Very hott anal intercourse brought on by an erect penis or three and a surprised anus that will soon feel the smooth stabbing feeling of the penis(es) ripping open their tight anus hole. brought on without consent. often causes internal bleeding and projectile diarrhea.
Those three guys from work were in the stockroom after hours at work when I bent over only to find 3 penises ripping apart my anus hole.
