[HUNTB-462] "Pah...pah...what happened to your pants?" A sister who doesn't care about panchira... But on this day, I washed all my underwear (Censored)

My sister who washed all her underwear and hid her dick with a bandage because she was embarrassed to wear no panties! Forget about that and go as usual, my sister's skirt is turned up and I see it twice! ? When I Asked About My Panties, My Little Sister Said, "You Can't See It," And She Didn't Care At All, But When I Looked At It Because It Was Erotic And As I Expected, I Got An Erection... Moreover, I Thought That I'd Get Caught And Get Angry, But I Got An Erection. My younger sister's adhesive plaster, which began to get excited when she saw it, was in a slimy state. Anything is OK now!
