During summer vacation, I'm taking care of my brother's kids at his house. My sister-in-law 'Fumika' has returned to work after maternity leave, but she's still not comfortable leaving the kids with someone else, so it fell on me to watch them. Fumika is really beautiful and kind, honestly, I envy my brother. She's just a bit slow, or maybe she's a bit absent-minded. She's doing it right now too. Even though I'm her brother-in-law in the same room, she's flipping up her clothes and starting to breastfeed without a care. "Lately, my tits are so full and swollen~" As I sneak glances at her boobs There's no sign of noticing the line at all. I was pushed to the limit by my lust and before I knew it, I blurted out, "Hey, let me drink your breast milk too!" 」Of course it won't end with just breastfeeding… From that point on, days began of drinking Fumika-san's breast milk while fucking her hard.
