I saw her panties, a thing disappearing between her legs. I stood up and walked toward an open door, a bed visible on the other side. Her d****s were ...pen, and other apartments could see, hopefully not too well. I looked out, shrugged, she smiled and we went to the bed. She lay down and I lay beside her. She spread her legs a bit, allowing me to stroke her groin straining to stay within the tight thong. The mound under her thing front was not a camel toe, but more like a large knee, under a. We wrestled to try and gain control over her and in the process we got her vomit on ourselves . The guys were bitching and Mom was going on about another drink , I finally said "Okay Mom , I'll get you another drink , lets just get you upstairs first " We got up on her feet and headed her up the stairs , the whole time the guys bitching and trying not to puke themselves .The further we went the more my Mom started to go limp and by the time we got her to her. .I was in heaven!I told her to relax her throat as much as she could and to just take it slowly. She moved her mouth over the shaft and licked and sucked on the shaft. I loved the way her lips would stick out all pouty like as she moved up and down the shaft. She then moved back up and opened wide again, taking my cock in her mouth. I could feel her relax her throat as she slides my cock down as far as she could. I felt my dick hit the back of her throat then she clamped down and sucked it. There was Frank's car in the driveway but not Mary's. I went into the house, started walking to my room when I heard the familiar bed creaking from Frank's room and his "Oh yeah baby"s. The voyeur in me took over.I went outside the apartment and up to Frank's bedroom window. I peered into the side of his blinds. I couldn't believe my eyes. There was Mary, gripping sheets, her ankles up on Frank's shoulders and Frank pounding his big cock into her. Eyes scrunched closed, mouth open, I could tell.
