Gaster's dick went in lil hole. She screamed as she was fucked. Gaster didn't stop, he just kept fucking her harder and harder, until she started squirming and moaning loudly, with her body having a hard time telling when he was fucking it or not. The toy had made it extremely sensitive, and soon she was about to cum on the couch, when she saw a familiar object in the corner of the room. She squealed and leapt onto the couch in a fully orgasmic state. "Master! What are you-!" Gaster saw her in the mirror. His expression turned to disgust and he looked at the toy. "This" he said, staring at the futa monster. "This was made for me by the way," he mumbled.
