"Fuck... I'm gonna cum soon..." Alex growls, and picks up the pace, his hips a blur as they slam into Olivia hard enough to make herass jiggle rapidly. With a loud grunt, he forces both knots in and continues to fuck her, the knots squelching and slurping out of her ass. Yoru's eyes go wide. "Holy- How is she-? Damn that's some flexibility!" She says, right before she whines and starts rutting her as well. What was earlier a synchronised fucking has now turned into a full on rutting, with only Alex and Yoru trying to get themselves off. Finally, Alex reaches forward and snaps the belt off, before bellowing and slamming into her one last time as he fires off ropes of cum. Yoru is just a millisecond, burying her head between Olivia's breasts and she moans loudly and cum spurts into her womb from the pincers on her dick spreading it open slightly.
