Here I was, with a major stiffy, in front of my hot little sister, both of us now clean, fresh and nude (with the exception of her wet orange thong). I kept thinking about the odd expression she'd had on her face when she got me to promise not to enter her.
"Listen, kiddo, about that promise you blacmailed your poor horny big brother into.... You know you can trust your loving big brother, but it really was a treacherous thing to do. You're just as horny as I am! Those marvelous breasts and that fine ripe ass of yours sure seemed to welcome my touch; and when I was so extra careful to make sure that your thong was rinsed thoroughly, front and rear, I didn't hear any complaints."
She pouted adorably once again, and stared at my raging cock. With a suspiciously naughty smirk on her kissable lips she said, "Brothers and sisters can't fuck; you know that. Sucking ain't fucking, but anything else would be too nasty for words." She sounded like she wanted to be convinced otherwise. My slim and sexy little sister looked pretty damned hot and bothered herself, from her hardened nipples to the way her ass swayed back and forth.
"That's silly; I shot my juices in one of your holes, and we both enjoyed it a lot. What's the difference between that and juicing in another hole, where you might enjoy it a lot more than the first one?"
"Don't sell yourself short, buddy boy; I really liked the taste of your tube steak. Didn't know your sister was a cumslut, did ya?" She grinned, a really raunchy nasty one this time. "I really get off on the stuff, and yours is prime beef. But fucking is a whole 'nother thing altogether."
I looked at her with all the sincerity and charm I could muster. "You know I won't hurt you, baby girl. But I really want to have fun with you, and I think you want it too. Don't let stupid rules from thousands of years ago keep us apart!" |
