Raised under a strict father, 'Ma-kun' gets caught with a dirty book and is severely scolded. Feeling bad for her little brother, his older sister 'Urumi' decides to take matters into her own hands. She starts giving him 'real' sex education using her own body... How far will her special tutoring go?




















*Nipples that make you want to play with them, nipples that make you want to play with them, breasts that make you want to rub them, I thought it was sex education for my younger brother, but my mother came in, and I thought she would come in and take care of it... Too bad. Narumi-chan has sex alone in the bath, the way she uses her middle finger is naughty This time, I had sex alone in bed, and couldn't resist, so I went to my younger brother. Isn't the foreword a bit long? I guess this is less about sex education and more about relieving one's own frustrations. Sex education finally begins, but there is not much to see. Next is a handjob and blowjob in the toilet, and finally, my brother's night, something is not enough.
This is from before she changed her name, and she's super cute. She's been releasing so many works lately that I haven't been able to keep up with all of them, though...
*I like nipples I think it's good to have a friendly relationship. I think it's cute. It's my type, wow.
*Urumi-chan is cute. It's really nice that the feeling of motherhood comes out so well. The relationship between the younger brothers is not at all flashy, but I feel the depth of the work. Thank you Urumi-chan
*What is this? As for the actor, he has no technique at all. It's obvious. The story is about Urumi, the big sister, giving sex education. However, in this case, there's no way to simply teach him how to have sex. I wanted something more AV-like, like Urumi-chan saying more dirty words, turning into a perverted carnivorous woman, and attacking with amazing techniques. No matter how much realistic sex education is given, the real thing that is taught by a beautiful lady like Urumi-chan is far from reality, and the content is bad anyway.
