Its short, like 10 pages, black and white comic.
One girl wakes up, starts making breakfast, another aproaches, gets a vaginally attached strap on and fucks her, creampies her, becluse apparently that stralon has balls and can do so, and then that girl who was fucking her hugs her from behind when she is still bended over, with her head (specificallly chin) and chest laying on her back.
Then another girl comes and she passes her the strap on, and the girl is fucked again, the comic ends with a scene of the same girl being fucked yet again, bebd over the table on which another girl eats her careal.
I assume it happens in some hind of soriority, or at least the girls live together, i also kind of have vibe form the coments below said doujin that these characters were from skoe kind of game, like novel or arknights.
I am sure i saw it once on r/FreeuseHentai or r/hentaiforcedorgasms or on r/helplesshentai but i searched throught these subreddits and cant find it now.
