As Teddy felt Gabe's cock start to soften slightly in her mouth she knew she should put this to a stop now. So far tonight she had watched her parents fucking while jilling herself to an orgasm, she had jerked off her 14 year old brother until he shot his jism all over her pussy lips even though she had been dreaming it was her boyfriend she was jerking off, and then to make matters worse she had voluntarily sucked her brother off until he came in her mouth and she swallowed his load to try to bribe him into silence. Sure she had had incestuous fantasies before but never in her wildest dreams did she think she would actually live out any of them.

The problem was all of the above had made her incredibly horny still, her pussy was on fire even though it was absolutely soaking wet. She knew that she should quit now however her physical needs and sexual thoughts were much more demanding than her logical thought processes. Though Teddy Duncan was a sensible 17 teen year old girl - moreso than most of her peers, she often found herself in situations where she substituted long term logical for short term gratification, especially of the sexual kind, even though her logical self knew it would get her in trouble ... and now was one of those times.

Teddy let her 14 year old brothers semi hard 7 or 8 inch cock fall from her mouth. She then licked all over his ball sack lightly covered in hair, before sucking one of his nuts into her mouth again. Teddy had a wee trick she often used on Spencer when she wanted a third, fourth or even sometimes fifth helping of hard cock, and she was sure it would work just as well on Gabe. Teddy licked underneath Gabe's ballsack, she ran her tounge across the sensitive solid fleshy scrotum underneath. She hooked her hands under his knees and pushed them up towards his chest opening his backside up before running her tongue up and down the crack of his arse. She liked how smooth he was compared with Spencer whose arse crack was a little hairy. Then she centred in, focusing the point of her tongue directly at his butt hole, running it around and around. She knew by now he would be hard again, however she wanted him at his peak because she knew it wouldn't take her long to cum, and her best orgasms of all occurred at that exact moment when a guy unloaded his cum inside her.

Teddy pushed Gabe's legs up just that little extra, before drilling her tongue deeper into his hole, literally trying to fuck his arsehole with her tongue. She then pulled away letting Gabe's legs fall back down, and brought the middle finger of her right hand into her mouth. She licked and slobbered over her finger. She then reached up and grasped Gabe's cock in her left hand bringing it down to her mouth. If anything it was harder than it had been before. As she took the young fat cock of her little brother Gabe into her teenage mouth she ran the finger of her right hand down Gabe's arse crack again seeking his butthole as she had with her tounge. When she felt his entrance, without any hesitation she pushed her finger tip in to the first knuckle. His sphincter immediately closed tightly around her finger, so she took more of the cock deeper into her mouth making him focus else where. As he relaxed a little and his butt hole released it's grip on her finger she started pushing it in and out of his arse, while at the same time sliding her mouth up and down on his fuck pole.

She heard Gabe moaning with the double pleasure being inflicted on him. Part of her wanted to go to town on him, forcing another finger into his arse and butt fucking him vigorously while taking his cock deep into her throat. And if she hadn't been worried about him moaning so loud that would he woke their parents she probably would have. Another part of her, specifically her wet cunt, needed to stop so she could get this lovely fat cock buried in her shaven horny snatch. She pushed Gabe's cock all the way to the back of her throat until her nose was buried in his downy pube patch, making sure the full length was coated in her saliva. Then she pulled her mouth all the way off until Gabe's stiff fuck stick fell from her mouth with an audible plop.

Teddy slid up the bed and turned her back to her 14 year old little brother Gabe. She then reached behind her and pulled her brother to roll behind her to spoon her. She took a hold of Gabe's hand and raised it up and placed it under her nightie on her left boob. Though Gabe was amazed at the feel of his older sisters firm titty filling his hand, especially the stiff nipple poking into his palm, he was really disappointed that it looked like his sister had decided to stop the sex play and now only wanted to cuddle, and if only she had kept fingering his arse as he was so close to cumming in her mouth a second time. Gabe needn't have worried.

Teddy pulled her knees up in front of her and soon Gabe felt his hard cock slotted along her wet pussy lips. Teddy then raised her left leg slightly and reached behind her and pushed under Gabe's cock head forcing it up into her wetness, and just as Gabe felt his cock head enter a wet valley Teddy pushed herself down, and in one motion Gabe suddenly felt half his cock buried in the warm purse of his 17 year old sisters wet vagina. Teddy held him there with his cock half buried stretching her suddenly tight pussy lips for a few seconds getting used to the girth of this big fuck meat.

Teddy reached around and grabbed at Gabe's hip and commanded 'fuck me little brother'. Though Gabe had never had sex he knew the basics and so he pushed up with his hips forcing another quarter of his cock into his sister. This caused her to moan and Teddy pulled a pillow towards her and buried her face in it to mask her the moans of her sexual satisfaction as Gabe pulled back and then pushed forward vigorously burying his full length in her. As Teddy moaned into the pillow again she didn't even care if one of her parents heard what she and her little brother were doing even though she knew it was very wrong, at this point no one was going to stop the orgasm that was building from her brothers huge cock buried in her cunt.

Gabe buried his head into his sister should smelling her hair as he humped into her. It was too much for this inexperienced teen, and he groaned into her shoulder as her felt the rush build from deep in his balls. Animal instinct took over and he pushed up trying to bury his cock as deep into her cervix as possible and then he grunted and his cum pumped out of his cock flooding his sister cunt. This was all that Teddy needed to tip her over the edge, her orgasm rocked to her core, and the fact she suppressed the scream of sexually release caused the orgasm to be all that more intense, so intense that her orgasm turned into a squirting orgasm flood out of her pussy over her brothers pussy.

Gabe stayed semi hard with his cock still buried in his older sisters love tunnel, it was obvious they both would have loved to have a second go at it, however the exhaustion of the release they had both felt soon saw them both drifting off to a deep sleep.
