Her

She motions you into the unisex bathroom and then locks the door to prevent anyone else from coming in. After doing so, she takes off her panties and shirt and bra, while you take off your clothes. You then sit on the toilet, and then place a condom to cover your dick and motion her to hop on.

She nods and then slowly guides your dick into her pussy for more girl-on-top action. As she thrusts quickly, you would occasionally slap her ass. Before long, both you and her cum, with hers outside the condom, and yours inside to prevent from making any children.

You both put back on the clothes and exit the bathroom.
