Fuck my girl in front of her friend

When I was in high school, we had a party at my house My girlfriend and her friend came over while the family were partying. Me and my girls sneak into my room. Her friend follow us. She asked to used my computer, which at that time it was a Home computer desk. Me and my Girlfriend were horny and wanted to fuck. She looked up both of us and said you guys can do whatever y’all want. I don’t care. You can fuck. You. Can do whatever you want and me and my girl just stare at each other, so we fucked the sideways laying down and fuck my girl and her ass, while her friend was right next to us. If she will glimpse at us. I wonder if she wanted to join it felt so good. Fucking my girlfriend while her Friend was there. I came so hard inside her ass.
