Push her onto her hands and knees on the lounge chair.

Before Katy could react, Frank grabbed her by the arm, spun her around, and pushed her onto her hands and knees on the patio chaise lounge chair.

"What are you...?" the young doctor started to ask but was interrupted when he knelt behind her and rubbed the tip of his cock along her wet pussy lips and clit. Knowing what was about to happen, she realized that she never had sex with a total stranger, at least sober, and the months without being fucked a man in an hedonistic island had pushed her over the edge of the limits of her sexual constraints. She looked over her shoulder back at Frank with lust in her emerald eyes and begged, "Fuck me!"

Women begging for his cock excited him, making him feel like the young stud he once was before he got married and settled down. Frank grinned as he rested both hands on her upturn ass as he nudged the tip of his cock past her pussy lips.

"Jesus, you're goddamn tight, Red!" Frank groaned while he pushed his thick shaft deeper into her pussy. Katy clenched her eyes closed and let out a loud moan of approval as she felt her pussy finally stuffed full of cock meat.

The privacy of Frank's penthouse suite meant that no-one else could see him madly pounding the redhead doctor like an animal in heat and very few people could hear the sounds of her moans and his pelvis loudly slapping her butt. "Fuck yes!" Frank repeated as he, with a firm grip on her wide hips, guided her back and forth along her cock like a well-oiled piston.

"Oh God! Oooh God! OOOOH GOD!" she screamed as her body shivered in her approaching climax. She dug her long nails into the lounge chair's cushion while her pussy spasmed around his cock.

His primal animal instincts was telling his body to cum in the doctor and flood her womb with his seed but the sliver of human logic and reason that wasn't consumed by his lust for pussy reminded himself that the experimental **** he took allowed him to keep fucking her for hours, even ejaculating several times, if his heart could handle it.
