At work, a kind, busty senior colleague imparts sexual knowledge to a newly hired junior employee (a virgin) through naked penetration! A game of 100,000 yen per shot while blowing on a calligraphy brush! This time, our challenger is "Jun-san (27 years old)," who works in sales at a clothing company... He has a model-like appearance and is very charming in his comfortable Kansai dialect. He leaves her alone with her subordinate. Jun-san smiles and gently leads the way, enjoying the virgin's reaction, but that time is short-lived... The piston-like force of the bottomless virgin's desire explodes, he convulses, and reaches a severe orgasm! "No ejaculation inside!" he orders with the authority of a superior, but the virgin boy can't stop shaking his hips, eventually ejaculating a large amount into his superior's shaved vagina♪ Afterwards, he is completely immersed in pleasure and finally says voluntarily, "Ejaculate inside the vagina." *All performers in this work are adults aged 19 and over.
