I just blew it off, figuring all she was doing was teasing me, getting herself off, and I called it good.The previous weekend I'd actually walked upst...airs after Shannon and Karson had gone to bed. Karson was in her room and Shannon was in the guest bedroom. When I walked by, I caught Shannon masturbating. And as she had a massive orgasm, I heard her call my name. I almost came in my shorts. And then almost had a fucking heart attack when Shannon opened her eyes.She was laying there. I could see. OK I said, who's next?.Then it was fair game for everyone to tongue kiss and finger me, even the first couple of guys came back for more as they had missed out on fingering me the first time. I bet you all have giant stiffies, I said, that is just too bad, as I left the room. I went straight to the bedroom and fingered myself to a gigantic orgasm. As the guys were going I heard my husbands three best mates saying, We have known Shirl for years and have never seen that side, or so much of her. Amanda, hesitantly, asked Jessica to show her the "right way" to do it and, much to my shock, within a couple of minutes my dick was massively hard. Lying on the bed, I was watching my step-daughter's head going up and down, as my dick entered her mouth, withdrew, and then went back in her mouth again.I could not believe this was happening.As I gasped, panted and moaned, I knew it was going to happen. I could feel it. My balls were tightening up. My dick was throbbing and pulsing. And I felt. So now I finally got Mom into bed, and with her panties down so far and seeing her hair I just got to see more of her pussy hair now as my excitement grew more every minute with Mom passed out laying there in panties and no bra it was awesome. She was soft to feel and now I was so Horney my dick was hard, this was so much fun, now that I had her on the bed I rolled her to the middle hoping she wouldn’t fall out of bed , seeing her lay there exposed like that was such a turn on I wanted to.
