The fact that Penny's boyfriend found out she's been playing with the nerd has just gotten Sheldon a black eye. As Penny attempts to tend to Sheldon's wound, Amy's knock on the door interrupts her. Penny tells Sheldon to hide since she is unaware that he is there. Amy, it turns out, has come with a skintight dress for each of them to wear as she takes Penny to the comic book convention. Sheldon observes as each of the girls gets undressed and puts on her clothes. Just in time for Amy to hurry them both out the door, he announces his presence. Amy tells Sheldon that he has a tough appearance with his back eye after they return from the convention, and she even gives him a lengthy kiss to prove it. Amy presses Sheldon down onto the couch so she may kiss Penny with the same fervor because she loves how Penny looks in spandex. Amy notices that Sheldon is stroking his cock while he watches the females make out, so she goes down on her knees and begins to demonstrate the technique she has been learning. She offers to share with Penny, and before long, Sheldon is receiving head from both girls. Amy is eager to share everything, even if it means fucking Sheldon jointly. Naturally, she has the first go, but Penny quickly finds herself straddling Sheldon's fuck stick. Amy eventually finds herself completely pushed inside with Sheldon and her face buried in Penny's snatch. Penny's lips opens up another hole for Sheldon to add to his array of objects to fuck when she scoots forward to execute a pseudo-69. Before the females kneel next to one other and receive a double facial, Penny has one final intimate experience with Sheldon's dick.
