the owner of Looters Rose, a succubus disguised as a tiefling, can feed just on sexual energy alone(if someone's turned on thats energy for her) her favorite is the fresh awkward energy of virgins but those arent as common as they used to be.
luckily shes found an untapped resource being TGed adventurers, so new to their altered bodies that they're practically virgins,
so she offers those *unfortunate* souls a way to earn money for a cure, a counter potion, etc though many of the *girls* that work for for her find that by the time they've saved enough they're happy with their new selves
