NHDTB-996 - Her older sister with large breasts is calmly pressing her bare buttocks against someone inside the kotatsu, enticing and attempting sexual intercourse; a hyper-sexual 'loss girl'.

The older sister I met for the first time is a 'loss girl' akin to a NEET. I thought she was introverted, but she acts boldly once she gets into the kotatsu. Even with her nearby, she reaches for my genitals and slaps my hand! While hiding in the kotatsu, she inserts herself! She pretends to be calm while pressing her bare buttocks against me, enticing and attempting sexual intercourse! She seems to have been suppressing her sexual desire for a long time, and she went for a second round with her without her knowing!!
