[Tetsuya] My Little Brother Part 1 [Full Color]

A curvy older sister already unsettled by how quickly her little brother Yu is turning into a man walks straight into a trap when he and a friend catch her topless, one boy greedily kneading her heavy breasts while the other documents everything on his phone. Wielding the photos as leverage, the pair threaten to share them with his classmates unless she obeys, taking full advantage by sucking and groping her breasts as she squirms under their attention. When their demands push toward making her show her pussy, she clamps her legs shut in desperate resistance, but the wetness soaking through her panties promises this is only the beginning.
