I had a session thursday (with a average size black guy TREY) lol. I fucked him so good he didn't wanna cum. He held off 2-3 times and after hh he couldn't come lol. He said he didn't care that was the best fuck! And he had lots of plans for future appointments lol. Holding off can make you not e able to cum. But if done slow and right it can work. Let allison or I know. Teasing your cock sounds like fun!
If done as my client did and go fast and rough and stop yourself a few times it can give you blue balls. If done slow and teasing and the O holds out it could be great
