Rinako Nishina, a woman in her forties with only one sexual experience—her husband. Moreover, she has only had sex for the purpose of making children and has never experienced fellatio; she's like a natural monument! First, we guide her through her initial fellatio. Her awkward tongue use gradually improves, and as semen is released into her mouth, she says 'somehow, I'm happy' with a blissful face. During her first public masturbation reveal, a male actor barges in, and during sex with the second man of her life, she experiences an unfamiliar position and reaches orgasm. Finally, she enjoys a full course of toy torture and fierce sex with a robust cock, experiencing internal ejaculation and a state of bliss!
