Isabel was a nineteen-year-old brunette with a sweet innocent face, a good girl. But looks could be deceiving and she was perhaps a bad girl which interested me. Isabel always seemed to wear the skimpiest of clothes when she came over to visit. This time she had on extremely short and ragged denim cutoffs and a yellow jersey that did little to hide the fact that she was not wearing a bra. She was my daughter’s best friend and was having a sleepover.  Also, she had a silver tongue stud.

"I have a question I've been meaning to ask you," I said to her the next evening on the way to take her home after her and my daughter’s sleepover.

"What's the idea of the tongue stud? What's the point of it?"

"Guys like it," Isabel replied.

"I've never seen a guy with one."

"Guys like it on girls."

"Why?"

"Guess."

I thought for a minute. I was afraid to say what I was thinking. "Does it have anything to do with sex?"

Isabel smiled. "You got it."

"Really? Oral sex?"

"That's it."

"Amazing. I would never have guessed."

Halfway to her house, we passed a deserted Walmart parking lot. "Why don't you pull in here for a few minutes," Isabel said.

"Why?"

"I'll tell you."

"Okay." I pulled into the parking lot.

"Park somewhere and shut the headlights off," she said.

"Would you like a demonstration?" she asked.

"Of what?"

"My tongue-stud."

"Doing what?"

"Guess."

"You're kidding me."

"You've been very nice to me and I would like to pay you back in some way.

"I don't know," I said.

"I'll tell you another secret about girls if you want," she said with a smile.

"What’s that?"

"A lot of girls shave."

"What do you mean—shave your legs?"

"You really aren't this naive, are you? I mean shave my pussy."

"Why?"

"Guys like it. Now can I demonstrate my tongue stud?"

I thought about it. "I know I should say no, but an offer like that is hard to refuse."

"And I would like to do it."

"Why?"

"Because I love older men, that’s why."

"What should I do?"

"You might want to unfasten your pants and push them and your shorts down to your knees. Even though I like to swallow, we don't want to leave a spot on your pants that might be hard for you to explain to your wife."

"Good idea." I unfastened my belt, unzipped my pants, and pushed them down to my knees, along with my shorts. Then I thought about it for a moment.

"As long as we're doing this, why don't we go for broke," I said. "I have a request to make."

"What's that?"

"I've never seen a shaved pussy before. Do you think you might be willing to take your shorts off as well?"

Isabel laughed. "Okay, I would love to." Isabel unfastened her cutoffs and pushed them down until they were on the floor. Then she did the same with her white bikini panties. She was as bare as a baby. She knelt up in front of me. "See?"

Even though the lights were off in the car, there was plenty of visibility from the Walmart parking lot lights. I stared at her beautiful hairless pussy.

"Can I touch it?" I asked.

"Sure you can Danny."

I did and it felt wonderful. I longed to put my finger inside her, but I thought that would be going too far.

"Just like you say, might as well go for broke," she said and she pulled the yellow jersey over her head. Now she was completely naked, with beautiful small breasts and hard pink nipples.

"Time to get to work." She stretched across the seat so her head was in my lap. Then she started licking my already hard cock.

"You have a very nice one," she said, holding it up and looking at it.

"How many have you seen?"

"Despite what you may think, not many. Just a few."

Then she started licking it in earnest until finally, she went all the way down to my pubic hairs on it. It took all of my will to keep from exploding into her mouth. She was right about the stud ring: That little silver knob made it feel even better.

Seeing her beautiful naked body stretched sideways out in the seat with her hairless cunt near my hand, I did what any sane man would have done: I started caressing her clit with my hand, then slipped my middle finger inside. She drew in her breath sharply. No wonder: She was all wet and slippery inside.

"Can I tell you something," I muttered.

She took my cock out of her mouth. She looked up at me with a smile.

"You were wondering if you could fuck me?"

"Could I?"

"Yes, I would love that." She got up on her knees, straddled my lap, leaned over to kiss me, then gently guided my cock into her wet slit and slowly went all the way down on it.

She waited a moment, then slowly started going up again. Once more I felt ready to explode.

"Christ, I hope a cop doesn't come patrolling through here," I said.

She opened her eyes. "No problem. I'll just tell them you're my daddy, and you're bouncing me on your lap."

I couldn't help but laugh. "I'm sure they'll believe that."

She leaned closer and whispered in my ear. "Do you want to come inside of me?"

"Yes."

"Then do so."

That did it. I came inside her in a shuddering climax and I think she came too. "That was wonderful," I said.

"I know. I thought so too. Let me clean you off." She eased herself off my still-swollen cock, laid face down on the seat, took my cock in her mouth, and licked it clean. I could not help it: I came again in her mouth.

"Hey!" she said.

"Sorry."

She licked it clean again. Then she sat up with a satisfied smile on her face. "Should I walk into my house like this, naked, or should I get dressed?"
