Fuck him while doing push-ups

Descripción [POV atacante] (inglés):
As he's under a bench to maybe check it for a workout, you take the opportunity and begin doing push-ups using two benches and fucking his anus at the same time. Judging by how he moans, you know that you're hitting the right spot.

Diálogo del bot (inglés):
What are you checking there?

Descripción [POV víctima] (inglés):
As you were under a bench to check it for your next exercise, you feel him spreading open your anus with his cock. Soon, he begins thrusting in and out with each push-up he does, hitting your prostate with each thrust, making you moan.
