Never been pegged, but let me lay out my fantasy. She suggests it, I reluctantly agree. She takes it really slow and gentle to lull me into a false sense of security and then suggests we spice it up with some bondage. I agree and once I'm tied down she starts furiously jacking me off until I cum and then starts just going to town on my asshole now that I've got post-nut clarity and no longer want anything to do with this. Then the next night she asks if I want to try it again and "reluctantly" agree again.
