You're being such a good little sissy. I might just let you cum, but not yet.
Keep stroking. I want you to suffer for me. Look at my delicious body. My perfect tits, my tight little ass, and my cute frilly panties. I think yours are even cuter though. (giggling)
Edge for me. I want you so close that you could cum just from my breath blowing across the sensitive underside of your cock. But don't you dare cum. If you do, I'll tell my boyfriend about how I caught you in my panty drawer. Before you know it, the whole school will know you're a sissy panty slut! (laughing)
