After years of fantasizing and talking but never doing anything about it, as a couple we finally explored our first adventure into the world of swinging. We are ion our early 40's with 2 kids who are now teenagers which allows us to venture out more.
In January my wife began getting fit and joined our local club here in Atlanta with several other wives where she worked with a personal trainer and in 3 months lost over 30 pounds. She began looking and feeling sexy again. Her personal trainer was in his late 20's very fit, washboard abs with model looks and of course he liked flirting with all the MILF's at the gym. All the wives were hot for him but few flirted with him as my wife tried to on occasion. She admitted that she has masturbated to her trainer a couple of times when she uses her bullet vibrator. I told her that was so wild and hot and she should flirt with him and see where it could lead.
She began wearing tighter aerobics outfits, thong underneath where you could see through yoga pants and sometimes no bra so her nips were rock hard for him to stare at. He got closer to her when she stretched and she pressed back on his cock area to flirt. She loved the attention and she could tell by the innuendos they exchanged several morning sessions as well as catching him looking at her nips and she kept working out in front of him.
She was so worked up one morning when done with her training sessions with the other wives in her group and the hot trainer that she immediately went to the showers before work, but and this time rubbed her clit in the shower as she pressed up against the shower wall imagining it was her trainer thrusting his big cock in her pussy from behind till she came, all the while other women were in either stall showering as well.
She told me about this fantasy when she got home and we immediately took a shower together and I fucked her deep and good while we talked about this fantasy as the water ran over our bodies and I pressed her up against the shower glass and fucked her and I knew she was pretending it was her trainer
I now knew if there ever was a time to do a threesome, share my wife and watch her have sex with another guy it would be now.
