After Everyone Decided to Go to Their Rooms I Fuck My Girlfriend's Best Friend

The party ended, the lights went out, the guests shuffled up the stairs. We were left alone on the couch, her and I, my girlfriend's best friend in that short skirt she'd been tapping all night. A second of silence, a look of complicity, and we devoured each other before someone returned for their cell phone. I pushed her against the back of the sofa, pulled up her skirt, discovered that she was wearing nothing underneath and penetrated her with the urgency of someone who knows that time is ticking. His moans muffled by the pillow, his nails digging into my back, the risk of my girlfriend going down for water.
