I received a package from my sexless and frustrated mother-in-law, Eri. When I opened it fearfully, what was inside was erotic underwear and a vibrator. Eri uses it without doubt in the letter that she is a free monitor. However, it was actually a trap sent by her son-in-law, Hideki, who wanted to make Eri's big breasts his own. Hideki, who was filming the situation, approaches Eri's body!
