A Different Kind Of Gaming

A few years back, a friend of mine would come over for a "gaming day". He was having problems sexually at home with his wife rarely being in the mood. He knew that my significant other at the time and I were open to a lot of things. What started as us sending him pics and videos turned into "game day". It was sort of code, he'd call us and ask if we were up for a game day and we'd say yes or know. If yes, he'd come over alone. Him and I would play 2 player vs type games, usually fighting games, with my significant other sitting between us. She would watch and guage who was winning, and she would sexually tease that person to tip the balance in the other players favor. Usually it would be in the form of either stroking, licking or sucking our cocks as we tried to play. Normally it would end in a threesome, but if he was in a hurry to get back, I'd watch her make him cum however she chose to that particular time, he would leave, then she would fuck me.
Anyway, one time he showed up with his brother. It wasn't planned on anyone's part. We had agreed on a game day and his brother showed up at his house while he was on his way out the door to come to mine, so he had to bring him. We sat in the same setup, only with his brother on the far end, next to him. We covered the three of us with a shared blanket. The next thing I knew, she was pulling out my cock under the blanket to stroke it. She did the same to him. His brother never noticed, or if he did, he never said anything about it. She made him cum, caught what she could and slammed it in her mouth and swallowed it while his brother was focused on the game. I have no idea how or if he cleaned himself up before fastening his pants back up. Again, she fucked me after they left.
