I sucked his dick while his gf was downstairs.
Every time our little friend group gets together, one of my good guy friends has been doing a thing where we miss each other while everyone is busy. He expressed to me that lately, he loves the thrill of doing something he shouldn't, so I decided to explore that with him.
It first started with us sending naughty messages to each other and we would hang out on occasion (when he was able to get away from his gf)
We took things to the next level the other week when I got down on my knees and sucked his dick while everyone else including his gf was downstairs.
While everyone thought we were preparing snacks and drinks in the kitchen, I was upstairs enjoying every inch of his dick. He told me how much his heart was racing and took enjoyment of using me as a little fucktoy. I am quite a competitive person and so him whispering to me that I take his dick better than gf encouraged me to deepthroat more of his dick. It didn't take long until I received his load down my throat.
We returned to the living room with the snack, acting like nothing happened.
