On them.

As one of the few men in the resort who the rare luxury to bang Miss Calano, Frank could not pass up the opportunity to fill her pussy with his spunk but Katy's pussy was just as tempting. He had realized after his first threesome that despite his enhanced stamina granted by his experimental erectile **** he still only had one cock to share amongst the women he was banging and jokingly wished he had another cock to satisfy both women at the same time.

"Ohyesohyesohyes!" Eileen cried as she was overwhelmed by another orgasm. He unceremoniously pulled out her pussy and jabbed his cock deep into Katy's cunt.

"OOOOooh God!" the redhead moaned before she was silenced by Eileen's kiss. It did not take long for her to climax again and that pushed Frank over the edge.

He wanted to cum in Katy but greedily also in Eileen -- it came down to primal male instinct of wanting to spread his seed with as many females as he could. So he made a decision just as he felt his balls tighten.

"Fuck yeah!" Frank growled, pulling his cock out of the young doctor and aiming his tip at their wet snatches. "FUCK!!!"

The two women whimpered as they felt what seemed like a gallon of sticky jizz splashing on their pussies, ass cheeks, and even some strands on Katy's lower back for a minute.

When Frank was finally done, Katy rolled off of Eileen and the two of them laid on the bed with their long, slender legs strewn apart, displaying their well worn pussies. They would have drifted off to sleep if Frank did not poke the tip of his cock against their lips. They knew what he had wanted and gladly sucked him clean, tasting their own pussy juices on his semi-flaccid cock.

Neither women were in a rush to get back to work so they cuddled on Frank's big arms for a much needed nap.
