He pushed her onto her back again and spread her legs slightly. He faintly rubbed his head against her pussy lips and pushed in slowly. A sharp pain w...nt through her body as his cock popped her hymen. He groaned slightly as he pushed further into her tight hole. Blood began to slowly flow out of her pussy as he loosened her up. She sighed with relief as his balls hit her ass, his cock was fully embedded inside and for a few moments he paused there with her pussy muscles squeezing his new. He admonishes me for fighting him so, lets me know that I am only hurting myself and promises that he will leave me unbound only if I behave impeccably. I nod meekly in agreement as I turn my head to the side. It is not my wish to be helpless, blindfolded and tied… He eases his body off of mine and my lungs gratefully expand to take in more air. I do not even care to flinch when his fingers unlace the slender ribbons of my blouse. He pulls it low around my shoulders, over my arms and bunches it. . They're just... pleasuring each other... " It is a SIN! he cried as his sister began humping his fully hardened cock with her mouth."Looks like you like that kind of sin," I said, grinning at him. "Let me guess... Gladius doesn't like any kind of homosexual sex? Even when it's girls doing it?" Please stop, amigo," he groaned as I directed two of my fuck sluts to disentangle themselves from the group and approach Nathan and his sister with eyes trained on her."Oh, come on, Nathan," I said. Most days he had his cock in her throat or cunt. He couldn't get enough.That summer the parents let them go on a vacation and they checked into a hotel and fucked the first thing. They went on a hike in the woods and he sucked on her tits as he finger fucked her. She then pushed her hand down his pant and jerked his cock till he came right there. They thought it was fun finding places to fuck or finger each other. He loved to fuck her on the balcony of their room. They were several floors up.
