Mary, a petite college freshman, stumbles into the wrong party, where she encounters Mr. Big Fat Dick, a towering, well-endowed senior. Naively, she thinks she can handle him, but his massive cock proves too much for her tight, inexperienced pussy. He pounds her rough and raw in multiple positions, from doggystyle to missionary, leaving her red and dripping. Mary's facial expression shifts from excitement to shock as she realizes she's in over her head, yet she can't help but beg for more.
