The older sister of a single mother had to take care of her niece because she was going on a business trip. The niece, whom I hadn't seen in a long time, had grown into a beautiful girl and was either innocent or careless for not wearing a bra. Even though I knew she was my niece, I couldn't help but notice... After struggling with reason, I couldn't resist touching her exposed nipples... At first, the niece resisted the sudden nipple torture, but after being relentlessly manipulated, she started drooling and moaning! She had developed an early climaxing constitution from minimal stimulation. The niece became addicted to nipple sex and was filled with cum countless times!
