EBWH-365 · I Asked My Gentle Sister-in-Law to Let Me Drink Her Breast Milk... Fumika Kashiwagi

During summer vacation, I'm staying at my brother's house, helping out with the kid since he and his wife are both busy working. My brother's wife, Fumika-san, just returned to work after maternity leave, but since they're still anxious about leaving the baby with strangers, I ended up taking care of the little one.

Fumika-san is incredibly beautiful and kind; honestly, I'm jealous of my brother. She's just a bit airheaded, or rather, she has a clumsy side to her.

Even right now, she's like that. Despite me, her brother-in-law, being in the same room, she's lifting her clothes and breastfeeding without a care in the world.

"My breasts have been so full lately... they're practically bursting~"

She doesn't seem to notice my gaze stealing glances at her breasts at all.

My arousal 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, my days of gulping down my sister-in-law Fumika-san's breast milk while fucking her like crazy began.
