My little sister has a boyfriend! That's fine, but it seems she's a virgin... She's a herbivore and shy, so even though they've been dating for three months, they haven't even held hands. My little sister suddenly came to me for advice on how to kill a virgin... I have no choice, I have no choice but to do something for my cute little sister! I guess I have no choice but to remember when I was a virgin and become her practice partner? By the way, I'm not a virgin (lol)
