She's a total fox and all but she's my k** sister! Anyway, when I told her to take them off I was sure she'd just laugh and we'd go to the party, but ...he surprised me..."Ok," she said softly. Right then and there, without hesitation, she slipped her hands under her skirt and slid her panties right down and stepped out of them. Standing up again, she held them out to me. I took them and could still feel her warmth in the material. She was still facing away from me so I held them up to my nose. Really just a break, this time, but certainly I wasn't going to skip it just because I didn't need it. So I just sat for awhile, entirely untied for the first time today, and tried to gather some composure for whatever he had planned next.I found him in the livingroom, busily attaching restraints to the couch. He put the ball gag back in my mouth first thing, then had me sit down in the middle of the couch so he could clip my ankle cuffs to the straps he'd just put in place. He cuffed my wrists. As I lay in my bed one night I could hear Sally getting nailed by her boyfriend Alan,she was moaning loud and the headboard was banging of the wall my cock was hard and I was wanking it as I listened to her cumming I shot my load and fell asleep.The following day I was in my room listening to music and studying when I heard Sally go into her room, after a few mins I heard her moaning but she was on her own so I quietly went out of my room and peeked in her door, there she was naked on the bed. It was beyond a shadow of a doubt, the best I ever had. And it didn’t stop there. After so many years of being on top, I started to grab her and push her down on the bed. That’s where I go the next shocker. She hopped on top of me and started riding me harder than I had ever been ridden. Hands on my chest and pushing away, sliding her pussy up and down my shaft. Sitting straight up rocking back and forth. And then the clincher of putting her hands on my thighs, pushing as hard as she could with.
