I'm in a relationship with my coworker, but recently I've been worried that sex hasn't been going well. When I confided my worries to my coworker, Tojo-chan, she advised me, "Girls like the look on a guy's face when he's feeling it! Senior, do you know what feels good to you?" Tojo-chan, who seems so innocent at work, is actually an advanced slut! With the support of my slutty coworker, I've had my nipples and anus thoroughly developed and become more sensitive! Things are going well with my girlfriend, so I'm rewarded by being toyed with by my coworker, Tojo-chan!
