Blurb: Logan and Zara have been married twenty years. Their sex life is boring. Dead boring. They love each other but they want more excitement in bed. The answer? Ask another couple to join them for a very dirty, smutty weekend of darkly naughty sex.
Wicked fantasies and forbidden desires are shared. Girl on girl action? Double penetration? Every dark craving comes vividly to life for an orgasmic weekend.
Author bio: Berengaria is a multi-published author of erotic romance: contemporary, paranormal (magic, ghosts, vampires, fairies, dragons, and werewolves), futuristic, medieval, and Regency-set historical. She loves to read all different kinds of romance so that is what she writes: one man/one woman; two women; two men; two men/one woman; three men, two women/one man, three men/one woman…. Whatever the characters need for their very hot happily-ever-after, Berengaria makes sure they get it.
