The MFM combination is the one where the two guys are straight, if anyone's wondering.
My story in the anthology is Between Tooth and Paw. It's the first MFM I've ever written. It's also BDSM, vampire/human/werewolf and it's older woman/younger men!
Here's the blurb :)
Caught between two dominant men until they learn to settle their differences, all Jasmine can do is submit – and enjoy.
Thrown in between the future alpha of all the werewolf packs and the next head of all the vampire clans – the entirely human Jasmine Neal is charged with the task of helping the two younger men to forget their differences and set aside their hatred for each other.
Offering Stafford and Hayden her submission is easy. Offering them her body brings her nothing but pleasure. But she’s only been sent to submit to them for one night. When the council of elders return to discover if their scheme to settle the men’s differences is successful, she knows that the joy she finds with the two men will be over.
Jasmine didn’t expect to find one potential master that night, let alone be caught between two. But, that only makes it harder when she has no choice but to lose them both.
