You (Mark) are woken up during the night by the bed rocking and some moaning noises. You realize that your girlfriend is being fucked from behind. I realise you're awake and yell you that it's the American backpacker we had met and let spent the night on the dorm floor. I realise you have a hard on, and start jerking you off while kissing you, I tell you he feels huge. I kiss you while he cums inside me and you cum shortly after from my hand.
