Jill and DJ, first spanking

I'd been dating a woman, Jill, about three weeks.
Jill was about seven years older than me, same height as me, and a bit heavier and broader than me.

After a  couple of weeks, our dates ended in the bedroom, hers or mine, in a rapid removal of clothes as we climbed onto the bed.

One such date started after I arrived at her place, in the bedroom ... not planned to go that way, but it happened quickly.
Afterwards ... I got up to pee, and as I was walking to the bathroom, she said, "Stop!"
I stopped and turned around.
She said, "No no, turn around again."
I did, and stood still.
"Wiggle your hips back and forth."
I did 

"I just love your ... ass."
"Thanks," I said, "May I continue?"
"Sure."
"Thanks again."
I peed, and started to return, when she said, "Turn around again..."
I did 

"Really gets me hot," she said.
"Hmmm... what do you like so much about my bottom?"
"Yours is ... really nice, but its male bottoms in general that I'm fond of."
"Really?  Wonder why that is..."
"Because ... I like to spank them."
My heart stopped.  Magic words.
"You ... like ... to spank 'em?"
"Uh huh," she said, grinning.
"How did that interest come to be?"
"With my first husband... who early on, expressed an interest in being spanked... so I did, and discovered, I really enjoy it. I gave him frequent spankings throughout our marriage."
"And um will that affect us?"
"I've been waiting for the right time to broach the subject, and now the subject has been broached. How do you fill about it?"
"I .. could .. maybe .. be into it?"
"Oh, would you care to try?"
I blushed, "Yeah, okay." 
She got out of bed, and sat on a chair next to the bed, and pulled me over her lap and 

I yelped and moaned at each hard slap of her hand to my bare bottom.
After fifteen minutes, she stopped and pushed me to my feet.
I stood, rubbing my bottom, and she said, "How was that?"
The swelling in my penis told the tale, and we got back into bed.
