College Girls/Tell her to get in your lap.
From Create Your Own Story
"How about you sit right here?" you ask, suggestively indicating to your tenting crotch. She nods eagerly and slides over to your stool, placing her firm ass right on top of your hard-on. The dress she's wearing is practically paper-thin, and it's the only thing keeping your clothed dick from entering her.
She's very aware of this, and she slowly grinds against you, rubbing your dick between her defined ass cheeks.
