"I have nothing to do! I'm too bored..." Haven't you ever had an experience like this on a company trip?! When some horny old men try to play a prank on a plain girl by mixing her body with an aphrodisiac... she turns out to be a hidden big-breasted pervert! When they offer their dicks to her, saying "Sachiko is so sexy," she licks them... she's just the right kind of woman! With boobs fondled and a line of people waiting to get fucked, it develops into a sweaty orgy! Ah, the ahegao face of the girl with glasses is the best!
