Sex first, then answer her

Since I'd already been warned that something was probably happening today by Janet's passionate kiss, I figured it wouldn't hurt to have sex first and then give Dr. Jones an answer. "It's one month since last time, isn't it? You're fertile again." I stood up, making Dr. Jones scoot back a bit. Then I unzipped my fly and pulled out my shaft. It all happened quickly, and the doctor gasped. I didn't even have to say anything else; she just leaned in, grasping my cock and sucking the head. I moaned as I cradled her head in my hands. When I had pulled it out, my cock was already starting to stiffen, but just a few seconds of Dr. Jones' talented tongue and lips had it fully extended. She bobbed in and out, taking more each time it went in her mouth.

"If we're going to be fucking every month, let's make it good." I held her hair in my hands and gently pulled her head toward me while I pushed out with my hips. I slowly fucked her mouth, pulling out until just the head was in her mouth, but never letting her take my cock out. I thrust a little bit farther into her each stroke, but never let her gag. Her mouth was a cunt and I was about to fill it. "The last time you sucked me, you caught my spunk in a bottle. This time, you're swallowing it."

Her tongue was a wonder on my cock; between it and the tight little noises Dr. Jones made in her throat, I was ready to unload down her throat. Sensing this, the good physician grabbed my ass and pulled my groin and pushed her mouth all the down my shaft. She started constricting her throat around my cock head, making me yell as I came.

"Fuck! Here it comes!" was all I could say as a flood of sperm flowed into her mouth. She swallowed repeatedly, getting every bit of it. It was heavenly.

She cleaned off my length, and then kept going, making me hard again. I moaned. Smacking her lips, she said, "Well, that won't get me pregnant, so let's get busy. You know the drill."
