As a Mistress, my duties are to dominate my subs, train them, and provide pleasure when they earn it.
I seduce her to try prostatic milking, and she loved it. I told her that it would be even better after some days in chastity, so she went for it.
One week later she was mad with lust… she wanted to be unlocked…
“I can’t do that, lovesome. Since you’re such a good girl, I’m supposed to give you as much pleasure as possible, and you drip more and moan louder each day,” I said.
“But Mistress, that’s logical… it’s a matter of physiology…” she replied.
“Logical, I know. Seems like we have an agreement then.” I answered before gagging her.
So… that’s her sissy story. That’s how I took her freedom and melted her mind…
If you want one sissy story of your own, just stay there until we’re done. And don’t touch that boner… Sissies don’t cum by their own hands…
