The big-breasted student pinned down by the instructor

Synopsis

My girlfriend went commando on the street to satisfy my perverted fetish, deliberately seducing the instructor during military training without underwear. I peeked as he pinned her in the bathroom and fucked her hard, her pussy pounded until it was dripping. When a classmate discovered the secret, I had to let him fuck her too to keep it. Watching him ejaculate inside her, I was so hard it hurt. The moment he left, I immediately pounced and penetrated her still-spasming pussy again.
