It had been a while since Masao’s mother took him on a trip. Joining the mother and son was Masao’s cousin, Eimi. Due to an unexpected issue, the siblings arrived at the destination first, with Masao’s mother joining the next day. So, Masao got to spend the whole day with his cousin Eimi. Carelessly, he spilled a drink on his pants, and Eimi quickly took him to the room to change to avoid catching a cold. When she removed Masao’s pants, Eimi was shocked—his penis was enormous and fully erect, pointing forward. Having not had sex in a long time and feeling it wasn’t right to leave Masao in that state, Eimi made a bold decision: to let Masao have sex with her!!! All day long, their bodies stayed pressed together, making love, with Masao releasing all that 'bad stuff' inside Eimi.
