Could it be where the uterus is located?
Even excluding the vagina, the erogenous zones on the chest and abdomen were areas I had already thoroughly rubbed while massaging. Anyway, I stopped exploring my skills and took out my penis for now, but it felt a bit regretful to just masturbate.
Lena's voluptuous body, covered in oil in front of me, was definitely more than enough to tempt me, but my brain, lost in lust, didn't want to be satisfied with just a hand, so it turned its attention elsewhere—her hand.
Lena's clean, unblemished hand. Her hand was slender and stretched out, with pure white, slightly sharp nails growing out. I hesitated briefly. I took my hand off Lena's chest and naturally released the [Sensory Block] effect that had been lingering on my chest. Then, I cast the skill again, this time aimed at Lena's pure white hand. The sensation of blocking was tactile.
