mm-gou's new project! We approached two modern college girls who seemed close and guided them to mm-gou! The two best friends challenge an escape from a "sealed room where you can't come out until you accumulate 20ml of semen" by reverse-picking up a Showa-era-raised old man for a high prize! While being bewildered by the old man's overly energetic, super dick that is older than their fathers, they use double kisses, double handjobs, and double fellatio to cooperate and make him ejaculate! The modern girls squeeze out the Showa old man's sperm until it's exhausted with an all-around simultaneous attack! In the end, double creampie with raw insertion into the two pussies! Harem reverse 3P!
