I'm a married male, 39, and my wife's cousin is a 23 y/o very fit ex-soccer player. she graduated college in April (on a soccer scholarship) and has been looking for work but finally found a retail job recently. Over the last couple of year's we've exchanged a few "hey you look good" comments but I've never thought anything of it.
Xmas day her and her family come over. She is staying the night bc she is working the next day close to our house. Come 9pm, everyone leaves and my wife goes to bed with a headache and we are just watching the basketball games on tv. She starts complaining about having sore feet so I offer to rub them. I honestly didn't think anything of it until she sits up and asks me to rub the inside of her thighs. Now i'm starting to get hard and she notices. She moves my hand towards her pussy and reaches over to rub my cock from the outside. The whole time we are watching the game and don't make any eye contact. Finally, I turn around and pull down her pants and go down on her. Her pussy tastes amazing!! Tight, pink, just perfect. After about 10 minutes I spread her very athletic legs and fuck her on the couch. She starts to get loud so I cover her mouth and I've never been turned on more in my entire life. I finally get close to the end and pull out and come all over her stomach and tits. She says "that's so hot" and smears it around on herself.
We go and clean up and she just says "good night" and then goes to bed and leaves for work the next morning before I wake up. Haven't heard anything from her since. I have jacked off about 6 times since then thinking about it!!
