Instead of looking at Jack, he said this to Andrea. "Not at all," Andrea said, and picked up where she left off. Jack got on the bed. He then positioned himself so he could play with his sister's pussy. He could see that Steve did a good job of getting her going; she was very wet. Jack bypassed fingering her, and started to lick her slit, and wrap his tongue around her hardened clit. He knew that his sister liked it, and she moaned her approval, which vibrated around Steve's cock. Steve gasped as he enjoyed both the feeling and sensation of Andrea's mouth on his manhood. But he also liked the looks of Jack's eight-inch turgid cock. He stripped off his shirt, reached down, and lightly ran his fingers up and around his girlfriend's brother's pole. Jack felt the hand on his cock, but kept on eating his sister's pussy. It was when the hand wrapped itself around his member, that he realized it was Steve's. It felt good. Andrea saw Steve's hand on her brother's cock, and it turned her on more. She slid her mouth off Steve's dick, and sat on her brother's face. Steve took the hint, and his mouth zeroed in on it's objective. Jack knew the tongue on his balls were Steve's. If it hadn't felt so good, he would have stopped him. But Steve seemed to know what he was doing. Soon, Andrea turned around, so that she could get a better look. Steve licked up and down Jack's cock, enjoying the feeling of it on his tongue. He'd only ever been with one guy, but he knew he liked guys as well as girls. He shifted so that he could rub Jack's balls with his hand. He liked the feeling of having another man's balls in his hands. Jack seemed to like it, too. Andrea joined her man, and they both took turns licking and sucking Jack's cock. All the attention caused Jack to tense up and shot rope after rope of semen from the purple head of his cock. Both Steve and Andrea were hit in the face with some of Jack's seed, while the rest landed on Jack's chest and belly. Steve and Andrea lapped up the excess, and then licked each other's face, so as not to waste a drop of Jack's warm product. Andrea couldn't believe how turned on she was. She grabbed her boyfriend, and threw him on his back next to Jack. She then quickly impaled herself to the hilt on Steve's seven-inch cock. It was a little thicker than Jack's and she bounced herself up and down on his pole. Jack looked at the ecstatic look on Steve's face. He leaned over, and kissed his sister's boyfriend. Steve eagerly accepted Jack's tongue, and they kissed while Andrea's sliding up and down Steve's cock. Jack rubbed his hands up and down Steve's hairless body. Steve could take no more, and lifting his ass off the bed, he fired his load into the now-orgasming Andrea's cunt. It seemed to go on for an eternity, but soon Andrea slipped off her boyfriend, and lay down beside him on the opposite side from her brother. Jack saw Steve's flagging cock, and moved down to it. He caressed Steve's hairless sack, and pointed Steve's cock to the ceiling. He then leaned over, and put the shrinking member in his mouth. He tasted the mixture of Steve and Andrea's sex juices, and he could distinguish his sister's flavoring on the pole from that of her boyfriend's. Sweet and salty flavors met his mouth, and Steve's juices differed only slightly from his own. Licking the shaft quickly brought Steve's cock back to stiffness. Jack began to bob up and down on Steve's prick, and he was really getting into it. Steve enjoyed having Jack blow him. He felt the familiar stirrings of another orgasm building, and said, "Be ready, Jack, I'm cummminngg!" He shot his load into Jack's mouth. Jack for his part, sucked down every last drop, but saved a bit to kiss his sister with. When they broke off their kiss, Andrea told them both, "That was the hottest thing I've ever seen! I didn't know either of you like guys, too. It's like winning the lottery!" "I didn't realize myself until just now, but I enjoyed it," said Jack. Looking at Steve, he said, "You, sir, could teach a class on how to suck cock. That was fantastic." "Thanks," replied Steve. "I've only been with one other guy. I mostly like girls, but I practice cock sucking on some cucumbers and carrots that my mother usually has in the fridge." "Jack, Steve's fucked me, now it's your turn," Andrea said to her brother. "Twist my arm, sis," was his reply. Andrea got on all fours, and Jack, now hard again, thrust himself into his sister's pussy. Steve watched as brother and sister became as one, fucking in front of him. Steve began to stroke himself, turned on not only by the fact that he was this close to sex, but that they all had broken several taboos of sex. Jack and Andrea were oblivious to this. They both concentrated on the sensation of feeling the other one on their sex, Jack picked up the pace a bit, and Andrea responded with moans of pleasure. Then Jack took Andrea by surprise by pulling her up and back onto him. The result was a reverse cowgirl that she had seen in some porn she found on the internet. While she enjoyed it, she wanted to see the look on Jack's face when the both came. She rotated on her brother's cock so that she could look into his eye's. Steve saw this as an opportunity to get into the action. He got behind Andrea, and spit on his hand. He then used the wet fingers to rub around Andrea's ass hole. Andrea stopped, wondering what Steve was up to, but Jack caught on quickly, as he gave Steve a nod of approval. Steve put spit on his cock, and pointed its purple head at Andrea. As it got to her sphincter, Andrea knew then what Steve planned. "I'm not so sure about this, Steve," she said. "Just relax baby, I'll take it slowly." Steve slowly inserted his hard cock into Andrea's ass. Andrea wasn't too keen on the idea, until she felt Steve's cock bump against her brother's cock that was in her cunt. Then she helped him inside her and told them both, "I'll set the pace." Slowly she eased herself up and down the two cocks. The initial pain was replaced by the bliss of being fucked by two cocks. She alternated pushing hard against Steve's cock; then the next down stroke, Jack would feel her weight on his. This went on for about a dozen strokes. Andrea could take no more, and she dropped all her weight on Jack's cock, as she tensed both holes around the two cocks, and shrieked in orgasmic bliss. Steve was at the brink, but when Andrea clenched down on his cock, and felt her spasming cunt clamp down on his cock, he let loose pulse after pulse of semen into Andrea's bowels. Feeling both, Jack cried out as he came in Andrea's pussy. Jack raised his arms to catch his collapsing sister, supporting her with his elbows on the mattress. He could then feel Steve's weight, as he leaned forward on her. Then Steve leaned backwards, and watched as his shriveling sex organ was pushed out of Andrea's anus. Andrea rolled off her brother, and hit the bed beside him, face first. When they all had the energy to speak, Steve said, "I've never cum so hard in my life. That was amazing!" "Yeah," was all Jack could manage between pants, "I think Andrea's passed out." "Let's let her sleep. I need a shower, and I need help soaping my back," Steve winked Jack. When they could manage it, they got off the bed and headed for the bathroom. It had a garden tub, and a large shower. Jack got Steve a towel, and placed it on the toilet, as Steve turned on the shower, and adjusted the temperature of the water to a good level. Jack looked at Steve. He hadn't noticed what a small, tight ass he had. He went over and put his arms around his sister's boyfriend. "Be gentle; it's my first time," he said, only half kidding. He ran his hands up and down Steve's body. Stopping at his cock, he then added, "You'll need help cleaning that beast," and gave a gentle squeeze to Steve's balls. "That's what I was hoping for. Let's get in before we use up all the hot water," Steve replied. The stepped in and closed the shower door, Jack pulled Steve's face to his, and kissed him deeply. Steve returned the kiss with gusto. As their tongues darted in and out of each other's mouth, the two explored each other's body. Steve said, "You've got a nice ass there, buddy." He reached for the soap, "We have to get it nice and clean." "Okay, but I think your cock needs and extra special cleaning, too," Jack said, taking the soap from Steve's hand. As Jack went to his knees, he grabbed the washcloth that was in the shower and lathered it up with the soap. He then put three fingers on Steve's cock, and held it up so that he could wash it. As Jack went this way and that with the cloth, Steve's dormant pole began to look Jack in the eye. He made sure that the penis was rinsed off by placing it in his mouth. The sensation of the water hitting his body, and Jack sucking his cock was pure bliss for Steve. But he had to forego his pleasure, as he had a different purpose for his dick. He told Jack to stand up, and with another cloth, began to soap down Jack. He started at his face, and worked the lather up all over his upper body, stopping at the waist. He then knelt down, and soaped up Jack's legs, working the soap all over, save his cock and ass. "Would you like a thorough cleaning, Jack?" Steve asked coyly. "You better believe it," was Jack's response. Jack then worked the washcloth gently on Jack's balls, working around the soap, and then cleaned Jack's cock. Steve pumped Jack's pole a couple of times, and then said, "Turn around, and lean forward." Jack did as instructed. Steve took the cloth, and worked it all over Jack's ass. He then told Jack to spread his legs just a bit. Doing so parted the cheeks of Jack's butt, and Steve wasted no time soaping it up. He then reached around and grabbed Jack's cock. As he stroked his girlfriend's brother with one hand, he worked a finger up and down the crack of Jack's ass. Jack was startled at first when he felt one of Steve's fingers poke his sphincter, but he relaxed, and realized it felt rather nice. Then, Steve added another digit, and Jack enjoyed that, too. "Jack, this might hurt a bit, but there's some lube on the shelf here,' Steve said. He'd stopped masturbating Jack, and pulled his fingers out of the dark place. He took the bottle, and liberally dosed Jack's crack with it, and rubbed some on his throbbing cock. "Ready?" "Yeah," Jack replied as Steve's cock penetrated his ass. It hurt a bit, especially since Steve's cock was so thick, but Steve also moved slowly into him, stopped, and pulled back, almost withdrawing his rod. But then Steve slowly pushed back in, a little deeper this time. He repeated the process until Steve fully buried his cock in Jack's ass. Jack was hard. He was turned on. He began to enjoy the feeling of the cock in is ass. "I never imagined this, but it sure feels good, Steve," he said. "Thanks. You're so tight, it really feels good on my cock. Let's not rush and enjoy it," Steve replied. Jack slowly moved back and forth on the cock that was impaling him. Each time Steve was fully inside him, his cock twitched. The slow thrusting became a little faster with each stroke, and soon, Steve was pumping Jack's ass like piston. Jack tried tightening his ass' grip on Steve's cock. Both moaned with the pleasure that it brought. Then, Jack felt Steve give a final push, tense, and felt his new friend's cock pulsing cum into his bowels. He could feel the warmth of Steve's spunk inside him. Combined with the final thrust, Jack's cock spasmed, and he, too, came, splashing his seed on the wall of the shower. "That was great," said Jack. Then an evil smile crossed his face when he realized he was still hard as a rock, "It's you're turn now," as he kissed Steve again. Steve, still a little weak kneed, turned around in the shower. Jack treated Steve's ass as gingerly as his had been. "Don't worry about sticking any fingers up there. I've done this before," Steve told Jack. Jack took the lube, and rubbed on Steve's crack. He then put a liberal amount on his cock, and put it to Steve's hole. Steve was right; Jack's cock buried itself inside Steve smoothly. "I may have only had sex with one guy, but we fucked like rabbits," Steve explained. Steve started back and forth on Jack's cock. It was a little bigger than his ex, Mark's cock. However, it felt good having Jack inside him. As before, they started slowly, and picked up the pace. When they were at a good pace, Jacked started pumping just a little harder. Steve gasped as Jack pushed the full length of his cock into his ass, and orgasmed. As Jack pulled out, a little trickle of his semen leaked out of Steve's ass. "That was so hot guys," Andrea said, standing at the doorway of the shower. "I think I came just watching you two." ****** The next day, Jack awoke in his bed, on his side. In front of him was his sister, behind him, Steve. Jack was sure his hard on was because it was morning wood, but he gently slid down slightly, carefully parted his sister's legs. He then slowly guided his cock into her cunt, stopping when it was all the way in. Andrea stirred a little bit, but didn't seem to wake up. Jack began to slowly work his shaft in and out of his sister. Slowly, her eyes opened, and realized what was going on. "That's a nice way to wake up," Andrea told her brother. He was about to respond when he felt Steve's cock pushing against his ass. "I see you're awake, too," Jack said to his sister's boyfriend. "Lets do this properly. Andrea, get on your knees." She did as she was told, temporarily breaking the contact with her brother's cock. Jack got behind her, and put his cock to the hilt in her pussy. Steve then got behind Jack, and slowly penetrated his ass. Three became one, and Jack set the pace. He would move nearly off Steve's cock as he penetrated his sister. On the backstroke, he would impale himself on Steve. Back and forth, three moving as one as their goal was to give each other pleasure. Jack felt he was getting the best of both worlds, and he was both the fucker and the fucked. The thought of that turned him on more, and his movements became more rapid. Steve held onto Jack's hips, just as Jack was doing the same to Andrea. All three of them moaned, as each was being pleasure differently, but with the same goal. Suddenly, Steve pulled Jack back onto his cock as his was the first orgasm. The sudden movement, coupled with the warmth of Steve's spunk pulsing into his ass, sent Jack over the brink. He pulled his sister back forcefully on his cock, and cried out as he shot his load into the forbidden zone of his sister's cunt. Andrea, realizing that both her men came, explosively orgasmed herself; her juices mixed, with that of her brother's and Steve's sperm, showered all over Jack's cock. They fell into a heap on the bed in each other's arms, reveling in the afterglow. Finally, Jack asked, "What do you guys want for breakfast?" Andrea & Jack Ch. 03 If you haven't read the other parts to this story, I suggest you do. Please leave feedback. I want to hear from you. Thanks for all the suggestions I've gotten so far. -Jack * "What's wrong, Andrea," her brother Jack asked. "It's Steve," Andrea said between sobs, "We broke up." Andrea grabbed another tissue and blew her nose. They were in the living room of the house they lived in with their parents, and sister Donna. "What happened? You two seemed so happy," Jack said, putting his arm around her sister as they sat on the sofa where they made love. "I thought we were. I went over to Steve's to surprise him, and I found him on the back deck of his house, giving the captain of the school baseball team a blow-job." "You know he likes guys," Jack said remembering how he and Steve shared Andrea, and themselves with each other. "Yeah, but I knew about you; I had no clue about Mike. I told Steve to enjoy him, because that's all the sex he'll get from now on," Andrea said as she buried her face in her brother's chest. Jack put his arm around her, and lightly rubbed his hand up and down Andrea's back. It was early in the morning, so Andrea was still in pajamas, while Jack was in a t-shirt and running shorts. "I'm sorry I wasn't there for you last night, sis. I was over at Mary's house kinda late. We were in the hot tub, and well, you know." Jack didn't want to elaborate. He didn't want to rub in Andrea's face that he and Mary fucked in almost every room in the house. "It's okay, Jack," Andrea told her brother. "You couldn't have done anything for me anyway." Jack smiled at his sister. "Yes, I could have done something," he told her as his hand slipped under Andrea's shirt, seeking out her tits. "I could have done this." His hand found its target. Andrea's nipple was already hard in anticipation. Jack slowly caressed one of his sister's breasts, lightly brushing over the nipple. "Jack, please," Andrea gasped, "don't," gasp, "stop," she told him as her mouth sought his. Their lips met and their tongues searched for and danced with each other. Andrea put a hand on her brother's leg, and moved up to find his cock and balls. Jack broke off their kiss long enough to remove his and Andrea's shirts. Jack had almost no hair on his muscled chest; while Andrea had great B-cup breasts that Jack couldn't keep his hands off. They resumed their embrace, and Andrea found the object of her lust, Jack's cock. It was already hard, with a slight trace of pre-cum on the head. Andrea passed her hand slowly down the rigid shaft, and started to lightly rub her brothers scrotum. "I love it when you do that, Sis," Jack told her. He sat up enough to take of the shorts; he wasn't wearing underwear. Andrea stopped to let him take off his shorts, but then returned to play with her brother's manhood. Jack kissed, licked, and nibbled his way down his sister's face and neck. As he sought out the breast that wasn't getting attention, Andrea took off her pajama bottoms. She was still wearing the pink thong that Jack had given her on the sly. He thought it showed off her ass better, and who was she to argue? Andrea would have let her brother orally pleasure her tits, but she wanted his cock more. She leaned over, and kissed the tip of Jack's cock. She then ran her tongue in a downward spiral around his cock to the base, where she sought out each testicle, and gave it a cute little kiss. She then returned to her main objective, replacing her mouth with her hand on her brother's ball sack. "God, you know I love it when you do that," Jack told his sister. That was about all he could muster as Andrea worked her mouth this way and that way around his cock. Finally, she took all of him in her mouth. She hadn't been able to do that when they first made love. But thanks to having both Jack and Steve's cocks to practice with, she could take her brother's entire rod in her mouth without much trouble. All Jack could do was lay back and enjoy watching his baby sister give his cock a tongue bath. He could feel his orgasm building as Andrea's head bobbed up and down his manhood. "Andrea, be ready... I'm going to..." He couldn't finish the sentence. Jack's orgasm consumed his attention as his cock erupted in Andrea's mouth. Pulse after blissful pulse of his cock sent what always felt like a gallon of semen into his sister's mouth. Andrea did her best to swallow all of it, but a little bit trickled down her chin. Ignoring his seed, Jack brought Andrea's face to meet his in another round of kissing. He tasted himself in and around her mouth, but it didn't bother him. "I thought I was supposed to make you feel better, Sis, not the other way around," Jack playfully scolded Andrea. "That did help me feel better," Andrea said, with a mischievous look on her face. "But you can still help me feel better," she told Jack as she started to lie back on the sofa. Jack didn't need to be told twice. He got on top of her and picked up where he left off. He worked his mouth over each breast equally. While he did that, his right hand moved down her body to her sex. He slipped his hand under the waistband of Andrea's thong, and his hand slipped through what little pubic hair his sister hadn't removed, to her dampening pussy. Andrea, already breathing hard from the excitement of this taboo act with her brother, gasped as one of Jack's fingers found her clit. Jack slowly worked his finger over her nub, and he stuck another finger into her slick cunt. Andrea gasped again. After a few moments of manually pleasuring Andrea's pussy, he wanted a taste of his sister's love nectar. He shifted so that his face was even with his sister's cunt. He pulled off the thong that he gave her as a memento of their first foray into the forbidden zone. He then kissed around his sister's creamy thighs, zeroing in on her cunt. * * * * Donna hated working double shifts at the hospital, because it meant more money. It would be better money when she became an RN, but it also meant that she was dog tired, and wanted nothing more than a hot bath and her pillow. Pulling into the driveway of her parent's house she saw that Jack and Andrea were still home. I guess they're lucky, and sleeping in, she thought. Well she was going to be joining them in the land of nod soon. Donna quietly entered the house. She was going to go straight upstairs, when she heard some moaning and grunting from the living room. Oh, great, Pinky's watching porn again. Andrea told her sister how she liked to masturbate while watching porn on the living room's big screen TV. Donna tried to walk even more quietly, so that she could give her sister some privacy without embarrassing her. She looked into the room, and noticed the TV wasn't on. And then she saw it. Andrea had sat up on the sofa, very topless, and very into her sexual pleasure. She couldn't see if her sister was fully naked, as the sofa faced away from the doorway. Donna moved closer, and watched as her sister bobbed up and down. She's having sex, Donna realized. She also felt a little strange, because the sight of her sister getting laid excited her. Then, she got a real shock. Andrea turned around, and disappeared on the sofa. Then Jack (!) appeared from sofa, and moved a bit forward, and was obviously thrusting his hips. Oh... My... God! Her brother and baby sister were fucking each other. Donna couldn't believe it. In fact, she didn't believe it. She thought is was an elaborate joke they were playing on her. Donna didn't want to walk over to the couch to see that Jack was humping a pillow, while Andrea sat on the floor, trying not to giggle. Andrea had a plan. She quietly backed away from the doorway, and went down the hall to the kitchen. She was going to sneak up on them by going through the kitchen, and into the dining room. The dining room opened out on the far end of the living room from where Donna had first observed the prank. It has to be a prank, she thought. They were always pulling pranks on their big sister. She was going to spoil this one for sure. Andrea stealthily made her way to the dining room, after taking her shoes off in the kitchen. The dining room had hardwood floors that always made Donna's hospital shoes squeak as she walked on it. When she got to where she could see the sofa, she realized there wasn't a prank. Jack was still behind his sister, making those same thrusting motions. Donna however, realized her siblings were naked, and that her brother just wasn't thrusting; he was indeed fucking Andrea. And they were both enjoying themselves. "I want back on top, Jack," Andrea told her brother. Jack pulled out, and Donna could see her brother's eight-inch cock, glistening with their sister's juices, gave Donna even more conflicted feelings. Absently, and without even thinking about it, Donna slipped a hand into her scrubs, and started to rub her pussy. The sight of her sister impaling herself on Jack's pole started her heart racing, and she worked her other hand under her shirt and bra, and fanned her fingers over the nipple of one of her ample breasts. Soon, unbeknownst to each other, Donna's masturbation rhythm matched her sister's motion on her brother. Their intensity quickened, and soon Jack's hips drove straight up into Andrea, and his orgasm was accompanied by a primal growl. Andrea matched her brother's growl with a shriek of her own orgasm. Then Jack and Andrea heard another grunt, coming from the dining room. Donna, leaning against the doorway, slowly sank to the floor. The hand that had been on her twat was easing her down, while her other hand was still under her scrub shirt. They both guessed the obvious: Donna had orgasmed while watching them fuck. Andrea jumped off her brother, and crossed the room to her big sister. "You okay, Pinky?" She asked. They both called each other Pinky. "I'm alright. What the hell is going on here?" Andrea asked. "I think it's pretty obvious, Donna," Jack answered crossing the room and getting on the other side of his big sister. "Let Andrea and I help you over to the sofa." Andrea winked Jack at; he smiled back. Slowly, they helped their sister over to the sofa. Seated, Jack and Andrea stayed on either side of her. "How long has this been going on?" Donna asked. "A couple of months, give or take," Andrea replied. "You aren't going to tell anyone, are you?" As she asked her sister the question, Andrea's hand slipped under her Donna's shirt. "You both know it's not right," Donna said. Jack slipped his hand under the shirt as well. "Mom and Dad would... Oh!" She stopped when both Jack and Andrea had each one of her breasts in her hand. "You guys, shouldn't..." her voice faltering as they tweaked and pinched a nipple. "Pinky, you look warm in this," Andrea said. "Let's get those clothes off you. Andrea pulled up the shirt over Donna's head. Donna offered no resistance, because her sensitive tits were being pleasured. Jack moved to take his big sister's pants off. Andrea replaced her brother's hand with her own. After Jack got the pants off, Andrea straddled her sister's lap. She leaned forward, and kissed her sister. Donna returned the kiss. Her tongue delightedly "fought" with the invading tongue of her sister. Jack slipped a hand behind Donna's back, and unhooked her bra. Andrea noticed the freedom of movement her hands now enjoyed, and she lifted up the cups to reveal her sister's tits. Unlike Jack, Andrea had seen her sister naked more times than she could count. She always wondered how big tits felt. Donna, for her part, was lost in the pleasure her sister was giving her. She broke off the kiss, and tossed the bra aside. Andrea moved to put her mouth on those delicious orbs that had been totally freed from their fabric prison. When Andrea flicked her tongue on one of Donna's nipples, Donna felt an almost electric charge from the tip of the nipple, straight to her cunt. Donna reached out, and sought her sister's tits. Andrea would have none of it. She took Donna's hand, and put it between her legs. Donna quickly got the message, and searched for her sister's clit. Finding it and fondling it, Donna sent a similar charge up her sister's spine. Jack was enjoying the show. He watched with undivided attention as his sisters' explored each other's body. He could feel his erection returning, but wanted to wait for the right moment. Donna pushed Andrea down on the sofa, and began using her tongue to map out her sister's body. Andrea stopped her. "Why don't we go to your room and continue this, Pinky? Come on Jack, you too." "Like you really thought you could keep me away?" was his reply. They all got up, and went to Donna's room. Donna had the second largest bedroom in the house. Because she could, Donna had bought herself a King sized bed. Although she used her desk to do written assignments, she did all her reading on her bed. Donna ushered them in, and closed the door. Jack and Andrea both jumped on the bed. Jack move to prop himself at the head of the bed, Andrea met her sister at the foot. On her way there, Donna removed her boy short panties, and Jack and Andrea got their first view of their big sister's shaved pussy. "Now where was I? Oh, that's right. On your back, Pinky," Donna ordered her sister. Andrea complied. Donna got on the bed, and with cat-like motions, she got close to her sister, and picked up where she had left off. She worked her mouth between Andrea's breasts, and traced a lined on her abdomen with her tongue. She paused only to tease Andrea's navel, which Donna knew was ticklish. While Andrea giggled and flinched, Donna raised her head, and plunged her tongue along Andrea's slit. Andrea felt like the wind had been knocked out of her, turned on by her sister's trick. She would forgive her, because Donna was orally working her cunt magnificently. Donna shifted herself around, and presented her sex to Andrea. Andrea had never seen a girl with a shave cunt before, and this was something new to Donna since they went swimming last month. Tentatively, she passed her hand over the shaven area, and it was smooth to the touch. She then found her sister's clit, and began to pleasure it. Donna was really enjoying her first taste of pussy. About a year ago, she and a friend had decided while drunk one night to try out each other. Donna's friend had no problem eating pussy, but Donna was hesitant to return the favor. But now, the smell of Andrea and Jack's juices drew her to her sister's cunt. She sighed when Andrea placed a hand on her twat, and nearly lost her breath when Andrea finally began to use her mouth on her. Jack was enjoying the show. He was hard as a rock, but he was under the spell of seeing his sisters in a 69. Jack leaned forward, and added his tongue to Andrea's on Donna. That was too much stimulation for Donna. Her hips drew up, and she spasmed as her second orgasm of the morning overtook her. Andrea knew she was soon to follow, and she tensed as she orgasmed, grinding herself into Donna's face. Jack, however, didn't stop. He kept working his tongue over Donna's clit, and then stuck his tongue in Donna's hole and flicked it in and out. Donna cried out, and nearly fainted when she was overcome by yet another orgasm. Jack smiled at his handiwork, but also made sure Donna was all right. She didn't say anything, but turned slowly, and eyeing Jack hard cock, zeroed in on her objective. If Jack didn't know better, he would have thought that she meant to hurt him. But no, something primal had overcome Donna. Lustily, she began to work over her brother's rod, Tracing and licking it with her tongue. She then took all of him in her mouth, and unlike her sister, Donna again used her mouth organ to stimulate the underside of his cock. Jack wasn't sure how much longer he could hold out. "Donna, get on my cock, NOW!" Jack demanded, with a hint of plea in his voice. Donna grinned, slid her mouth off her brother's tool, and said, "I thought you'd never ask." Donna straddled her brother, and lowered herself to his throbbing manhood. I've gone this far, I might as well go all the way, She thought as her brother's cock entered her; the last taboo was broken. Donna didn't care. Jack's cock felt wonderful inside her, like it belonged there. She had planned to start slowly, but she was so worked up, she very quickly switched to a quick up and down motion on Jack's cock. Both moaned, letting the other know that it felt blissful. Andrea watched as her brother's cock penetrated his sister's pussy. She saw both of their eyes glaze over in enjoyment of each other. Andrea moved over to Jack, and lowered her cunt onto his face, where he immediately began to work over her clit. Andrea looked into the mirror behind Pinky's bed, and saw the joy on her sister's face. Then, Donna's motions up and down became more rapid, and Donna suddenly dropped down on Jack's cock. Throwing her head back, Donna yelled, "Oh fuck yeah!" as her orgasm overcame her. As Jack tensed up, Andrea exploded her love juice on Jack's face just before he emptied his load into his other sister. Jack could feel his cock pulsing, as he came, and felt Donna's vaginal walls tense around his cock as he did. The girls somehow managed to lift themselves off of Jack. They then lay down on either side of them on the bed. He kissed each sister, Donna first, then Andrea. For their part, they kissed their brother, and nuzzled his chest. They fell asleep, still glowing from their forbidden tryst.
