My wife Alice has always been rather average, average looks tits and is OK in bed. For the longest time that's been fine, she still sucks me off if I push for it, but won't let me blow a load all over her face or in her ass.

I (James) work out, am in good physical shape and take good care of myself, leading me to be friendly with a lot of Alice's friends and catch the eyes of a fair few women.

That was fine till Alice got a new coworker, Jess who she introduced me too at a bbq, she was an athletic brunette with a tight body and perky tits. She was late twenties and had a devilish smile, we chatted and talked all afternoon and could even say flirted. We talked workout routines and found out we went to the same gym.

Over the next few weeks we caught up, spotted each other at the gym, went for runs and I could swear Jess wore less and tighter outfits to the gym, and purposely made the hottest noises when working the sets.

Alice knew we were working out, and I started noticing Jess around a lot more, finding reasons to come over, and becoming ever more obvious flirting. She would cheekily tell Alice how hard I had her at the gym, on the weights of course, and how much stamina I had.

Alice started herself wearing more attractive clothes, putting on more makeup and I think she noticed how horny I was getting sometimes after the gym.

Then one night while on the sofa after a few glasses of wine "I know she wants to fuck you" Alice said, as she unzipped my jeans. "She won't stop flirting with you, or wanting to come round, and I know I can't compete" she said taking my hardening cock into her hands. "I don't want to lose you, so I know I need to do something, how about you fuck us both?" She then slide my cock down her throat, only for the doorbell to ring.

I think the idea of the wife being sidelined with her friend becoming my new fucktoy a really hot fantasy, whether my wife is humiliated and has to watch as I pump load after load of cum in and over the hotter younger plaything is up to you
