Jane wished her mother allowed her to wear thong underwear but upon asking, it became obvious this was completely out of the question. She still had the outfit at Jill's house and she would wear that every time she was over there. Unfortunately she was home more times than not.

Jane had discovered an alternative. She wouldn't wear any panties. She rationalized her mother couldn't possibly find out and the thrill of not wearing panties excited her tremendously. If the opportunity was there, she would wear a sweatshirt and not wear her bra either. It almost made her feel nude when she only had on outer clothes and had no underwear underneath them.

She was also discovering the feminine art of teasing. She took great pleasure in changing her clothes and leaving her door open a crack. She could watch in her mirror as her brother would sometimes stand in the hallway and watch her. She was careful, however, to do this only when she had panties and a bra on. Although "being seen" aroused her, she wasn't ready to allow her brother to see her nude yet.

She kept the ring she had bought for Mike hidden in the back of one of her drawers. She took it out and admired it. She couldn't wait to give it to him but although they talked on the phone every day, she hadn't seen him in almost two weeks. Luckily, her parents were going out on Saturday night and she and her brother were to be home alone. Her brother had readily agreed to have Jill and Mike come over after their parents left.

On Saturday evening, as her parents went out the door, Jane ran to her room to get ready for Mike's visit. Although not intentionally, she had left her door ajar and as she took off her blouse, she saw her brother's reflection in her mirror. He was in his usual spot watching her. Feeling more adventurous than normal, she ducked out of her brother's view and quietly went to her door. She quickly swung it opened and saw her brother's shocked look.

A guilty look replaced the shock as he knew he had been caught. Instead of yelling at him as he expected, an evil grin formed on her lips. "If you're gonna watch, the least you can do is get your clothes and change in here so I can watch too."

Ken's guilty face turned into a happy one as he went to his room and grabbed his clothes. As he tossed them on his sister's bed, Jane pushed her jeans down and stepped out of them. She stood up dressed only in her underwear as her brother removed the jeans he was wearing. He reached for his clean jeans. Jane, still wearing her evil grin, said, "Bet Jill would get a thrill if you weren't wearing any underwear."

"Huh?" her bother mumbled as he quizzically looked at her.

"Let's make it a 'no underwear' night!" she suggested.

"You serious?" Ken questioned.

"Yup," she gushed. Reaching behind her, she unhooked her bra as she boasted, "I'll prove it!"

Her brother watched in amazement as Jane let the bra drop to the floor. She made no attempt to cover herself as she hooked her thumbs in her panties. She hesitated and looked at her brother. "Well? You chicken or what?" she teased.

The same evil grin on Jane's face formed on Ken's as he unceremoniously shoved his underpants to his ankles. Jane gasped, not with embarrassment but rather excitement as her brother's hard rod slapped against his stomach. She dropped her panties and stepped out of them. Proudly displaying her nudity, she commented, "Looks like you're glad Jill's coming over."

The two stood for a moment and stared at each other. Jane felt the tingling start between her legs. She was pleased her body had such an affect on her brother. She took a new pair of low slung jeans from her drawer and slipped them on. Her mother had not realized the style when she bought them and had let Jane keep them rather than admit the mistake. As Ken pulled up his jeans over his nudity, Jane held up a short jersey and a button front shirt. "Shirt or jersey?" she asked her brother.

"Jersey," he answered. His hormones overriding his mouth, he added, "It will show off your nipples better!" Jane smiled as she pulled the short jersey over her head. Her nipples, hard and protruding with her state of arousal, jutted out under the tight fitting material. She looked up to see her brother staring, a wide grin on his face.

A knock on the door announced Mike and Jill's arrival. As Ken put on his shirt, Jane ran to the door and let the siblings in. After a brief greeting, Ken came into the room. Now was Jane's opportunity to give Mike the ring. She grabbed his hand and, leaving her brother and Jill in the living room, led him to her bedroom.

She had him sit on her bed and close his eyes as she pulled the ring from it's hiding place. "Its beautiful!" Mike exclaimed as he slipped it on his finger. He pulled Jane to him and kissed her deeply. As she melted into his arms, she mumbled, "I've missed you."

Things progressed quickly as  hands roamed over the other's body. Jane's arms rose as Mike pushed her jersey over her head. He left her to pull the article from her arms as his lips went to her hard nipples. She moaned as he suckled them. His hands quickly went to her jeans where he fumbled with the button and zipper. As he finally conquered them, Jane raised her hips allowing the garment to slip down. A finger easily slipped into her oozing pussy causing her to gasp. "I want you," she groaned.

He stood above the nude girl, removing his clothes and putting a condom on. Jane's legs spread as she anxiously awaited his rod. He positioned himself between her legs and she grabbed his cock aiming it at her longing box. He slowly pushed shoving his spear into her tunnel. "Yesss," she moaned as her legs went around his body trapping him in her cage. As he started pumping her, groans emanated as her itch was finally being scratched.

Jane cried out as orgasm hit her hormone raging body. Mike kept pumping causing Jane's plateau to rise even more. Her ass was hardly hitting the bed before her hips would once again jut up to meet Mike's plunging cock. A twitch of his cock told Jane he was about to cum. Mike pushed into her hard as his cock erupted. Both were breathing deeply as cum spurted from his rod. The afterglow of ecstasy enveloped them as their climax subsided.

Mike stayed on top of Jane, his softening cock still embedded in her. Eventually he fell out and Jane groaned, still wanting more. He rolled to her side and the two remained in silence. The sounds of heavy breathing and groaning could be heard from the living room. "Let's go watch," suggested Jane with a sheepish grin.

The two nude teens sneaked out of the bedroom and quietly down the hall. In the living room, Jill and Ken were passionately fucking on the floor. Even though Jane had just had her pussy filled with Mike's cock, she started to get aroused as she watched her brother's rod disappear into Jill's pussy. A hand slid in between Jane's legs. She splayed them as best she could as the hand found her freshly fucked but awaiting slit. Her legs started to tremble.

Reaching between her legs, Jane held Mike's hand in place as she slowly sank into a squat. Mike followed her, never losing touch with her dripping pussy. As they watched the sex display from the darkened hall, Jane reached behind her and found Mike's now hard erection. She held it as Jill let out a moan obviously climaxing. Jane stared at her brother's ass as it went up and down shoving his manhood into the writhering girl beneath him. The action caused his asshole to wink at Jane as her arousal continued to rise.

A groan signaled Ken's orgasm. His hips jutted forward impaling the also climaxing Jill. Jane could feel Mike's heavy breathing on her neck. She needed him again. "Should we join them?" Mike whispered in her ear.

"Ya," Jane hissed as she went to her hands and knees and crawled into the living room.

Jill and Ken looked up as they were joined by the other two. "Have fun?" Jill quipped.

"Not enough," Jane answered with lust filled eyes.

"I want to watch you get fucked," Mike said softly to Jane.

Jane looked at him and then at her brother. "You ever fucked a girl in the ass, Ken?"

"No," Ken answered not knowing where it would lead. He hadn't heard Mike's statement.

Jane was so full of lust she didn't care whose cock was where as long as it was in her. She turned and presented her bare ass to her brother. She smiled at Mike and looked over her shoulder. "Enjoy!" she told him as she turned back to Mike to see a large grin.

Even though he had just finished fucking Jill, his soft dick immediately hardened again. He walked on his knees to his sister's ass. Jane grinned at Mike and lowered her head jutting her ass out for her brother. Mike's hand went under her and he started rubbing her tit. Jane felt Ken's cock touch her asshole and then he pushed forward. The stabbing pain made her gasp but instead of protesting, she pushed backwards impaling the cock even deeper into her. Tears formed in her eyes from the burning pain as his cock sank into her belly. The hurt only served to fuel her lust.

Ken's cock stabbed into her as he started to pump She pushed back against every thrust. The burning pain in her ass was quickly transformed into a burning desire. She cried out as Ken's cock jammed deeply in her tender ass. She was on fire. Behind her, Ken was panting as his hips gained speed. Lust was boiling as it pulsed through her veins. She braced herself so she wouldn't fall forward as her brother continued to ram violently from behind. A twitch and then an audible groan signaled Ken's orgasm. Jane felt his cum shoot into her bowels triggering her own climax. Her pussy throbbed as waves of pleasure crashed through her body. Ken collapsed on her pushing her onto the floor, his pulsating cock still embedded in her now raw asshole.

Ken slowly lifted off the prone girl. The movement of his semi hard cock made her wince as it pulled out of the ravaged hole. Jane remained still on the floor. Her hand went unconsciously to her sore entrance as the burning sensation raged. The room that had been filled with groans, moans, and heavy breathing was now silent.

"That was hot!" Jill exclaimed as she broke the silence.

"You think so, huh? Let's see you get a cock shoved up your ass!" Jane grinned mischievously.

"Don't look at me," Ken groaned.

"Looks like you're up!" quipped Jane to Mike.

Mike walked on his knees toward his sister. "You're not going to stick that big thing in me, are you?" screamed Jill in mock terror.

"Bend over, girl!" snapped Mike again with mock sternness.

Mike positioned himself behind the prostrated girl and with one swift motion rammed his erection full length into her.

"Ow!" screamed Jill in pain.

"Oh shut up and take it like a man!" quipped Jane. "Ken, why don't you give her something to put in her mouth to keep her quiet." Ken moved in front of Jill holding his limp dick. She grinned, opened her mouth and took the soft member in. Jane watched with joy as her brother was receiving a blow job as Mike pistoned his cock into the upturned ass of Jill.

The room was filled with Jill's muffled screams, Mike's heavy breathing, and Ken's groans. Cum started to ooze out of Jane's ass. She pushed her finger onto the hole to stop the emission not wanting to go to the bathroom just yet. She didn't want to miss any of the action.

"I'm cumming!" Mike hissed as he shot his load into his sister's ass. Jane watched lustfully as his face contorted with orgasm. Jane spit the still only semi hard cock from her mouth as she grunted. Mike leaned back and sat down leaning against the couch, his eyes closed. Jill also moved into a sitting position.

Jane couldn't wait any longer. "I gotta go to the bathroom," she mumbled as she stood and left the room still holding her asshole. She didn't even bother closing the door but quickly sat on the toilet letting the cum audibly eject from her ass.

Jill appeared in the doorway. "Hurry up! I need to make a deposit too," she urged. The two girls burst out in laughter. The sexual tension that had built up in both of them had been temporarily relieved. The night was still young, though. With their hormonal overflow, both knew it would be a very rewarding night.
