Andrew doesn't quite finish

The stroking was soft; his dick feeling as though it was gliding in and out quite slowly. It was almost painfully slow. It felt amazing, but Andrew wished that his friend would just pick up the pace a little. It was simultaneously exhilarating and frustrating. He had just taken Katie's virginity -- well, she took her own virginity with his cock. At the same time, she was being far too gentle.

The 'thrusting' stopped suddenly as Andrew felt Katie readjusting her grip on the base of his rod. He felt the movement continue, but at a slightly different angle. It was still slow, but slightly faster. At least she was picking up the pace a bit. Her slick pussy felt amazing as his dick slid out and nestled deeper again. This pace kept up for a few more minutes.

Eventually the movement became slightly faster. Finally, she was going a good pace. Katie fucked herself this way for about half a minute, and Andrew finally felt his balls beginning to churn. He was going to be able to cum and this would all be over. As he was getting close, he felt his dick shoved deep into Katie's wet hole and she stopped. Then Andrew felt her pulse around his cock. It felt wonderful. So wonderful that he felt himself getting closer still.

He was just a few seconds from spewing his cum all inside of his friend, when he suddenly feels his cock pulled free from the velvet vice. He felt his dick twitching, readying its load, but all it felt was the cool air. He felt his rock hard dick placed gently down on a surface. No way, was she done? But he was so close!

Andrew reached desperately down to his crotch, attempting to pleasure himself in any way possible, but no matter where he rubbed or poked, he got no closer to cumming. He tried this for a full minute before giving up. He was so turned on he could think of nothing else besides having his orgasm.
