Justin (Vagina)

She slipped into the Janitor's closet and felt something warm go into her vagina and hot liquid burst as well. A moan escaped her lips as she looked up into the guy's face.

It was Justin who had previously been masturbating in the Janitor's closet before she slipped on the water. Justin pulled her in and started thrusting again making Marcy moan louder than before.

She knew this was wrong, her best friend liked this guy but Marcy just couldn't stop herself from enjoying it all the same.
