Then I get an idea. I hold her up with the one arm, and with the other, I take my cock, and slide it up and down her ass crack, taking time to linger at her small puckered hole. I eventually stop there, and place the head of my dick so it is just resting at the entrance.
She starts to say something, until I quickly take my hand off my propped up cock and, leaving it pressing against her anus, move my fingers around to attend to her still throbbing clit, which has been grossly neglected over the last few minutes, all the while supporting her with my other arm. With this she lets out a long deep 'Ohhhhhh', and begins to sit down on my cock. At first it doesn't feel like I will be able to fit inside. I continue to fondle her clit, making sure that it pokes just in between the tips of my middle and ring fingers. She moans, and squirms from my touch, and it feels so good just having her sitting on me like that, with my cock just poking at the entrance.
It becomes obvious that pretty soon I am going to explode all over her hole before I have a chance to get inside. I mean, hey, I just had my first experience with condomless sex, and now, if I can only hold out, I'm about to have my first experience with anal sex. You'd be excited, too. I keep rubbing her, and she keeps squirming on me, and I can feel my orgasm building. I can't stop it. I'm not coming yet, but I know I will soon. And then, it happens. She relaxes and I slide in, all the way in. Oh, I can't even describe the sensation. Once inside her I begin furiously rubbing her clit, as I want her to get to climax with me.
