Yes.

Mark knows this is wrong. That this is a betrayal with Tiffany. Which is dangerous, because someone can come at any time and catch him holding another dick. It would destroy his life in college.

But, he is so curious, that piece of meat is so attractive, and he wants to see how it gets even bigger. He tries to rationalize and blame his girlfriend for planting desires he didn't know in his head. That he was acting like that just because he was drunk.

He doesn't think anymore, he just acts on impulse. He stretches out his right hand and wraps the black man's cock.

"Hummm, good boy!" The other groans. "It's already growing, you can feel it, just with your touch. Now, jerk me off."

Mark can really feel it growing. As he also feels his own cock to grow in his other hand. He feels the warmth of the two cocks in his hands. He feels the difference in size, in thickness, between the two. The size of the other and the smallness of his in comparison, instead of upsetting him, makes him even more excited with the humiliation. He feels the veins, and the rigid softness of the other cock. He sees the contrast of his white hand wrapping the black cock.

He starts to masturbate both cocks hard. They are both groaning, and luckily, they will not be caught. The excitement is so great, that the two cum quickly.

"Thank you. You have a great hand, but now you can let go of my cock."

Mark had been so excited about everything, he didn't even realize it was over and he was still clinging to the other dick.

The other one leaves, putting the cock in his pants. Mark, still panting, leans against the wall to recover. After washing their cum from his hands, he leaves the bar almost running, without looking around.
