Brad, Mark and I still hung out every weekend. Brad didn't know that after he crashed in bed three weeks ago, Mark and I stayed up to explore something totally new. Neither Mark not I wanted to be exposed by making the suggestion first, and yet we evidently both wanted it. He, in his loneliness, sought the release of some enthusiastic oral sex, and I was a willing donor - having wanted to try it for years. I was happy to oblige and relieve him of that amazingly abundant load!
In the intervening weeks, it had been a fun secret to share, with Brad being unwittingly a pawn. Mark would stand behind him in my line of sight and grab his bulging penis, raising a brow at me coyly and with alluring suggestion. I knew if we could steal a moment of privacy, he would take his cock out and let me hungrily service it for him. The secrecy was foreplay and he would usually reveal himself fully engorged. When Brad would leave the room, he would show me his prominent boner and whisper "later".
With the extra practice, I could make him cum in only a few minutes, and on Brad's return, be sitting relaxed on the couch with the taste of Mark's offering on my satisfied lips. He would slyly loll his eyes at me afterwards to comment on my performance in secret.

A few weeks had passed, and I was thoroughly enjoying our arrangement. It was a Saturday and Brad was out in the bedroom community visiting his sister's house overnight. It was Mark and I alone. It would be on my mind, so I got it out of the way. "Blowjob?" I asked.
"Yeah, for sure," he hesitated.
"No? That was lukewarm," to say the least. "Is it getting too much?"
"No, it's not that, I love it. Are you kidding? I get sucked and swallowed several times a week? Me and my own hand are getting lazy! No, it's not that."
"O...K. Well, we don't have to if you don't want." I felt disappointed. My mouth watered and I was already hard anticipating it. I hadn't myself grown tired of it yet.
"I do- I do. It's just - is there anything else you want to try?" Mark's voice cracked as he said it. He seemed nervous.
