The redhead.

Frank was always a confident man but at that moment he felt an odd pang in his chest -- it wasn't a heart attack but anxiety. He was about to live out a fantasy of many men -- having sex with a blonde, a redhead, and a brunette at the same time -- that probably even few on the island got a chance to encounter!

As much as he wanted to sink his cock deep in the pussies of both the blonde nurse and the brunette concierge, he desperately wanted to fuck Katy again despite having already ravaged her gorgeous body hours earlier. Subconsciously she reminded him of his ex-wife when she was younger, not just physically with the long red mane and freckled pale skin but the feistiness in bed that was unlocked after she had finally accepted her fate with her necklace turning green.

"You two girls keep yourselves busy while I fuck Red again," Frank grinned as he reached out to grab the young doctor's ankles to pull her to the foot of the bed.

"You're not going to fuck us?" Lindsey whined.

"Oh I will, sweetheart, I definitely will!" Frank replied with a deep belly laugh, "and I'll be fucking you so much you'll be begging me to stop!"

"Believe me, he's telling the truth," Katy giggled as she spread her legs wide apart for him. "His prescription will keep him erect and coming for hours!"

Brigitte eyed Frank's raging erection and bit her lower lip before leaning over kiss the nurse and grab a large handful of tit in her hand. Lindsey was momentarily by taken aback by the French girl's sudden and unexpected action, given her uptight reputation at resort, but kissed her back fiercely. The two girls giddily fell back onto the bed and started exploring each other's mouths with their tongues and soft, curvy bodies with their hands.

Both Frank and Katy turned their attention back to each other, their lust-filled eyes locked with each. "I need your big cock in me," the redhead begged.

"And what do you want me to do with it?" Frank chuckled while he teasingly rubbed the underside of his shaft against her wet pussy lips and clit, causing the doctor to moan.

"Fuck me," she pleaded with desperation in her beautiful green eyes. "I need you to fuck me!"

That was the extent of their foreplay -- Frank didn't see the need to continue teasing her given that he was also aching to sink his cock into her cunt.

"Oooooh yes!" the doctor cried out when Frank stabbed his cock balls deep into her tight, hot pussy in one hard stroke. "Oh yes! Fuck me!"

"You love having my big cock in your cunt, don't you, Red?" Frank growled, holding her long legs wide apart by the ankles as he slammed harder into her.

"Uh... Yes... Uh..." the redhead grunted as her large tits violently undulated with each of his thrusts. When he had first brought her up to his penthouse suite she was anxious being used as a fuck toy by a man as old as her father but hours of drilled by his long, thick cock almost non-stop changed her perspective. Initially he just wanted to bang her but she sensed something changed when it became more passionate -- she assumed she reminded him of his ex-wife, more than just physically. They found in each an intimacy missing in their lives for years.

Frank noticed that the other two girls stopped kissing each other to watch him mercilessly pound the young doctor, seeing what to expect when it was their turn to be impaled by his massive cock.

Excited by having a captive audience, he threw Katy's legs over his broad, muscular shoulders so he could lean on to get a better angle of penetration to sink his shaft deeper into her hot, velvety canal.

"OH GOD! Fuck me, Frank!" she cried as she started to climax, her pussy clenching around his pistoning thick shaft. "OhGodOhGodOhGod..."

He was undeterred by amazing sensation of her spasming pussy and continued to hammer away.

"Oh God.. I'm cumming...," Katy cried, staring up into his eyes. His balls drummed her ass cheeks, reddening them, as he brought her to orgasm.

"FUUUUUCK!!!" he roared before his cock flooded the doctor's hungry cunt with a thick stream of jizz.
