Was she that horny? and just then she started rubbing over his crotch area. We watched side on as she carried on rubbing, you could. Elsewhere around the room couples were engaged in similar activities; one pair were fucking standing up against the wall, a woman was blowing one guy while another furiously fucked her from behind, still another couple were locked in a spellbinding sixty-nine. I couldn’t count the number of people in the room now but the atmosphere of lust and decadence was almost tangible as a wonderful chorus of sound rose from the writhing bodies. Everywhere there was pussy, ass, and cock. Tongues licked,. In her room we stood and the both of us were unsure what to do when my cock started to get hard so I undid my belt and button and pulled down my zip and grabbed Jane's hand and put it on my hardening cock, she started stroking it gently making it go harder and harder. I started to unbutton her blouse and got my first glance at her big sagging tits, I reached round and undid her bra and began playing with them, Jane now began wanking my cock for me and I told her to go down and suck me which she. Handing me one pair she put the other pair on herself as I did the same. She took my hand and took me over to the mirror. As I looked at the two of use we could have been twins. She was blonde to my brown hair and of course she had gorgeous full breasts to my small cleavage, but side by side like that, in matching outfits. I even commented on it. "True, but sisters should never do this" She turned to me and softly kissed me on the lips. Her tongue gently seeking out mine for a brief moment.
