Alexi nervously adjusted his cufflinks as he watched Kelly bend over the desk, his heart racing with anticipation. Kelly moaned softly as Alexi's fingers traced along the thin fabric of her panties. This was their first time together and Alexi couldn't help but feel a rush of emotions. He walked behind her, pressing his hardened cock against her ass cheeks. With a gentle push, he drove himself inside her tight hole.
Kelly gasped, feeling overwhelmed with pleasure. Alexi began to thrust slowly, his hips slapping against her wet pussy. She spread her legs wider, arching her back and moaning loudly. The sensation was too intense and she writhed beneath him, begging for more.
As they moved together, their bodies slick with sweat, Kelly felt Alexi's cum filling her up, marking her as his for the rest of their lives.
