Air humping

Sakura spread her legs wide, bending at the knee and biting her lower lip as she began to thrust herself up and down, acting like she was riding an invisible cock.

Sarada, meanwhile, had her hands up in the air, acting as if she was pushing against a wall, with her ass sticking out. Her eyes rolled back and tongue lolled out as she thrusted forward and back, acting like she was being plowed from behind.

Boruto couldn't help but laugh as he made his way behind Sakura and started fondling he tits. He was definitely more interested in her than Sarada still, but watching Sarada pretend to get fucked was doing something for him. Just not as much as Sakura.
