The two meet on the train and have sex without knowing each other’s faces or names. It is a Fuyuri manga that focuses on the inside out, including the dildo and condom with semen.
In a world where people are allowed to have sex outside, the two of them have sex on the train going to school.
Time and time again, you’re not satisfied with just letting it out, and you stick to’ filling the vagina with semen’ using dildos and condoms.
It is P46 (including the cover).
