Daiki is a boy of an age living with his parents, and his mother Yui is very open-minded about sex. His daily life includes accidental upskirt views and glimpses of her breasts, which excite him. One night, after witnessing his parents' intimate relationship, Daiki's desire for sex intensifies, and he asks Yui, "I want you to teach me about sex." To his surprise, she readily agrees. With her big tits, big ass, and voluptuous body, she helps him lose his virginity in a mutually satisfying encounter. That single act of sex turns into an intense, sweat-drenched session as they both give in to their desires. #Captain P
