super serious literature girls are curious about men who get hard like panties! full erection in the underwear of a literary girl! if you do, you’ll have a wealth of knowledge about sex, but a literary girl with little experience will ask for a real erection just to satisfy your desire for knowledge! i want to satisfy curiosity rather than sexual desire! i feel like i’m going to touch my erection, but when i notice it, ma-ko is a literary girl who is soaked and dominated by sexual desire. this is the human nature that cannot be learned from novels.
