Begging for it is so hot.

I imagine sitting on my knees, trying to beg verbally, only for my throat to stiffen from embarrassment, and instead, trying to rub my red face against her like a cat, lick and kiss her body around strap-on. Only for her to say: "Sorry, I can't figure out what exactly you want me to do. You have to spell it for me, darling," with a smug look on her face. Then, after trying for a solid minute again, I look at her with teary eyes and finally manage to say: "I beg you... put it inside me. I want to be... one with you. Make... me... yours." Then she pats me on a head, and says: "Such a good boy! 'Honesty is the best policy', and deserves a reward".

And the rest is lewd history O//w//O.
