In her third year of marriage, young wife Tsumugi Narita asks a virgin man for help learning about sex. With her serious and pure demeanor, she uses her skilled blowjob techniques, licking and sucking his shaft until his virgin cock is on the verge of erupting. To practice intercourse, they start with outer course training using a vaginal pad, then proceed to missionary position, stimulating his glans directly to prepare for real penetration. Eventually, they achieve smooth, bareback penetration, leading to an eventful and passionate encounter. Deeply moved and emotionally stirred, Tsumugi gently allows him to creampie her.
