Yes

Phil gave one more thrust inside Alex, then pulled out, sliding the slick length of his cock up the crack of her ass just as the first spurt of cum shot from the tip. Haley kept pulling the girl's hair, watching as her sister's back got covered with their dad's sperm, her body shaking in another orgasm. Alex seemed to breathe a sigh of relief out of her nose as her tongue kept lapping at Haley's shaved pussy as she felt her back get wet with her dad's cum.

Haley was still cumming when the final drop of sperm leaked from the tip of Phil's cock, holding Alex's mouth against her, so she didn't notice Alex and Phil staring at each other over her naked body until she straightened up, glancing between the two.

"You felt fantastic," Phil said, reaching out a hand and grasping her large breast. "We'll get you on the pill to make sure I can cum inside you next time."

Alex looked at him, shocked at the idea of fucking him again, and Phil looked at his older daughter. "Don't worry - we'll get you on the pill too. I can't wait to feel what it's like to fuck you, too."

That was when the girls both realized that now Phil had gotten a taste of the **** taboo, he wouldn't stop.
