He fucked the brunette first, hard, her fingers rubbing her clit, until she came on his cock, hard.
The blonde knelt and watched, knees spread wide, hands on the back of her head.
She agreed to this, eagerly, because he promised that she would get fucked next. And that the brunette would lick her while he fucks her. And that she would be allowed to cum as much as she wants, as much as she can, until he cums.
He didn’t specify where she would be licked. She just assumed it would be her clit because she can’t think of anything except her clit after two weeks of nonstop edging.
He will keep her hips lifted off him just enough to keep her clit entirely untouched. The brunette’s tongue against her asshole will drive her insane, his cock pumping in her just so will make her beg as if her life depended on it.
