Sarah, and I were out drinking, and she brought along her boyfriend, Alex. He was so sexy, I couldn't keep my eyes off him. As the night wore on, we ended up back at Sarah's place, and the four of us kept on partying.
Sarah and Alex went to the bedroom, and I heard her moaning from the other room. I felt a pang of jealousy, mixed with lust. Alex came back out, looking for more drinks. I offered to make them, and as I leaned over the counter, I felt his hands on my hips.
"Sarah doesn't need to know," he whispered in my ear. I turned to face him, our lips meeting in a passionate kiss. His hand crept under my skirt, feeling my wetness through my panties. He pulled them to the side, rubbing my clit, and I knew I couldn't resist.
We stumbled into the bathroom, locked the door, and started tearing each other's clothes off. He lifted me onto the counter, positioning himself at my entrance. I felt him push inside me, filling me up completely.
We fucked like animals, the water running from the sink mingling with our sweat. He came deep inside me, and I felt a surge of guilt, but also a sense of freedom. Our secret was safe, hidden behind the closed bathroom door
