He let it out

"Oh god, this feels great." The men said as he kept humping his dick on the heavenly ass, the sensation is better than simply masturbating.

"I never thought I would actually get to do this." He kept rubbing his cock on the nice butt, as he kept rubbing, he is close to make a release. the legs were trying to kick the man but he is too close for it to have any effect.

"Oh god, I am gonna-" as he said that, he cum as it sprayed onto Blake's ass.

"He-he didn't," Blake thought as she felt something hot on her legs, realizing what the man had just done, and feeling disgusted by it.

"Well, that was quite refreshing." He said as the man look at his masterpiece, his cum is on those beautiful legs and ass. The girl's legs are frozen, not believing that the man had just done what she would think she had done.

Now looking at the ass, he wonders if he should continue on more, he still has some juice left.
