25-year-old Kanna, two years into marriage, an E-cup housewife with no children. After a part-time shift, slightly tipsy, she visits an esthetician. Bored with married life, she hasn't tried to conceive in about a year and resorts to masturbation at night. She's introduced to a special vaginal care exercise that promises to improve marital relations—immediately piquing her interest. The therapist massages her lower body with generous amounts of oil, then uses fingers to gently rub her vaginal opening, quickly sending her into repeated orgasms from the long-missed pleasure. She straddles the cock from front and back, her wobbling hips strangely erotic. Inserting just three centimeters is said to boost the effect, tightening and training the vagina. "I've wanted to do it with someone other than my husband... But this is just care, right? Still, it's so big..." she murmurs, before gasping as a thick three-centimeter cock is inserted bareback. The direct mucosal contact feels so good she moans toward the camera, "The dick is three centimeters inside me!" Moving it up and down for about five minutes, she trembles with excitement, biting back moans of "Ah... ah..." as she resists the urge to take it deeper. When asked if she wants it fully buried, she instantly demands pounding thrusts, climaxing recklessly with a creampie. Stimulated on her nipples and clit from behind, her sensitivity skyrockets. "This time, I'll come from clit stimulation too~" she whimpers, giving a delicious blowjob before crawling on all fours, begging for more. Doggystyled hard, she gushes a year's worth of cum in powerful squirts. "No, it's too much! I'm squirting so much~" she cries, the wet slaps echoing as she explodes again in cowgirl position, her lust fully unleashed. They mutually satisfy their desires, finishing with another sticky creampie that seals her pregnancy. Finally, loads of thick semen are splattered into her mouth and all over her face. Trembling, she says, "I think my skin feels a little smoother now. I really love sex◆" clearly satisfied. Kanna leaves completely fulfilled by her vaginal care workout!
