About two hours passed while we slept. I woke needing to piss so I went into the bathroom. I heard the girls stirring in the bedroom and looked out to see Mona with her head between Sharon's legs licking sucking like there were no tomorrow. She still thought it was her daughter.
"Baby you made mommy feel so good let me bring you off too." Sharon just kept grinding her face into her pussy.
"Oh yes do that. Lick me mommy, do me faster."
Stepping up behind her I placed a finger in her pussy then moved it to her ass. I buried it to the hilt as she shook and moaned.
Seeing that she liked this I went to the bathroom and retrieved a tube of k-y that I had there. I returned to the bed and placed some on her ass she kind of jumped when I did but Sharon kept her head trapped between her legs.
"Oh no don't do that." she whined. "I've never had it there before."
"Relax." Sharon chimed in "He's good at that."
"You let him?" "Ok then be kind." "Oh shit that hurts stop." "Ah wait now it's ok I guess."
I had just broken through the ring of her anus and couldn't have stopped if I wanted to.
"Ah mom suck me I'm ready Gawd that is good." Howled Sharon. She crawled out from under Mona. She came up behind me and started to play with my balls. Reaching under me she started to play with Mona's clit and pussy.
I could feel a climax starting at my toes and building to my balls. "Oh shit I'm coming." I called. With that we collapsed onto the bed again.
Sharon went to her purse and took out a weed cigarette and lit it. Taking a big hit on it she handed it to Mona. Mona looked at it in the dark and took a drag. With the booze she still had I figured it would keep her out of it for a while.
Sleeping till about 8:00 I got up to get some breakfast. When I went back to the bedroom I found that Sharon had Mona in the shower with her. "What do you think you are doing?" I ask.
"When she sobers up finding me with her she won't have any choice but play nice." Sharon replied. "Now leave us alone for a while."
About an hour later she came down and said Mona was asleep in the bed. She had sobered up enough to recognize that she wasn't her daughter and started to cry. Sharon had explained that if she made a big deal out of it that we would deny we were together and say she had caught her playing with me and break up her marriage.
Sharon and I went to the pool area and swam for a while. Playing as we did, talking about what had happened. She said it was a dream to have a 3 way with my wife and I but this had been just as good.
I found out that she had been my wife's lover at the same time as she was with me. She hadn't been interested in marriage so she introduced us to each other as just friends.
