Her mom's nipples are pounded.

Today, Noboru was visiting her house for the first time. She was extremely nervous in front of her mom Nagisa, but as she spoke to her friendly and kind Nagisa, she became completely relaxed and excited about getting along with her and small talk. But that was the time. Every time Nagi moves, I notice that my panties and nipples are visible. She becomes completely obsessed with Nagisa's flashing rhythm... She panicks when she gets angry, but Noboru can't forget that sexy nipple...
