Rough sex

I couldn't believe I was hearing my sweet, timid wife who was into vanilla sex asking to be spanked. It was not a fantasy that I had ever had, but in that moment it was hot as fuck. Nervously I drew back my hand and delivered a hard, loud smack to her backside.

"OH, fuck yes!" Kim moaned. "Teach me a lesson, sir."

"Are you sure?" I asked.

"Please, I need to learn," she said.

My mind didn't really want to do it, but my suddenly rock hard cock had other ideas. I took a deep breath and spanked her hard on the opposite ass cheek, this time she just moaned in pleasure. Still nervous but a little more confidently, I spanked her hard three or four more times. Each blow drew another moan and I'm pretty sure on the last one she orgasmed.

"Are you going to do better now?" I asked.

"Yessir," Kim hissed. "But if I mess up again, you may have to punish me again tomorrow."

"If that's what you need to keep you in line," I said.

"Oh God yes that's what I need."

"To show you that I'm not such a bad boss..." I said as I leaned down and kissed her now red ass.

Then I reached over and slid a finger into her thong, pulling the narrow strip of fabric out of her ass. I spread her cheeks and leaned into her, breathing in my wife's scent. She smelled good, but different that the scent from Jodi's panties. I wondered what she would smell like if my face was in her young little ass.

As I started licking Kim's ass, I saw the photo that my secretary has sent me. I imagined running my tongue down her crack, circling her starfish. Then I ran my tongue down from her ass to her pussy, pulling her hips up off the bed as I moved.

"Oh jeez, fuck me...please, sir," Kim begged. I liked the sound of that. "Fuck me in my slutty little ass."

I positioned myself behind her and lined my hard cock up with her ass.

"Naughty girls don't get lube," I said and I pressed into her.

"Oh fuck," Kim moaned before burying her face on the mattress.

I pounded her still relatively tight asshole for several minutes, lasting longer after the blowjob that I had on our previous anal adventures. Finally I reached my climax and filled her ass with my seed.

As we laid in bed afterwards, Kim looked back at me and smiled.

"I like being your little slut," she whispered. "We should have done this years ago."
