You figured it must have been a joke at first. After your encounter and little bargain with the incubus in the House of Hope, allowing him to shift into your form for his purposes you hadn't thought much of him. You felt in every few weeks. A little surge of pleasure whenever he made love in your shape but he never contacted you. That was until you got a letter from him thanking you for your form and passing on some casual reviews of your body from his clients. So you wrote him back and to your surprise you now had an infernal penpal. You exchanged more and more letters and truly got to know each other and to your surprise...he seemed to genuinely like you.
