Shaking and moaning she collapsed on top of me, we held each other with my cock still nestled between her soft velvety pussy as we both drifted off to sleep.
We fucked several more times that day, waking each other in some sexual manner. My mother woke me by giving me a blowjob as I slept or by squatting over my face and stuffing my mouth full of her glorious pussy. I would wake her by eating her pussy as she slept or waking up with a raging hardon I would be balls deep in her pussy before she knew what I was doing to her. Either way, we would fuck and go back to sleep.
It was after 6 pm when we woke, knowing that we had to each go to our own homes. My mother got very quiet, during our lovemaking we had not spoken much about what we had done or what we were going to do about our respective cheating spouses. We talked as we showered together, my mother agreed that she would allow me to come up with a punishment for our spouses and that she would go along with anything that I came up with no matter how heinous. I told her that we should go home, act like nothing ever happened, and that within a few days I would call her to reveal my plan of revenge.
It was hard for me that night, arriving home my wife acted the innocent role, putting on her good girl routine. Chris cooked me a nice dinner and even gave me a massage as I watched T.V. I was still feeling a little exhausted from an afternoon of fucking and told Chris that I was going to bed early. Usually I'm a midnight guy, never going to bed, until the late night talk shows come on. Going to bed early usually meaning that I wanted to fuck. Chris came into the room just as I was putting on a pair of undershorts, having just come from the shower. Chris took this as a hint and dropped to her knees in front of me, placing my abused cock in her mouth, she attempted to give me head. I reached down, grabbing her by the shoulders and told her that I was really exhausted and that I wasn't in the mood for that tonight.
Chris trying not to act upset said fine, that maybe we could do something else. I climbed into bed and soon drifted off to sleep. Chris woke me in the middle of the night, my cock had other ideas and was as hard as day old French rolls. She seized the moment quickly climbing on top of me and placing my cock at the entrance to her pussy, impaled herself on it. My cock slightly sore from that days activities, I winced as Chris fucked herself with it. Closing my eyes I fantasized that it was my mother, making the pain more bearable. Bucking wildly back and forth Chris brought herself to an orgasm. My poor cock having nothing left deflated shortly after Chris got off and licked it clean. I rolled over and fell quickly to sleep.
It was during the course of the night that I came up with my plot to exact revenge on my wife and father. I was going to enlist the help of my sister, which I knew she would readily agree to. I would make the call in the morning and once that was done the ball would be rolling.
I hung up the phone with my sister and was surprised at how quickly she had agreed. I told her what happened between Dad and Christina, leaving off how my mother and I had also fucked. She didn't need to know that just yet, and if my plan succeeded she would be able to witness that act first hand.
I arrived at Gina's apartment the next day with the video equipment, setting it up we talked about what she was going to do to seduce dad. She was a little shocked that my mother agreed to the seduction. I explained that mom wanted to shock him with the tape, as she was shocked to find Chris's panties in his coat pocket, and since we didn't know where they went to fuck, that by setting him up I would have evidence to show Chris that she didn't mean anything more to him than a piece of ass. My sister didn't really care about the explanation, all she cared about was that she was going to fuck her father and that she was doing so with our blessings.
My mother received the call on Saturday, she was not surprised since I had explained my plan to her, and she passed the phone to my dad who was lounging in the TV room. My sister recited the story perfectly and my dad called out to my mom, that he was going to Gina's to help her with some electronics.
