He fucked both girls.

If Eileen thought she was going to a receive some respite from Frank's lechery when he pulled out of her pussy and turned his attention to Katy she was mistaken. He motioned the redhead get on top the brunette, with their large tits squished against each other and their wet snatches inches apart.

"What is he going to do now?" Eileen asked the obvious.

"He's going to fuck us both," Katy replied before letting out a not so feminine grunt when Frank jammed his cock deep into her cunt in one quick stroke.

Eileen had experimented with lesbian sex back in college but always preferred having a real dick or two in her. She never had another woman on top of her while a man fucked them both. The look of the beautiful doctor's face in erotic ecstasy while Frank banged her from behind made Eileen more wet. When Katy let out a cry as she started to climax, she pulled her head down to give her a passionate kiss.

From his angle Frank could not see the two girls kissing but he could imagine it and that got him more excited, pounding the doctor's pussy harder and faster until her body stiffened as her orgasms overwhelmed her. As tempting as it was to cum in Katy's quivering pussy, he wanted to fuck both cunts as long as his endurance could sustain.

"OH GOD!" Eileen cried out when she suddenly felt her pussy filled and stretched by his massive cock. Katy silenced her moans of pleasure with a fierce kiss.

When he brought one woman to orgasm Frank unceremoniously pulled out and started hammering away at the other's pussy. They lost count of the number of times the girls came but the bedsheet was soaking wet with bodily fluids. But despite his exceptional physique and experimental ****, his stamina had its limits and Frank eventually needed to cum.
