[Low] Sucking Time! (Sodachizakari no Kiken na Toshigoro) [Asterie] [Decensored]

When a freezing day sends Minami scurrying home from school, Yoshiki coaxes her under the kotatsu where these sibling lovers quickly decide clothes are optional. What follows is eager oral worship rendered in explicit x-ray detail, a panting confession of love mid-thrust as she rides him to a deep, messy finish. And with permission to stay until seven, one more round is already on the table.
