Excuse yourself to go to the restroom.

The second she’s out of sight, you’re on your feet, muttering something about needing the restroom yourself. Rebecca nods absently, too distracted by Steven’s latest story to pay much attention. The bathroom is dimly lit, the sound of running water and muffled conversation from the stalls filling the air. You push through the door just in time to see Gemma disappear into the farthest stall. You push the door open just before she can lock it, the hinge creaking just enough to make her jump. She’s leaning against the wall, her dress hiked up, her panties already around her ankles. The vibrator is still inside her, its silicone tip glistening.

The stall is tight, the space barely enough for the two of you. You don’t waste time - your hands are on her in an instant, gripping her hips, spinning her around to face the wall. She presses her palms against the cold tile, her ass pushing back against you, the plug still buried inside her. She lets out a soft whimper as you press yourself against her, and you quickly unzip. Gemma gasps as you push in, her body stretching to accommodate you. The fit is insane - her pussy already clenching around the vibrator, now stretched even further by your cock.

“Fuck,” she whimpers, her fingers digging into the tile. The plug shifts inside her as you sink deeper, the sensation overwhelming.

You grip her hips, pulling her back against you as you start to move, each thrust sending a jolt of pleasure through you both. The vibrator buzzes between you, the vibrations traveling up your shaft, making every sensation more intense. She bites her lip, stifling her sounds, but it’s no use. The stall is small, the walls thin. The sound of skin slapping against skin echoes off the tile, the scent of sex thick in the air. Gemma’s legs are shaking, her body already on the edge again.

“I can’t...” she gasps. “I can’t take it...”

Suddenly, the door to the bathroom swings open, and Rebecca’s voice cuts through the haze of lust.

“Gemma? Are you in here?”
