Names have not been changed since my girlfriend already knows. ***** I had met my girlfriend online via Facebook. We lived states apart and I figured that it would never work. I was wrong. Months later saw me moving to her state, where I met her in person for the first time. We hit it off and moved into a two bedroom in a dingy side of town. We had great sex back then, but declined a couple of months later as I started realizing I didn't like her personality as much as I thought I did. She prides herself in being a very intelligent woman, which she is, but she also has this habit of being however she wants. If she wants to act like a bitch, then she will and no one can tell her differently; but let someone do the same thing and she gets a stick up her ass about it. Now enter her sister. I met Stephanie while my girlfriend and I were visiting her grandparents. Stephanie came over wearing a short skirt and a tight shirt that hugged her ample breasts in a very complimentary way. I could not help but stare whenever I was sure no one was looking. Her sister did though. Days later, her sister needed help moving some furniture. My girlfriend being trusting of me agreed to lend me to help. I got a uhaul and drove Stephanie over to her apartment and helped her pack the uhaul after she changed into a pair of flats. Now, let me describe her. She is 5 foot 4 while her sister is 5 foot 2. She is thick in all the right places and has beautiful olive skin. She has a flat stomach, whereas her sister is chubby. She has blonde hair while her sister has black. Anyway, we get on our way to the storage unit and she started squirming in her seat. I looked over at her and saw her attempting to scratch her back. "Need help?" I asked. "Yes please. I can't seem to get it." Was her reply. I patted the seat next to me and said, "You'll have to come closer, I can't reach that far and drive." I grinned. She looked at me and shrugged before unbuckling her seatbelt so she could scoot closer to me. As soon as she got close enough to me I slipped my hand under the back of her shirt and back scratching her back. "A little to the left. Up. Up." She groaned out as she tried to match my nails with her itch. I attempted to scratch where she wanted me to but her bra was in the way. "Your bra is in my way, Steph." I said. At that point I wasn't thinking about sex or even taking advantage of her. She immediately responded with, "Unclip it!" I quickly unclipped her bra with one hand and began scratching. She began squirming with renewed vigor, moving to keep my nails where she was itching. She moaned out, "That feels so good." I don't think she realized how much she was losing herself in the moment because he left hand had dropped to my lap and was rubbing my right inner thigh. Her eyes were closed as she indicated that her right shoulder itched. I moved her bra strap down her right arm and began scratching her shoulder. She seemed to get annoyed with her bra because she removed her hand from my leg and quickly removed it and threw it on the seat next to her. This shocked me. I had gotten a glimpse of side boob when she lifted her shirt to remove her bra. I couldn't help but get a little hard. She kept moving under my nails as I attempted to check out her braless breasts and watch the road while scratching her bare flesh at the same time. Eventually her hand found its way back to my inner thigh and she went back to rubbing it as she moaned. "Rub it please?" "Of course." I responded quietly. At this point I would have tap danced bare foot on hot coals if it meant touching her some more. I began gently massaging her back as I pulled into the storage place. Things paused for a moment as I typed in the storage code. The gate rattled open and I drove the truck in. I drove to her drive up storage unit at the back of the facility. Stephanie looked at me, "Would you mind giving me a quick massage? I know it's a lot to ask but I really need it." I nodded and she laid down with her head face down on my lap. This made my dick twitch and I'm sure she noticed since I was wearing basketball shorts. I took a deep breath and pulled up her shirt, at which point she let out an exasperated breath and removed it entirely, giving me a spectacular view of her sexy 21 year old breasts. My dick at full mast I waited for her to lay down once more. Once she did I noticed she had inched a little further into my lap, her cheek now resting on my bulge. I took another deep breath and began massaging her back. She began moaning as I gave her a slow and deep massage. As I did, she slowly moved her head, her hands now up above her head and on my lap. I made no move to show that I noticed. I wanted to see where she would take this. As I moved lower down her back she moaned a little more and did the unexpected. She moved a little closer to me so that her face was entirely in my lap, my dick press sidelong against her mouth, but still I made no move to show I noticed. As I began to massage above her skirtline I felt her open her mouth. My cock was already straining in my shorts but with her mouth open it moved to fill the empty space, desperate to get free. My cock now resting sidelong in her open mouth she began massaging it with her lips. I let out a noise of pleasure as I slipped my hands lower, my cock twitching with each move she made with her mouth. Now I know what you're thinking, "how could I do this to my girlfriend?" Well, I didn't think of my girlfriend at that moment. Instead I now had my hands under the waistband of her sister's skirt and was rubbing the top of her ass. At this point she was attempting to get my dick into her mouth tip first but she was having trouble with my shorts in the way. I was about to help her when she simply pushed my right short leg up and exposed my dick momentarily before taking it into her mouth. She deepthroated me instantly, taking 8 inches of my now solid dick down her throat. All reservations on my part flew out the window as I pulled my hand out of her skirt and instead pulled it up and exposed the fact that she wasn't wearing any panties. I savored this fact as I groaned from her expert mouth on my throbbing cock as I fondled her ass. Firm and luscious it was as I kneeded it with my hands. She began sucking me with vigor, taking me deep into her throat and then bobbing her head like a porn star, making little choking noises before lifting her head to slirp the tip. I was in heaven and it was taking everything I had not to blow my load in her mouth as she gave me the best bj I had ever had. I decided to take the initiative and pushed her ass cheeks apart with my left hand and licked my right index finger before plunging it into her warm pussy. She reacted immediately and began sucking my dick quicker. I honestly almost lost it and filled her throat with cum but I held on. My eyes were on a bigger prize, cumming in her beautiful bald pussy. I finger fucked her pussy vigorously with two fingers now as she sucked my dick, wondering when she would insist on having my cock inside her. She deepthroated me again as I rubbed her clit with my ring finger, releasing her ass as I grabbed her head and shoved my cock as deep as I could down her throat. We held that position for a moment before she tapped my leg and I released her, causing her to come up gasping for air. I immediately withdrew my hand from her pussy and told her I wanted to be inside her. She didn't even blink or speak, she simply sat up and then sat in my lap after I pulled down my shorts. She adjusted herself before plunging my cock balls deep into her glorious pussy. She was tight, warm and wet as I began pumping my cock into her. She moaned louder and louder as I pumped as hard as I could. I knew I wouldn't last long as I hadn't had sex with her sister in weeks but I needn't have worried, she came hard as I thrusted deep. "FUCK!" she screamed as her orgasm hit her hard as I withdrew my cock halfway and slammed into her again. Feeling my own orgasm building up, I whispered into her ear that I was about to fill her pussy with my cum and she spasmed again in my arms as I slammed my cock into her again. She was screaming into her next orgasm as my cum began shooting into her pussy. It was the hardest I had ever cum. I was still shooting my load when she kissed me. I kissed her back as I slowly rocked her in my lap, rhythmically stroking my now half hard cock as I finished cumming inside her. We stayed making out for what seemed like forever before my phone buzzed. We both jumped and realized we needed to get her stuff into the storage unit and get home. I checked my phone as Stephanie got dressed. Sure enough my girlfriend was asking where we were. I felt no guilt as I lied and said that we had to wait for someone to get out of the way so we could get the truck in front of the unit. Stephanie and I fucked again in the storage unit on her couch before we finally decided that I should take her home. I drove her home and kissed her before driving the uhaul back. I got in my car and drove home. Upon my arrival my girlfriend walked up to me and hugged me. "There you are!" She exclaimed. "I thought my slutty sister had gotten you to fuck her." I acted the part as I responded, "Fuck no. What in the hell would make you think that?" "She can't keep her legs closed to save her life. She even tried to fuck my ex." She gave me a look that told me she was figuring out if I was being honest then shurgged and went about making dinner. Later that night we had the best sex we had ever had. Though not because of my girlfriend, because of my thoughts of fucking her sister. Stephanie and I never spoke about what we did again and have not fucked since. I did however manage to fuck my girlfriend's other sisters. If this gets good reviews then I will definitely share them. My Girlfriend's Sister Pt. 02 It had been two months since I had fucked Stephanie. I hadn't stopped thinking about what it had been like. I remember my cock being the hardest it had ever been as it slid in and out of her tight wet pussy. I had seen her many times over the past two months but we never spoke of what we did together. Today is Christmas. My girlfriend and I usually go over to her dad's house and spend the holiday with them. Around five we got ready and headed over. We were the first to arrive and decided to play Pictionary with her 18 year old sister Xaviera and her little brother. Xaviera is a small girl, she has b cup breasts and an ass like Katie Cassidy. She has a flat stomach and long curly brown hair. She wears glasses and is usually the quietest of my girlfriend's sisters. What I didn't know is that her sister had been sneaking their father's whiskey for the past couple hours and was drunk. You couldn't really tell other than her being a lot more talkative than usual. I was her partner and my girlfriend partnered with her little brother. Xaviera picked a card and showed my girlfriend who was the artist for the other team and they set to drawing whatever they had seen. I watched as Era (Xaviera's nickname) drew what looked like a long dick with a set of big balls. I wasn't about to guess that out loud but I could see in her eyes that is what she wanted me to see. She drew more detail as time started running out. She had added cum shooting out of the dick she had drawn and with the way she was drawing it, it looked like it was shooting toward her face. I was now sporting a growing erection and guessed rocket ship as the timer finally ran out. She grinned and nodded her head, "Good guess!" She scooted closer to me on the floor, her sister not paying attention. Era ripped off the paper, folded it, and placed it in the pocket of my button up shirt. She winked and then picked another card. It went on more innocent than before as she seemed unable to find anything she could pervert. Finally others started to arrive. With everyone here I made my move. I got up and hid my raging boner as I ran up the stairs and into the bathroom. I lifted the toilet seat and began stroking my cock. I had my eyes closed and was thinking about Stephanie when I heard a giggle come from my right. From the door. I immediately froze and looked in the direction of the door. Era was standing there in full view watching me masturbate. Her hand was in her short shorts obviously rubbing her clit. "You don't have to get yourself off you know," She said with a grin. She walked towards me and closed the bathroom door behind her. I could hear her father's surround sound start blaring as music was turned on downstairs. "No one will hear us," She said tentatively. She seemed to be losing her nerve but it was only a momentary lapse. She dropped to her knees and before I could say anything she spit on it, coated my cock with her hand and deepthroated my cock down to my balls. She hadn't broken eyes contact and hadn't even built up to taking my whole 8 inches. I stood there in shock. Here I was with my cock down my girlfriend's sister's throat. Era bobbed her head a couple times and gave me a great blowjob, but before I could really get into it she lowered the toilet set and sat down. She pointed to the floor. "Eat your girlfriend's little sister's pussy," She said in a low seductive purr. I acted without thinking. I dropped to my knees and slowly lowered my head to her pussy. I could feel her warmth radiating from her pussy. I could smell the scent of Bath & Body works soap as I drove my tongue in between her pussy lips. I found her hole without any trouble and proceeded to lick as deep as I could. She grabbed ahold of my head and began moaning, but it wasn't enough for me. I slid my tongue out of her hole and up to her clit. I began licking fast and firm. I was in the zone. She moaned louder and louder as I pushed her towards her first orgasm of the night. I could hear the party going on downstairs and wondered if my girlfriend was curious as to where her baby sister and boyfriend ran off to. I didn't linger on that though. I slid my middle finger into Era's pussy and quickly found out that she is a virgin. This turned me on immensely as I began fingering her slowly but not deeply. She moaned and shook harder as she got closer to her orgasm. I took my other hand and slid it up her shirt and under her training bra and played with her nipple. She went crazy. She began bucking underneath me as she climaxed. Not being a man who wasted a moment I got back up to my knees, placed my cock at her entrance and plunged it in. "Oh!" she exclaimed as her first cock was driven into her. I drove it in balls deep and held it there. I felt her convulsing and knew I had made her orgasm become so much better. I knew that she wouldn't really feel much pain if I deflowered her during orgasm. My girlfriend had been the same. As Era came down from her climax, I began fucking her slowly. She was tighter than any girl I'd been with. Even her sister back when I deflowered her. I was in heaven. She seemed to get used to my cock so I began fucking her with all I had. I even picked her up and laid her on the floor so I could do it better. I began slamming my cock into her. She didn't moan or cry out, she simply lay with her eyes wide and her mouth hanging open. I fucked her for what felt like forever when the inevitable happened. I felt that telltale surge of cum. I whispered as much in her ear and she screamed out, "DO IT INSIDE ME!!" That did it for me. I shoved my cock as deep as I could and unloaded everything I had in my balls. I could feel her pussy milking my cock as she grabbed my arms and gripped me for dear life as her second orgasm rolled in. As the dust settled I pulled my cock out. She immediately lifted her ass off the ground in order to keep my cum from dripping out. I thought nothing of it as I cleaned myself up and buttoned my pants and zipped my fly. I stood up and looked down at her. I went to speak but she held up a finger and shook her head, motioning for me to leave. I had raised an eyebrow at her but left. I went downstairs and rejoined the party. My girlfriend was sitting on one of the couches watching Nightmare Before Christmas. She's loved this movie all of her life and got excited when she saw me. She shushed me and patted the seat next to me. She didn't ask where I'd been and simply put her head on my shoulder. Era didn't reappear that night. She had told her dad in a text that she was going to lay down because she wasn't feeling well. We continued the party without her, but I couldn't help but wonder in my now focused mind. Did I get my girlfriend's sister pregnant? To be continued...
