Emptied his balls in Katy.

"Don't you want to cum in me, Frank?" Katy pouted as she gyrated her hips around his cock. "I'm the only one you haven't cum in yet!"

"I do, babe," he groaned, "but I just love you girls fucking me..."

"I'm worn out..." Connie sighed, lying on her side to watch Katy ride Frank.

"Me too," Jenna nodded, staring up at the ceiling as she savored her last orgasm.

"Fine," Frank huffed and suddenly rolled Katy over onto her back.

"Fuck me!" the young doctor growled as he flung her legs over his broad shoulders.

"You're going to beg me to stop," he grinned and began pummelling her pussy mercilessly.

Katy pulled his face down to hers to kiss him, muffling her moans, as his heavy balls slapped loudly against her upturn ass.

Frank felt her body stiffen as she climaxed but he kept pounding her cunt despite its spasms around his pistoning shaft. He felt her cum again. Then again and again. He wanted to keep fucking her for eternity but even with his experimental **** he had his limit. When he finally reached that limit he broke their kiss to let out a roar and flooded her womb with what felt like a gallon of spunk. His thrusts weakened until his cock was finally flaccid.

Sally joined the four on the bed in the post-coital cuddle and nap.
