Under the control of a real Mistress, your cock will learn to behave. You will know when is time to suffer and when it's time to cum, all of your pain and all of your pleasure belong to me and I will make you feel, exquisitely, every. Last. Detail.
If I was your therapist, I'd make you admit all your fetishes. Then we would figure out why you have them. The better understanding of your kink, the deeper into your fetish you can go, the sweeter the mind fuck domination.
