Hank can't stand it. He greases his cock and steps up.

"The hell," Hank muttered. He shrugged off his robe, dug a blob of soft butter from the butter dish on the table, and smeared it over the head of his cock. Feeling himself flush with anger and desire, he stood up behind Gary and Veevee. He'd re-punched his bisexual card with Jim on the cruise, and Gary's rocking butt looked like a big target to him.

"Stay right there," he directed Gary.

"Dad?" Gary said. "Uh..."

"Stay there," Hank said. He put a hand on Gary's lower back. "Bend a little forward."

"Dad?" Gary said. "I mean, uh..."

Hank steered his butter-smeared cock head to Gary's asshole. "Push out."

"Hon, wait," Veevee said. "Does Gary want that?"

Gary's ring softened and Hank's cock head slipped inside.

"Uh!" Gary said.

"There," Hank said. "Now keep going."

"Hon, really?" Veevee said. "Hank?"

"Start your engines, son," Hank told Gary. He gave Gary a couple of taps on his hip. "Give it to her."

Hank's thick cock head stretched his butthole, but Gary was still hard. His cock ached, wanting to thrust and explode. He started rocking, thrusting into Veevee.

"Ohhhh," Veevee said. "Oh yes. Gary hon?"

"Yeah, Mom?" Gary said.

"You okay?" Veevee said.

"Uh-huh," Gary said. "Just want you."

"Oh baby," Veevee said. "Yes. Take me, baby."

Hank followed Gary's thrusts, staying head-deep up Gary's ass, letting Gary take longer and longer thrusts.

Gary's discomfort faded as he kept thrusting. His cock stiffened to full hardness and swelled inside Veevee's cunt. He moaned with the rhythm of his thrusts. Veevee's voice rose as Gary banged her harder.

"Oh baby, yes," Veevee said. "Yes, yes."

Hank's cock hardened and swelled in the tight heat of Gary's ass. His breaths came faster and deeper. His balls tickled.

"Mom I'm gonna," Gary said. "Gonna."

"Let it go, Gary, yes!" Veevee said.

"AHHHHGRRRRhhhh!" Gary groaned. His cock swelled and spurted inside his mother's cunt.

Gary's ass pulsed, squeezing down on Hank's shaft. Tight. Hot. Hank hovered on the edge. Gary's ass tightened with another spurt. That did it.

"Oh oh oh!" Hank said. "Gary, take it, take it!" Hank's hips rocked, thrusting deeper into Gary's ass, shooting cum deep into his son's rectum.
