With a loud thump, you fell backwards, looking up at the crazed girl pressing herself against the reinforced glass door, looking down on you. You had seen her snooping around your house before, but you didn't actually think she'd try to break in. Even more alarming than her crazed expression or the knife she was holding was the massive, almost grotesquely big cock also pushing into the glass.
Seeing your eyes lock on her shaft, something like an electric current seemed to run through her body before she exploded, thick and long ropes of cum shooting out onto the glass. However despite her orgasm, her erection didn't go down one bit, and the mad look in her eyes only seemed to intensify.
It was clear she was going to attempt to get into the house, and it was up to you to stop her. (or not)
