Tonight My slut was finally able to make good on her promise of giving me a blow job, and all I can say is, Damn!!!
This was by far her best effort ever. It seems to have really taken the pressure off of her that I will want her to swallow and she gave me her best effort. She sucked me longer than she ever has and stroked me with her hand while bobbing her mouth up and down on my cock. I made sure I was very vocal in my appreciation for her minstrations. It must have emcouraged her because even after her neck got tired, she continued to stroke me wonderfully and rub the underside of my cock across her wet mouth until I had the most intense orgasm I've had in quite a long time. My body completely locked up with muscle tension and I couldn't breath while I was cumming. I shot a huge load across her face and my belly, even shooting some into her hair.
When she asked me how it was, I told her it was Fan-fucking-tastic! She said that is what she was waiting to hear. Afterwards I complimented her on becoming quite the cock sucker, and thanked her for the great blowjob. She blushed and said thank you.
I think tonight might have been a turning point in the way she feels about sucking my cock. I hope so at least.
Unfortunately I couldn't return the favor, but I will definitely make it up to her when her period is over.
