[Umekkodo (Umekko)] Kinjo no Onee-san ni Itazura Shitari Saretari Suru Manga (Rewrite) (WIP) [Full Color]

When little Abby's math lesson with her stacked tutor Annie takes a turn, the girl pulls out a game her cousin taught her called "Mommy Cow and Baby Cow"—and Annie's huge, soft breasts become the prize. What starts as curious squeezing and groping melts into a tangled sixty-nine of mutual nursing, Annie's soaked panties betraying just how much she loves the tiny mouth latched onto her leaking nipples. As Abby suckles harder and Annie's hips arch on their own, the flustered tutor teeters on her very first orgasm, wondering exactly what kind of pervert this makes her.
