MMMMMMMMMMMMM, I'm really likin' the floating feeling that I'm getting as I read this. Make no mistake, it's hot, like this part,
I use my hands to pull him wide and I look at him there. It hasn't been fifteen minutes since I finished fucking him and the skin is still red and inflamed. And wet from my tongue.
I wet him again, making my tongue flat and dragging it up from his balls to the top of his crack. And then I don't wait anymore. I push into him as hard and deep as I can. I curl my tongue and lick him on the inside and then pull back and watch his hole twitch and beg for more.
I lick a couple fingers and then press them to his hole, massaging it, but not pushing in.
and the ending.
I think it's pretty clever the way you're using the sex as a metaphor to establish the different points in their relationship. Nicely done. :D
