Seduction Game – A Sexy Victorian Bi MFM Threesome Short Story from Steam Books [EPUB ebook] 

The Earl of Stonegate, called the Devil of the ton, and the Earl of Blackvale, known as the Debonair of the ton, have a few things in common. They are both wealthy, dashing enough to make women swoon… and they both want each other. The problem is neither of them wants to surrender to the other and instead of settling the matter with a duel they decide to hold a contest: which of them can seduce the lovely but plain Lady Agnes. May the best gentleman win. WARNING: This 4614-word (about 23 pages) short story is a steamy read that features explicit scenes including bisexual and threesome content in a historical Victorian-era setting and may be too much for some readers to handle!
