I slipped easily into her wet hole and she gasped as her legs tightened around my back, “OH FUCK YESSS! She cried as my cock slipped in up to the hi...t, Debby continued to grip my balls making it quite a unique experience as I started to thrust in and out, Abi sighing ‘YES’ with every forward thrust.I felt her cunt muscles contract and quickly got into a rhythm, the moans and squelching becoming more intense as I increased the pace, “Go on Jerry, fuck her good” encouraged her mother as Abi.

I imagined her catching me on her bed in an extreme state of arousal. At the brink of orgasm, I felt bold enough to stand my ground and show Mom my enjoyment of her panties. More truthfully, I would be so close to coming that would have to freeze in place, any move causing the light caress of nylon to send me over the edge.
