I, who can't stand wanting to have sex, and my girlfriend, who isn't very interested in sex and doesn't easily consent. One day, our sexual desires swapped! She, who was previously insensitive, lacking technique and stamina, now uses incredible techniques and repeatedly drives me crazy with her prowess! Minami, who has become a highly sexed estrus monster, relentlessly teases my penis! Every day, I ejaculate from her excessively lewd advances!
