This is too good.

Gemma’s eyes fly to yours, her body freezing. You grab her mouth and cover it with your hand, stifling her moans as you continue to fuck her, your hips snapping against hers. Her back arches as you press down on her mouth, pulling her head back. Rebecca’s footsteps echo on the tiles, checking to see if any of the stalls are occupied. The risk, the thrill of nearly getting caught - it only makes it hotter.

“Gemma? I just wanted to make sure you were okay.” Her voice is closer now, right outside the stall. “You looked a little… flushed.”

Gemma’s body trembles, her nails digging into your arm as she tries to stay quiet. You slow your pace, but you don’t pull out. Rebecca knocks on the stall door.

“Gemma?”

Gemma lets out a muffled whimper against your hand, her body clenching around you as she tries to stay still. You can feel her trembling, her orgasm building again, and you know she’s close.

“Well, if you’re not going to answer, I’ll just… assume you’re fine.” Rebecca sighs.

Her footsteps retreat, the bathroom door swinging open and shut again. The moment she’s gone, Gemma lets out a long exhale, her body sagging against the wall. But you don’t give her a chance to recover. You grip her hips, pulling her back against you as you start to move again, your thrusts harder, deeper. She cums in seconds, her body shuddering around you, and you quickly follow her over the edge, burying yourself balls deep inside her. She trembles against you as you empty yourself into her, and eventually her legs give out, her body limp and exhausted.

You catch her and hold her up as she sags against you. You pull out slowly, feeling the cold air of the bathroom on your wet cock. The vibrator slips out with a wet pop, and she whimpers at the emptiness, her body still trembling. You pick up the vibrator and tuck yourself back in your pants, unlocking the latch to the stall and stepping out into the restroom.

"Put it back in," you command, handing her the vibrator.
