"I'm close to cumming!"

I hurriedly warned Crystal, afraid my imminent ejaculation might be here sooner than either of us wanted.

She released my cock from her mouth. It was slick with her saliva and a bit of her dark lipstick had rubbed off onto my shaft.

"We can finish this in a few," She said as she sat up. It was refreshing to get another view of the fullest pair of breasts I had ever seen up close. My hands shot up to her breasts and I groped hungrily at the soft flesh. She sat there, straddling me just below the cock, giving my erection a chance to cool off.

I had my fill of groping and focused my fingers on her nipples, each small, brown and perfectly positioned on the center, (or outward most part) of the vast expanse of her tits. She cooed softly as I pinched and twisted her nipples carefully with my fingers.

"You can be rougher than that," she invited. I flicked, bit and pinched her perfect nipples. Her cooing quickly transitioned to noises usually associated with sex, and she began to let out "oh"s and "yes"s in breathy gasps.

"I'm sorry," she said, "I've changed my mind about finishing your blowjob. Is that alright?"

"I'm a bit disappointed" I admitted.

"Disappointed?" She said, confused, "I think that's about to change"

Before I could stop her, or maybe because I was too charged with fiery sexual passion for Crystal's round, massive tits, she pulled my underwear and pants down towards my ankles and began stripping off the tights and thong she had been wearing. I watched, fascinated, as she stood and dropped her thong, revealing her pussy, its lips glistening with moisture. She straddled me once again and prepared to sit on my cock, still hard as rock as sticking straight up in the air like the fucking Washington Monument.
