Her proposed treatment for premature ejaculation involves enduring her seduction and becoming accustomed to sexual encounters.
Confused, he undergoes the treatment, but as expected, he can’t resist Sera’s seductive tactics and reveals his pathetic side.
However, from her expressionless mouth come a series of affectionate words such as “cute” and “I love you”…
