That was incredibly hot to read. His cock is hard in his hand after reading it, even. Fuck. Rosy is so hot and he strokes his cock and thinks about the fantasy she's painted and thinks about how she clearly felt thinking about the fantasy (and the fact that she did it twice and it's s very good. Fuck. He strokes again, and his cock twitches, and he wishes Rosy was there to suck him off about it. Fuck.
But he should respond instead of touching himself so much. Even if doing that is very hot. He touches himself more and reads more of it. He likes her idea with the dress and the clothespins, he might like his idea better but she came up with one and he's not about to gainsay it. The rest... his concept of dropping a candy wrapper to make her pick it up has been expanded. Much expanded. The idea of someone, of Rosy specifically being perfect and graceful for him despite being filled and made to be horny, and even punished (wait, no, no antagonism)... er, doing all of that despite being horny, until it's too much, and then hurting her because he can, because he can and because she loves it. And then, presumably, fucking her, though the fantasy got cut off there because she came and tore her clothespins off and then did it a second time hurting herself with her fingers. John is rock hard in his hand. She's so fucking hot. He should probably stop touching himself to her hot and lovely letter, and instead write her back. (Possibly while touching himself some.) And then get off to it, maybe. Fuck.
Twice is fine, I'm glad you did. I like your fantasy. A lot. It's hot and wonderful and made me very, very turned on. I will probably go take care of that after this.
Want to do that with you, want to do that and watch you squirm and try to hold your poise and composure and when you almost can't put you in my lap and do whatever I want to you and hurt you as you thank me and then when I've had enough order you to your knees and have you suck me off. Would want to use other parts of you maybe but they're occupied.
Your writing is hot and good. Thank you. Good slave in waiting.
He dithers for a few moments about if it's too much or not, if he's being too brazen in writing things down, putting his fantasies on paper (or well, digital cyberspace whatever) but he's so hard and wants to get off to it. And so he sends it. And then heads to the bathroom to do just that.
