Ménage à trois.

Lindsey and Brigitte frowned and let out sighs of disappointment, thinking Frank was flaccid after cumming inside Katy. But much to their surprise, he pulled out of the young doctor's pussy with a raging hard-on.

"Xentrex is amazing," he laughed, reading their thoughts.

"So who are you going to fuck next?" Lindsey asked.

"Both of you," he replied with a grin.

"Ménage à trois?" Brigitte wondered.

"I couldn't have said it better myself," Frank chuckled at the fact the French had an eloquent phrase just for such an act. "Sweetie, please lie on top of Lindsey."

The brunette stared at him for a moment before realizing what he had in mind and rolled on top of the busty nurse. Frank grabbed the girls' ankles and dragged them to the edge of the bed so he could stand between their thighs.

"Oooooh!" Brigitte cooed when she suddenly felt her pussy stuffed with cock. Lindsey pulled her face down to passionately kiss her to silence her cries as Frank started rocking his hips back and forth.

When he felt the brunette's pussy start to spasm, he suddenly pulled out and shoved his cock into the blonde's hungry cunt. He hammered away until she was on the brink of orgasm and pulled out to fuck Brigitte. It did not take long for her to cum and Frank unceremoniously switched pussy. He repeated the process, bringing both girls to multiple orgasms before he finally felt his balls tighten.
