LADA Decensored — AI mosaic removal version. During summer vacation, I'm taking care of the kids at my older brother's house because he and his wife are both busy working. My brother's wife, Fumika-san, returned to work after her maternity leave, but since she was still anxious about leaving the kids with strangers, I ended up looking after them. Fumika-san is a very beautiful and kind person; honestly, I'm jealous of my brother. She's just a bit airheaded, or rather, she has some scatterbrained moments. Even right now. Despite the fact that I, her brother-in-law, am in the same room, she's lifting her clothes and breastfeeding without a care in the world. "Lately, my breasts have been getting so full... they're just bursting." She doesn't seem to notice my gaze stealing glances at her breasts at all. My horniness reached its limit, and before I knew it, the words slipped out: "P-please let me drink your breast milk too!" Of course, it didn't end with just breastfeeding... From that moment on, the days of fucking her while gulping down my sister-in-law Fumika-san's breast milk began.
