It was a dark, stormy night. Err, don't all stories start that way? 

Well, it sure was for Naughty. It was high summer so he was already just in his underwear, a pair of boxers. 
He was still a teenager but it was soon going to end. He was all alone in the normally busy flat/place except for his foxy hybrid cousins that were visiting and his grandma watching tv quietly in living room. 

Well, it turned out his female cousin, Angie, is afraid of storms, so after her father left there was naturally only one person to seek out. She was nearly in her early teens and her brother was several years younger. When the thunder stroke she hugged Naughty tight and her brother Matt sat on his lap. He was telling them some stories when suddenly, Matt started grinding his butt against Naughty's crotch and bouncing up and down, doing a little "lap dance". This continued for a while, Naughty not believing what is happening, his cock stiff, embarassed that she'd see it next to him, and his wet spot forming in his undies, he hugs the little guy as he nearly cums all over into his boxers, panting hard, he finds the strength to hug him and out of jealousy she hugs him too and they end up hugging and cuddling for a while, but with anything sexual ceased. Relieved that he didn't actually reach climax but part of him regretting he didn't, he went into his room, started telling his mate over internet connection what had just happened and that he nearly lost his virgnity with his cousin that way. 

Well, he started to imagine what would have happened if he went loose. 

He'd actually shove his dick through his fly, have his cousin remove his shorts and all and start inserting him on his stiff cock with knot fully visible. Because his sis would get jealous she'd start fingering herself and he'd help her out and touch and rub her nipples as she'd get exposed too. Then he'd soon knot her brother's butt, with cum spurting all over...

and that's when he came irl masturbating to the thought and finishing off his excitment. He almost came even through his undies during all the grinding. But he just wouldn't bring himself to and the risk of getting caught was too great for him.

The end....or to be continued?
