Hank gives Gary a reach-around and asks who Gary imagines fucking

"Need a little help, son? Same," Hank said. "I almost never get off just by taking cock." Hank slowly rocked his hips, keeping up his shallow thrusts up Gary's ass. "If there isn't someone in front of me taking my cock, I need a hand and maybe a little imagination."

Lil nodded faintly. Hank had used his hand to get off when she had walked in on Gary and Hank together. It was so exciting, watching them from so close.

Hank slid one hand around Gary's hip and grasped his son's erect cock in his fist. "How's that?"

"Uh-huh," Gary said. "Yeah."

Hank smiled. "I can feel it." He started stroking up and down Gary's shaft. "That's going to work." His hips kept rocking, continuing his steady thrusts. "You close?"

"Yeah Dad, yeah." Gary trembled as his penis swelled in Hank's stroking hand.

Hank glanced at Lil. She was paying rapt attention to the fuck from close enough to reach out and touch them. Tonight had been an eyeful for her, for sure. But she looked happy. She'd been smiling all the way through, whenever he'd looked.

"I always like to imagine where my load is going," Hank said. "Maybe deep inside her cunt. Maybe up his ass. Maybe filling her mouth and running down her chin. Maybe across their faces. You know where your load is gonna go?"

A few breaths elapsed, Hank steadily fucking and jacking Gary.

"Yeah Dad," Gary said.

"Good."

Hank increased his pace, lengthening his hand strokes on Gary's cock and his thrusts up Gary's ass.

"Tell me, tell me who's taking your load. Who is it, Gary?"

*Oh, oh, oh, oh!" Gary hovered on the brink of climax. "Yeah! It's..."

As his orgasm took hold, Gary blurted out who he imagined was taking his cock load.
