Oh no! My cute little sister, Nino Hikari, is flashing her panties at me!? It seems like she's trying to tempt me by showing a little bit, but she doesn't seem to know when to stop... Her thighs and butt are completely visible, and I'm fully erect!! Being aroused by my sister's panty flash is so embarrassing... "Onii-chan, did you get hard from looking at me?" she teases with a smirk. My sister's seduction escalates as she pulls down her panties and inserts my penis!! She looks so good in it! Nino Hikari's first full-fledged school uniform work!!
