My sister is amazing, a brunette with light brown eyes. And has the body of an athlete accentuated with girly curves. How I know this? because she use...d to masturbate in front of me.Don't be shocked, it was all her idea; at twelve she confessed her lesbianism. I was shocked but after all it is her life. Things sure changed at that point, she borrowed my nude girl magazines from me, and even masturbated to them in front of me not minding me watching and getting off seeing her body. I guess she. So slowly I peeled off my bra and panties and kneel there in my birthday suit, trying my best to cover my breasts and pussy. Modesty? I had stripped right in front of a stranger. Modesty had gone out of the window. But I still had to try least I go insane.?Drink? the voice said.I didn’t know what to do. The gag was still in my mouth. Was I to remove the gag? How? I was to obey his commands so I slowly moved my hands to the back of my head, all the while expecting to be punched in the stomach. She pressed her middle finger against my anus and it slipped in easily. She began pushing her finger in and out of my ass, with the same frequency as I was fucking Cathy; she added another finger, pressing them both against my prostate. I was straining to keep from coming, when Cathy thrust her pelvis against mine, screamed, and pinned me there shuddering hard, then convulsed against me. I thrust hard several more times burying myself as deep in her as I could and came hard, crying out, and. Oh no! i said and pouted some more, then he hushed me and set the notebook on the desk. do you see what you’ve done to me? he asked me, no longer hiding his big bulge, which was right by my mouth. i looked at it, then i looked up at him, I pointed to the bulge, and asked, i did that?! looking all surprised. yes you did, don’t deny it! oh, i’m sorry, i said, and pouted some more, i so wanted to burst out laughing but held it in. lift up your skirt, he commanded. my skirt?! i asked, pretending.
