Fanny's First Tumble by Georgia Fox
Fanny Jones is a virginal housemaid, about to be presented as a birthday gift for his lordship's son and heir— a young man who must prove he knows what to do with a woman. The night, however, won't go quite to plan.
By dawn, Fanny certainly won't be a virgin any longer, but it's not the birthday boy who is responsible. Because when Dickon, the handsome groom of the estate, has to be called in to help out, he's more than willing to teach them both how it's done.
