Of course he does

With a moan, Josh stuck a finger in his mother's butt as he continued to finger himself with his other hand. The alien sensation of having her new prostate stimulated was enough to push her over the edge.

Josh sucked hard and tried not to gag as he felt her twitch and felt the first jet of spunk hit the back of his throat. The taste and sensation proving enough to also bring him to climax. His eyes rolled back in his head as he kept sucking. She continued to shoot streams of hot, sticky, delicious jizz over his tongue. He swallowed hard, not wanting a single drop to go to waste.

They both lay on the cold floor of the bathroom for a moment. Panting heavily and basking in post orgasm bliss. After a moment Crystal rolled off of Josh, finally freeing his arms. He propped himself up on his elbows, wincing slightly as the pins and needles set in. He turned to face Crystal who was laying on the floor, gazing at the ceiling as she came down from two orgasms in a short space of time.

Josh siddled up next to her and rested his head on her chest, enjoying the feeling of it rise and lower in time with her breath. She put her arm around him and pulled him in close. They were both so exausted that within moments, they fell asleep in each others arms.
