A pair of beautiful girls picked up in Sho○ in midsummer. Apparently, the two are friends from college, and both are athletes at a sports university. Minami-chan, who is a shot putter, looks like a gal, but she is a serious and innocent girl without a boyfriend. It seems that her body, which had not been used for a long time, was at its limit, and she quickly locked on to the macho man. When they reunited at night and started drinking at the hotel, they quickly got into the sex mood. She sucked on her favorite macho man's dick as if she was begging for it, and her pussy got wet. Her toned body, which had been trained by muscle training, was pounding hard. She also gave her friend a double blowjob in the middle. Gradually, they got serious and ended up cumming inside her with force. While everyone was unable to hide their impatience at the unexpected situation, Minami-chan herself let out her true feelings, saying, "It's too early to cum inside...". It seems that they had serious sex with the assumption that they would start dating.
