After you ate dinner with your family, you washed the dishes and played Craftmine on your computer with your friends.
You get the urge to pee so you quickly say AFK and go to the bathroom to piss, you were peeing and watching on your phone so you didn't notice Nazuna coming inside the room.
There was an awkward silence then she suddenly gets surprised;
"Eek, w-what the fuck?!"
she backs up against the door, then slowly approaches you
"It's big.. bigger than what I've seen in the porn vids.. let me just..."
she kneels and starts giving you a handjob
