She likes to show off

"My girlfriend's a total show off, and thinks it's fun." he sent, and hoped that would fly.

It did, and he got a response, "Would she like it more if I said they were getting me hard?"

Xavier supposed that his fake exhibitionist girlfriend probably would, and sent back "Yes."

"Can I jack off to them?"

Xavier paused, and then sent "Sure." He couldn't help but actually feel a little proud that his legs felt so good, and he looked down, and realized that he was hard.
