A few years ago in an attempt to revive a dying sex life me and the wife decided to explore some exhibitionist ideas. We began with posting picture online and she liked the attention but it didn’t change much for us. She had taken a lot of pictures for this. A few weeks later we were driving home and she asked me to hold her phone. I took this as an opportunity. I sent one of the pictures pretty tame to a mutual friend of ours then followed with an oops sorry. She was at first mortified but he soon sent back fire emojies and said that’s okay you’re sexy. Before I could say anything she had unbottoned my pants and had my cock in her mouth. With a little encouragement she sent him a picture of her in a bra and he replied in a positive manner and she double downed on my cock. We soon arrived at home and I had to run inside with tons of spit running down my balls and a massive erection After getting in she asked me for permission to send him something nude to which I replied why not. She quickly sent him a titty pic and say me down on the couch and climbed on top and started riding me and sending him more each time asking for permission. Nothing overly explicit but she came three times riding me. She got off after the third and told me it was too hard to text and fuck. By this time I’ve got her cum all over my cock and need to blow. She asks to send him my favorite and I say ok as she starts to try and swallow all of my cock while rubbing her clit furiously right on the living room floor and she came again with my cock in her mouth. Mutual friend then reply’s and tells her I’m so fucking lucky she’s so hot and how the last pic made him cum. He was aware I was watching the conversation. She then closed her phone and started sucking my harder and I warned her I was going to cum. In the past this ment her stopping sucking and jacking me off onto her tits and face. This time she just started going faster until I came in her mouth and she swallowed every last drop and kept going a little after I was done just to make sure she got it all. She then climbed onto my lap and said that what we did was wrong but it was so hot to do something so naughty. We both agreed that because of the event their could be no phone privacy between us. Every day we swap phones and go through them even though nothing like that has ever happened again. She says she never wants another man again besides me and it was the “forbidden act” that got her off. She then kissed me deeply and I could still taste some of my cum in her mouth.After years of looking through her phone I know she hasn’t done anything questionable and after this event our sex life was restarted. Went from once a month to 4 to 5 times a week and has stayed there. That friend eventually moved about 23 hours away from us and faded out of our lives. He never brought it up or tried anything, but I am thankful for that event. This is the pic that started it all
