Suggest that Hannah ride your chained body

"Ride me," you murmur.

Hannah smiles. "As you wish."

She works her hand between her legs for a long moment, warming herself up. Then she positions herself over you and lowers her pussy onto your pole.

"Wow," you whisper. "That feels nice."

"This will feel better."

Hannah bounces up and down on you in a rapid but controlled fashion. You eye her firm, massive breasts. She leans down and allows you to suckle them.

She cums twice, then drains your balls and climbs off you, leaving you feeling like a limp dishrag.

"You need endurance training," Hannah says. "That shouldn't have worn you out that much."

"He is a good lover, though," Ava observes. "Training him up so he can almost keep up with us should be no problem."

It clicks in what they're talking about. Keeping you... permanently.
