Have them sixty-nine each other.

Of the women Frank had fucked so far at the resort Katy and Connie were the two he enjoyed the most -- their fiery red manes and freckled pale skin were big factors, however, it was mainly because they reminded him of his ex-wife and daughter. That meant he was about to live out a fantasy he knew he could never achieve in reality...

"I want you girls to sixty-nine each other while I fuck you," Frank suggested after pushing himself up and off of the bed.

"Sixty-nine?" Katy paused, biting her lower lip as she looked from Frank's raging erection to Connie. She had experimented with lesbianism with her roommate in college during her undergrad and only kissed the other girls in Frank's orgies but it had been years since she had licked a pussy!

Frank, noticing her hesitation, chuckled and grabbed her ankles, pulling her until her ass was on the edge of the bed. The two redheads squealed of delight and Connie giddily got on all fours over the young doctor.

"Now, lick each other's pussy," he ordered and the redheads did what they were told, each tasting Frank's salty jizz that was still in the other's snatch. He stroked his cock, getting it even harder than it already was, while he watched the two women hungrily munch on each other's pussies. After a couple of minutes of the hot lesbian action, Frank could not take it any longer and grabbed a handful of Connie's hair to tear her away from munching on Katy's saliva-covered labia. The younger redhead wanted to protest but instead let out a low groan as Dr. Roberts twirled her tongue around her clit and with that Frank took advantage of the opportunity.

Katy let out a muffled grunt in Connie's pussy when she suddenly felt Frank fill her own sopping wet cunt with his cock in one swift hard stab. She tried her best to continue licking Connie's pussy while he held her slender thighs wide apart and began drilling her tight cunt with his thick meat pole.

Frank would occasionally stop thrusting and pull out, much to Katy's displeasure, to let Connie lick his cock before inserting it back into the doctor's hot cunt again, much to her pleasure.

"Fuck yeah!" he groaned at the sensation of his cock taking turns inside Katy's cunt and Connie's mouth. He wanted to cum in both of them there and then but he remembering he was off Xentrex he needed to summon all of his willpower if he was to fuck Connie next.

And if on cue, Katy broke her kiss with Connie's pussy lips, arched her back, and let out a scream as her orgasm consumed on. Frank waited for her pussy to stop convulsing around his shaft before pulling out.

"Now it's your turn, sweetie," he grinned at Connie.
