[B4T] Training your perfect anal slut/slave

Hi there! I'm looking for a long-term slow burn RP where a top/dom trains a new bottom/sub to be his slave/slut with an emphasis and focus on anal kinks. I'm open to many dynamics for this story such as coach x player, professor x student, doctor x patient, and anything else you can think of. I'm cool with adding an age gap (18+ only) between our characters. I would be writing the bottom/sub in this scenario, and I'm looking for a top/dom writer. I don't prefer one-liners. Usually I like to write at least 2+ paragraphs for each post and looking for similar. I write in 3rd person and prefer the same. I use reference pics for characters, but I'm fine with descriptions as well. If this interests you, please send me a DM. My kinks are listed below, and anything bolded I would like included in the RP. Please come with your own list and anything you prefer to add into this story.

Bondage, D/s, CBT, Painal, Anal Training, Humiliation/Degradation, Oral (Both giving and receiving), Anal (Same as Oral), Non-con, Incest, Toys, Romance/Sensuality, Sexual Pain, Anthro/Furry characters, Knotting, Cum, Size difference, Power play, Physical conflict (resulting in the domination/control of the loser), Biting/Roughness/Hair pulling, Muscle/Body worship, Force/Coercion, Body Hair, Medical Play, Watersports, Piercings/Tattoos, Edging/Milking/Orgasm Denial, Chastity, fisting, and more, just ask.
