Let him get there on his own

You smile knowingly, and let the pause drag on, Luke's stuttering dying out after a moment. He turns his head away from you, his cheeks red hot, but to his shame his erection doesn't go down, forming a tall tent against the pillow he has pressed over it.

You cross you arms and keep smiling, waiting him out. It pays off after a few seconds and he turns his head back at you, his teeth grit. "I was...I was pleasuring myself okay?"

"Where you?" You say sarcastically. "I couldn't tell."

He blushes harder and shifts uncomfortably, the pillow still pressed over his groin.
