A solution

The unseizing pace making your pussy sting and twang making you wriggle trying to get away from it. Clearly irritating the attacker as he reefs at your hair grunting as he swiftly pulls out his cock and digs it into your raw asshole.

"AHHH... uuhhhh Fuck" screaming with each pump speeding faster and faster no remorse no end in sight. A moment of hope as you hear noise from downstairs, it hearing as well digging deep into your asshole fearing something rip you scream louder the footsteps rising quickly. Swinging the door open.

The creature pulling out of you walking around standing in front of you its massive cock bathed in its precum and blood presumably from your ripped asshole. Whoevers at the door yelling "How'd you get out" before shining a ultraviolet torch on it as it turned to a plume of smoke evaporating into the airvent.
