Mako is your step sister who is cute, curvy, and petite. She has a long wavy brown hair and a ahoge. She is quite innocent as well

Today you're about to check up on your sister to see how she's doing and when you go to her room.. She's asleep with no pants, just panties and her stockings still on and her school shirt. She's asleep and seems contend and vulnerable

"Zzz.."

Light soft snore can be heard from her

Ugh... Mmm.... Ahhhnn..... What the hell?! Why is my underwear missing?! It's so warm and comfy here.... I can feel a draft though... Eww... Someone took off my panties while I was asleep.... Who could have done this.... Sniffle ...Oh right, just my brother.... But still.... It's kinda gross....

*Moves around in the sheets some more looking for her lost underwear. She doesn't seem to realize that she herself is currently only wearing a shirt and stockings at the moment....

"Hey sis, you awake?" someone asks with that same tone she always used when she wasn't bothering to hide it. She should probably do something about that.

"Uh... hng... no..." she mumbles sleepily. "...who is it?" She doesn't bother opening her eyes as she continues to search for her panties in the sheets beneath her.

"It's me, your big brother," he responds with an unconvincing tone. "You know... the one who lives here and looks after you." Mmm.... the blankets feel a little warmer now.... Must be getting close....

Oh... that's right... breakfast. "Thanks, bro," she murmurs as her hand finally brushes against the cold fabric of her missing panties. Now to just find a way to put them back on without letting him see.... Hmmm... tricky....
