START-563 · Used as a Sex Toy by My Husband's Stepson to Relieve His Lust - Koiki Nagisa

It's been a year since I married my much older husband. I live with my stepson and his wife, who was born from his previous marriage. I thought I was happy because the house is spacious and our privacy is respected... but I was wrong! Because my husband and I are sexless, my stepson repeatedly forces me to relieve his lust regardless of the time or place. Unable to resist his thick, hard cock, which is so different from my husband's, I find myself starting to crave him.
