[Poriuretan] My Friend's Little Sister! [Team Rabu2] [Decensored]

Brushed off as an annoying tagalong whenever her brother gamed with his best friend, Fuuka grows up nursing one very specific payback plan—and years later, when that same friend arrives to find his buddy running late, she answers the door grown into a curvy bombshell who offers him barley tea with a smile that promises much more. Slipping off to change into a maid outfit, she climbs into his lap flushed and sweating, breathlessly admitting how happy it makes her that she can finally make him hard. What unfolds is a devoted little sister's long-awaited seduction, turning years of being ignored into her sweetest victory.
