Cheating girlfriend caught, punished and creampied

My neighbor came to my boyfriend to ask for a PlayStation joystick. Unlucky for him, my boyfriend was out of the city in a business trip for 3 days already. Unlucky for me, the neighbor heard me having sex with someone the night before. If my boyfriend will find out that I cheated on him, he would be freaking mad. But I knew this guy, he spends evenings playing video games. So he won't be able to refuse, if I will let him fuck me and make him promise to keep my dirty little secret. Fortunately, the guy is cute so I think I will even let him cum inside me...
