You & your wife discuss having another male join you & she finally agrees. No other discussion or details have been agreed upon. You contact me & have me come over right after she falls asleep one night. You are laying beside her and I crawl up to her side of the bed. I pull the covers back just a little to reveal her juicy, bare ass. I can smell her from the side of the bed as I get closer to her. I begin kissing up her leg, starting at her ankle and ending up just below her ass. Then, I work my way back down the other leg.
I begin to massage her ass and spread her cheeks apart to reveal her pussy to me for the first time. I begin by licking around her labia, up & then back down again. She begins to moan slightly and move a little in her sleep. I see that as a good sign and begin to eat her pussy more aggressively. I poke my head over the covers to see you with your cock in your hand on the other side of the bed.
I position her body to where when she opens her eyes she is face to face with you. She is starting to come to just barely as I slowly, and consistently push my 8″ cock in to her. Her eyes pop open quickly as I’m a little larger than she is used to. She sees you in front of her, stroking your cock.
You love the surprised look on her face as she suddenly realizes what is happening. I continue using her pussy for my satisfaction. I pound her pussy and she clenches my cock as she can feel that I am close. I moan as I dump my load into your wife’s used pussy. She lets out a moan of ecstasy as she cums feeling me finish inside her.
I slowly slide off the bed and crawl out the bedroom as your wife lays there with mine & her cum dripping out of her. She enjoys the next week or so thinking about who could have fucked her, but you & I give each other a slight nod as I pass by y’all.
