I took her into my arms and told her I had enjoyed her performance on the patio. She blushed and looked down. The lump was obvious in my pants. Justin... will you please fuck me? Right now?" We fucked there, on the floor, with Sondra getting lost in her intense orgasm, and me blowing the biggest wad of cum I had ever shot into her hot, wet cunt. Afterwards, both of us soaking in the hot tub, Sondra apologized for exposing herself to the boys and told me how ashamed she was. I asked her if she was. The next thing she knew the guy behind her was pushing his cock deep into her ass as he came. Very quickly after that, the guy below her in her pussy started pumping his cum deep inside her as well. She could feel someone help her stand, looking up to see two more guys helping her into the bed room. Once in the bedroom she was laid on the bed where one of the two men moved to sit so she could suck his cock, as the other entered her from behind. She didnt know who the guy was, but was feeling. I will shamefully admit that I had been a frequent visitor to my sister’s sweet flanks from the time of her nubile state and we had a secret pact that allowed anal coupling but strict avoidance of any real sex involving contact of our privates in copulation reserved only for husbands or faithful fiancées in complete privacy.At first, she had giggled in that seductive manner that usually caused me to have an immediate cockstand and then she looked me straight in the eye and asked, “Is it all. I always behaved like a dirty girl, even just when using conversation with him. We both discussed everything; it's what best friends do. He knew I was dirty, and I loved that he knew it. I gasped, before shaking my head, 'Stop. Stop.' I whispered, his head lifted from my neck as his breaths panted against my skin. 'What's wrong?' he asked, his face shocked yet dazed. My hand from his neck reached down past his stomach as I tried forcefully to pull his boxers away with one hand. 'Oh...' he.
