I'm a former sports trainer running a massage parlor near a university. Every day, sports girls from various clubs visit my shop after practice. If there's a girl I particularly like, I sometimes invite her to a hotel, though my success rate is moderate. On this day, Erina-chan from the badminton club came in. I carefully massaged her tired body from practice. I was thinking of inviting her to a hotel afterward, but since there were no other customers, I decided to lock up the shop and have some fun right here! Gradually, my hands moved towards her breasts and vagina, caressing her, when suddenly a loud moan escaped her! Was she waiting for this? As soon as I started manual stimulation, she squirted! Erina-chan was so engrossed in enjoying my penis that she forgot where we were.
