Yes

Mark eagerly thrusts inside your sex.

"Yes! Harder," you demand. You quickly push your tongue back into Sara's butt while bringing a pair of your fingers to ravage her pussy.

Sara eagerly grabbed Johnathan's ass, pulling his dick back into her mouth. She was clearly used to her size now as he slid into her with much less resistance.

"Such perfect sluts," Johnathan said with pleased admiration. His hands go into Sara's hair as he starts thrusting into her mouth. He takes a moment to admire the sight of your face between the cheeks of Sara's delectable ass. Then he looks further to the sight of your own perfect ass as your Mark's pelvis drives into you. "Perfect combination of assertiveness and submission. I think I may have found what I've been looking for."

"What's that?" Mark asked, curious.

"Something special," is all Johnathan says, continuing into Sara's mouth. Sara's nails dig into his ass, eagerly taking him in.

You pause for a moment to catch your breath, wondering what Johnathan meant by that. The thought is gone when Mark hits you with a particularly good thrust. "Fuck yes! Almost there, Mark! Keep pounding me like that!" Your tongue now goes to lick the lips of Sara's sex once more, your finger now playing with the bud of her asshole.

"Your daughter is so good, Tara. I'm going to fill her belly with my seed," Johnathan told you. Sara for her part was moaning hard on his cock, determinedly breathing through her nose so she didn't have to pull away. Judging by the increasing wiggling of her body, she was close too.

Mark was thrusting at a frantic pace, clearly he was about to cum as well. The thought of all four of you cumming together turned you on so much.
