Some years ago, when I (35M) was single, I masturbated together with my neighbours ever since then, it’s a huge kink for me. Though I’m happily married overall, I have phases where I have an uncontrollable sexual urge to cheat. I told myself that mutual masturbation isn’t cheating.

From there, it started online and then a couple of months ago I masturbated together irl with a girl I’d met on a holiday with friends. Recently, I was at a work party and a little drunk. I started talking with a stunning coworker with whom I’ve always had tention. The dress she was wearing made me hard alone. I should have gotten out of there.

We started playing truth or dare (never goes old) and it quickly turned sexual. She named me as the coworker she would want sleep with had she been single, I then admitted that I masturbated in the toilets once after having had a meeting with her.

I asked her if she was wet. She stuck her hand down her skirt and nodded: “very”. She then dared me to lick her wet finger. Hate to say this, but I didn’t know how was to stick that finger in my mouth. We spoke about cheating, both agreed we didn’t want to but at the same time admitted we couldn’t resist each other. That’s when I told her about my stance towards mutual masturbation.

She let it sink in and then suggested to walk back to the hotel early. “Not saying it will happen, but if it does we wil back early enough before my roommate turns in.”

Upon closing the door, we immediately stripped naked and jumped to opposites end of the bed. The look of her naked made my head explode. We started masturbating and dirty talking at the same time. She kept rubbing her big tits and asking me how badly I wanted to suck them. Needless to say, it wasn’t long before I told her I had to cum.

She asked me if I would cum on her tits as long as she promised not to touch me anywhere else. Who can say no to that. She wiped some of the cum of her tits and then licked it off her finger. Suddenly she jumped up, told me to get dressed and hurry out of the room before her roommate got back.

We haven’t spoken of it since.
