Jun's only pleasure is calling escorts. When he requests a woman named Miyabi who resembles Rin, his former teacher and longtime crush, Rin herself arrives. Shocked but unwilling to turn away the woman he once adored, he gives in. They kiss passionately, and the intense stimulation surging through his cock leaves him unable to settle for one climax, so he extends the booking. Rin considers quitting after a relative discovers her work, but her body cannot suppress its renewed desire.
