Despite looking like a regular pegasus colt, Heart has a unique charm that makes fillies and mares desire him and his young body and normally, it's not even his fault. His mother was a succubus and because of that, it left some traits in his DNA that often causes fillies and mare to become infatuated with him before they want to take him off to a secluded spot for a little relief. Thankfully, Heart doesn't mind this and his Incubus DNA comes in handy to help satisfy their needs.
