The Only Difference is the 'S'

She seemed to sense that I was getting close, because her hand speeded up, pulling at my shaft, and her tongue started to swirl around my tip, turning that oversensitive part of me into a point of pure ecstasy, so good that it hurt. I felt the pressure build and the heat in my balls reach melting point, I was going to cum any minute and I so wanted Sam to swallow it.

"I'm going to cum." I warned her in a strained little voice, receiving a quick little squeeze on my shaft in acknowledgment.

"You don't have to take me in your mouth." I told her, hoping against hope that she would, but feeling the need to let her opt out.

She nodded slightly in answer and wanked my shaft even harder.

I tried to hold back to give her the chance to break free, but she didn't want to and I couldn't postpone for long, and so with a long warning groan I let go and shot my load into her mouth. She never hesitated, sucking and wanking hard on my shaft as if to milk every last drop from me, while I tried not to push up into her throat or to grab her head and ram it right down onto me. The sensations she generated were amazing, every spurt was met by her mouth descending onto me, every time my hips juddered from pure pleasure she ran her tongue around my cock to heighten it. It was the best blow job I had ever received, except for one thing.

The very minute I had finished ejaculating and she had swallowed everything I'd given, she pulled away, wiped her mouth on the back of her hand and scrambled out of the car without so much as a goodnight smile. It was as if the job was done, the bill was paid and that was that. Not the sort of thing to boost a man's ego.

It was a good fifteen minutes before I could drive away. Apart from the fact that my legs were like jelly, my chest was heaving and my heart was going like the favourite in the two-thirty, my mind couldn't take in her behaviour. First she did want to blow me, then she hesitated, then she did it and did it so well that she'd obviously had practise, and then she raced off as if regretting ever doing anything. I was confused to say the least.
