No, save that for another day.

I reel in my desire and close her up. Sandra pants, asking me, "How...How does it look inside?"
"Very pink and healthy." I replied, while putting the tool away. "The last thing I'll do is check your anus."
She nodded and I rubbed her puckered hole in a circular motion. I then put in one finger making her moan. When I pushed it in farther she moaned louder.
I did two fingers...then three...then four...stretching her anus. "I'm prepping you for when I take your ass." I explain. "If I don't you'll be in pain."
"That feels so good, Doctor...please, keep going...I beg you!" She cried out. "Take me, now!"
"Not just yet. I've got to prepare myself too...and I need to inspect you too." I withdrew my fingers and picked up a different speculum, one that was used for examining the anus. I inserted it into her before opening her other hole. It was dark so I shined my flashlight into her and looked in...surprisingly it was clean.
Once I removed the speculum, I readied my member. "Now, let's do a deeper examination, shall we?"
Sandra nodded, and I entered her anus; slowly. Since I prepped her, she had no pain. I went deeper until my stem/hilt her ass. "You alright?" I ask.
"Y-Yeah."
"Time to go a little faster."
I began to move my hips, making her grab her breasts and play with them. She let out a squeal of pleasure when I hit her G-Spot.
"YES! YES! FASTER DOCTOR, FASTER!" She yelled at me. "TAKE ME FASTER! PLEASE!"
She wanted faster? Alright, I'll give her faster. I picked up speed, making her bounce slightly on the table.
In half an hour, we both cummed. But mine was larger. It gushed out again...flowing deep into her intestines. I pulled out of her and cleaned myself up. "You're fit and healthy, Sandra."
"Th-Thank you, Doctor."
I remove the white coat and placed it on the desk...signaling that we were done. I helped her off the table, and threw out the paper gown. "Go take a shower, honey. When that's done we'll order dinner. Oh and 'Razz-Berry Rain'."
She froze, and I whispered, "Now Sandra, when you come out of the shower you will put on only a large T-Shirt and walk around like that for the rest of the day. When I count to three, you'll do as I say, but not remember I told you to do this. 1...2...3!"
Her eyes cleared and she giggled, "I'll go get cleaned up, and I feel like pizza tonight."
"Very well."
She walks back up the stairs and I start cleaning the tools in ****. I had quite a few idea's how to spend the night....
