He gives her pussy a fuck.

He got off of her chest, and grinned, stepping off the bed and standing at the edge of it, before leaning forward and pulling the vibrator out of her pussy. He then leaned forward and hooked his hands under her thighs, before pulling her hips up to his, his cock lined up with her pussy. He then moaned as he slid right into her.

He held her legs as he slowly began to fuck her. He was chortling at just how inanimate Yang was being during the whole thing. It would be one hell of an experience for her when he returned her to normal and all the sensations hit her at once. He'd have to cover her mouth though to muffle the scream she'd be bound to let out though.

He sped up, and panted as his sensitive cock kept plowing her unresponsive pussy. He sadly wouldn't be using this trigger all that often, it was fun of course, but he was doing all the work. Her pussy walls weren't even working his shaft, though this still definitely beat normal masturbation. As such, it wasn't long before his throbbing cock spewed out his seed, and after a second to catch his breath, he pulled out, and with a grin, reinserted the vibrator, sealing his seed in.
