【Screamo】The day I was made to cum by someone other than my husband. ～A blindfolded oil massage that turns your whole body into a sexual zone – 1

I don’t feel anything when my husband touches me, but why do I feel so much when he fingers me? –Mina is an insensitive woman who is having trouble having sex with her husband. One day, her husband’s brother, Katsumi, who is also a masseuse, invites her to a massage where she is blinded by a mask, and her body unexpectedly starts to burn as he loosens her up in the most awkward places. My brother-in-law’s muscular body is covered in oil, and his fingers eventually penetrate my vagina… I’m insensitive, but my husband is here, and he makes me come hard, and I want to go further.
