My most common fantasy lately is that I'll be making out with some girl (coworker, friend, or just somebody I see wherever). She'll start stroking my penis and nibbling on my ear til I get really hard, then she'll whisper, "I love your cock! Can I cut it off?" Not sure why that makes me so horny, but it really does.

What would you say to her?

In the real world, I'd never let it happen, but my fantasies always end with her chopping it off. I'd simply tell her, "It's yours. Please cut it off!" The details vary from one time to the next, but it usually involves her sucking my cock until its incredibly hard. Sometimes she'll pull a knife from her purse and do the deed just as I'm cumming. Other times, I imagine she'd pull me to the kitchen by my erection, make me stand at the counter, place my cock on a cutting board, stroke me for a bit, then THWACK!
