While investigating a damp stain on his bedroom wall, Jerry peels off some wallpaper, revealing a seductive alien orifice growing behind the plaster. After spending an ever increasing amount of time in his bedroom exploring and inspecting the alien creature, Jerry embarks on his first sexual experience. After numerous encounters between Jerry and the creature, it becomes pregnant. Filled with panic and guilt, Jerry attempts to abort the alien creature, leading to a horrific outcome which neither himself nor his mother will ever forget.
