The Cuckold and the Fireman — Nancey Cummings

Beautiful Felicity is frustrated with her passionless marriage. Her inventor husband, Oswald, pays more attention to his mechanical devices than his wife's aching need. When she is rescued by the hot alpha fireman, Patrick, she doesn't even like his brash and crude manner, but she cannot resist the undeniable desire burning between them. Oswald is forced to watch the younger, well endowed fireman claim and satisfy his hot wife, and discovers how turned on he is by being a cuckold.
