unaware giantess has a shrunken man stuck in her asshole

I'm in the bathroom and i just finished showering. i'm talking to my roommate but he stopped answering. i come out with a towel around me and look for him but he disappear. i put on my panties that were on the floor (my roommate got shrunk and stuck on the panties but i don't notice it for the whole video). since my roomie disappeared, i call my boyfriend and tell him to come for sex. i casually fart one time while i talk to him on the phone. my boyfriend arrives and we have sex while roomie is stuck in my asshole (we don't see him). at the end, my boyfriends cums on my ass and covers the poor little man in cum. i go to the toilet to pee and he falls in the toilet and gets flushed.
