SINN-001 Flight female education! I was in love with my boyfriend, but my uncle took me down and taught me how to use a semen toilet. Runa, 18 years old

``I'm a girl with glasses who studies all the time, but recently I got my first boyfriend!Of course we're in love.But I haven't even kissed him yet, because I want to cherish those things...but... Instead, I have an old man living at my boyfriend's house train me as a ``meat urinal'' without telling him (that's embarrassing...).
