First some quick background. I am my wife's second husband. Her first was the guy who fathered a baby with her in high school--a marriage doomed from the start as they say, which lasted about 3 years. He is way out of the picture now. We've been married 12 years and I adopted the baby, Marissa, who is now 19 and in college. I'm 36. We get along well, but the physical spark has faded a bit with busy careers and other things taking our attention.

A few weeks ago Marissa came home from college with some friends. My wife travels for her job and had to leave for the airport a few hours before they arrived. I would be playing bachelor all weekend, which was fine with me because I had a bunch of things I wanted to get done in the garage. One of my hobbies is restoring a 1986 Porsche 911. But that's a post for a different forum!

Marissa and her friends had plans to swim in the pool and then go out to meet some other friends somewhere later. I was in the garage when they arrived in three separate cars, one of which was a really nice little BMW 325i convertible. White, 1991 model, also known as an E30. I have owned a few E30 models. The owner was a very attractive 20-year old named Amber. Marissa introduced me to Amber and also Kayla and Maya, friends from her sorority. All cute, fit, and friendly. "Wow, would their male classmates like to be in our backyard in about 20 minutes," I thought, "what a show." I complimented Amber on her car while trying not to let my eyes linger too long on her long, tan legs, flat exposed belly or full breasts. She said it was a hand-me-down from her uncle. "It's okay I guess, but it dies a lot at stoplights." I also noticed a low tire and offered to take a look while she went swimming if she didn't mind. Of course she didn't (who passes up free mechanic work?), and handed me her keys before they all disappeared into the house to change into swimsuits.

After bringing the BMW into the shop and airing the tires, I went inside to grab my iPad to look up the idle setting and some other possible fixes for the problem. My timing was perfect, as four cute college girls were walking past in tiny bikinis over tan, athletic bodies on their way out to the pool. Marissa, Kayla, and Maya are blonde, while Amber is a brunette with reddish highlights. Picture a slightly taller version of the actress Eliza Dushku. Dark eyebrows, green eyes, total hottie. "Thank you so much for helping me with my car," she said with a big smile. "My pleasure," I answered. And it was also my pleasure to sneak a look at her sexy ass as she went outside.

Back in the garage I needed to look up a spec on the BMW and thought I'd see if she had an owner's manual. When I opened the glove box, there was a small stack of about 10 photos right on top. I couldn't help but notice the first one featured the lovely Amber, topless. Feeling a little guilty, I picked them up and looked at the next. Sprawled on a bed, naked, with a sheet just barely covering the best parts below her waist. Hair mussed, that big smile. Gorgeous. Well now I was two photos in so I looked at the rest. Don’t judge, you would have too! She was topless to near nude in every one, although her pussy was never shown. One had her pushing denim shorts low enough to reveal a tuft of dark hair, but that was all she revealed. They were still enough to arouse me.

After looking at the photos, I put everything back and finished adjusting the car's engine idle speed, which seemed to be the main problem. I also did a check of other basic maintenance items just for good measure and then spent some time on my old Porsche before going inside to have a beer. I decided to make virgin margaritas for my pretty little guests and soon they came in to sit at the bar while I played bartender. They were very chatty but I didn't mind the attention. Amber asked about her car and I said it was all fixed, but accidentally let it slip that I had looked at the manual. I could see on her face that I was busted. "So you found everything you needed in the glove box then?" with one eyebrow up, looking right at me. She didn't seem upset so I played along. I smiled and said, "Yes. Yes I did."

"Good to know," she said, and sipped her drink while still staring at me, a little smile. A little later while the others were still changing clothes, Amber cornered me. "So did you find anything besides the manual in my car?"

"My mama taught me to be honest," I said, "so I confess that I found some uhh, *extra* information in there."

"And did you look at everything closely?" she said, smiling, knowing she had me squirming and enjoying it.

"Amber," I replied, "any red-blooded man who answered no would be a liar, and I'm no liar."

"So did you like what you saw?" she asked.

Honesty being the best policy, I answered, "I most definitely did. You are absolutely gorgeous."

She blushed a little, to my surprise, and quickly explained that the photos were taken by her ex who she broke up with recently. They both took a photographic arts course and she confiscated the prints before leaving for summer break. "So," she asked, "which was your favorite?"

My turn to blush a little. "Well, uh, I'd have to say the one where you are crawling onto a bed, looking back at the camera with a devious expression while pulling your panties partway off. The look on your face is mesmerizing and even though it doesn't show everything, it makes a guy think about the *situation* happening."

In the photo, she had on some very loose fitting panties, the kind that don't seem to have a waistband, and the way she was pulling them off you could just see a little bit of lip in the shadows. The look on her face was a very appealing mix of come hither and playfulness--totally erotic.

"I like that one, too," she said. At that point we were interrupted as the other girls came out. They were all leaving to meet with some other friends. I walked them out and gave Amber a quick description of the things I had done on her BMW. She told the others she needed to stop off to visit her aunt and uncle before meeting up with them again. I told them goodbye and that I needed to go get cleaned up. I took one last peek at Amber's hot body when nobody was looking, and went inside for a quick shower.

Toweling off after my shower in the master bath, I heard a woman's voice call out, "do you always shower with your house unlocked?"

I wrapped the towel around my waist and stepped out of the bathroom. Amber was sitting on the end of the bed looking at me. "Don't tell me your car broke down!" I said, remembering my lack of real mechanic skills.

"Oh, no, it's just fine. In fact, that's why I'm here. I want to...thank you." She said, and her eyes slid down my chest and stopped at the slight bulge in the towel before doing a long, sexy blink and then looking back directly into my eyes. She has a thing about eye contact that really holds your gaze.

My pulse increased just a bit and I sat down on a chair in the corner of the room. "Is that so?" I said, crossing my arms "I should warn you that I'm a happily married man."

"I'm not here to steal you from your wife, I just thought it would be nice for you to see your favorite photo of me in real life."

And before I could protest (and maybe I didn't really try) she stripped off her top to reveal her practically perfect breasts. Her nipples were erect as she slid her hands over them, down to the top of her denim short. She hooked her thumbs into the waistband and pushed them way down, giving me more than a peek at her dark, trimmed pussy hair. "Oops, that's not the right photo," she said, and instead unbuttoned her shorts and wiggled out of them. She was wearing similar panties, but they fit more tightly than the ones from the photo, but I wasn’t complaining.

"That's OK," I said, "that was a nice one too."

She then turned and crawled up onto the bed, turned and looked at me with that same erotic expression and slowly started sliding her panties over the curve of her firm little ass. "Would you like to see what I did after the photo was taken?" she asked.

"I think I do, Amber." was my quick reply. And with that she continued pulling her panties off so that I got my first real look between her legs. As pussies go, hers was beautiful and obviously aroused, puffy, and pink. I could see that she was already a little bit wet. She rolled over and kicked her panties at me. Without saying a word, she let her knees fall away from each other and started rubbing herself while staring at me, but then stood up.

"How did you like the show?" she asked, standing there in front of me completely nude. Her pussy was trimmed to stay barely inside the edges of her little bikini bottoms. She had a little belly button piercing with a little emerald jewel that matched her eyes.

"Looks like it is still going on," I answered, my eyes caressing the curves of her body from where her hair fell across her collar bone, down the valley between her breasts, over her tight stomach, past the little sexy curve between her pussy and her inner thigh, down her well-toned legs to feet with unpainted nails. Wow. At this point my cock was well-aware of the possibilities and straining to make itself available under my towel. "Quite a thank you."

"You thought that was the thank you?" she asked. Next she came over to where I was sitting and straddled me. Her spread pussy resting against my towel covered cock, her breasts directly in front of my face, hands cradling my head. There was no hiding my erection. Giggling, she said "mmm, so you DID like the show!"

I could smell a citrus scented lotion and feel her warmth on me. I realized that I had put my hands on her hips. "Amber..." I said, "you are amazing, but...I'm not so sure this is a good idea."

"Part of you definitely thinks this is a good idea," she replied, "and all of me agrees. Listen, I really want to do this for you." I glanced down to where her pussy was straddling me and began wishing the towel wasn't there. She rocked back in response, letting me see how wet she was getting. I had started caressing her hips a little without realizing it. "You worked hard, so let me give you a massage, in a very specific place..."

She ran her fingers down my chest and abdomen, behind the towel to feel the base of my now fully hardened cock, with the fingers of her other hand circling her clit. I could feel everything easily through the towel. "We *really* need to get rid of this towel," she cooed, and started to stand.

But I held her firmly against me and looked into her eyes. "Amber, this has to be a one-time thing. I'm not looking for something on the side. Understand?"

"Sounds perfect, as long as you promise to believe me when I tell you this isn't something I normally do. Maybe it's the moon phase or the situation that has me wanting this so much," she said.

I let her go and she stood up, eyes locked with mine, and opened the towel. I was so hard that letting it loose was a big relief. Still looking at me, she moved forward and began sliding her wet pussy along the base of my cock, so that the tip was moving from her clit into her soft patch of hair, and back again. She was very wet, and soon I could feel her juices running down to my balls. After a few very slow strokes like this, she moved just a bit higher and positioned my cock head just at the entrance of her warm, wet pussy, watching my expression the whole time. Then her eyes nearly closed and she had a look of ecstatic anticipation. Suddenly, Amber leaned forward and kissed me very deeply, which sent an electric jolt up my spine and made my cock harder than I thought it could ever be. She lowered herself onto my shaft, pushing it in as far as it would go. She made a little whimper when she did that, still kissing me. Her pussy was soft, but tight around me. To say it was erotic is an understatement.

Pressing her pelvis hard against mine, she finally released the kiss. "Wow," she said, "I guess I decided to skip the foreplay." She was slurring her words very slightly, as if mildly drunk with the sudden release of endorphins into her bloodstream. I took her soft breasts into my hands and she braced her hands against my abdomen so she could move herself up and down. I let her warm up a little like this for a while until I felt like I was starting to get closer to cumming, then lifted her off and without a word pushed her back to the bed where she lay back and spread her legs. I crawled up into position above her and she started guiding my cock into her. But just then I moved downward, kissing first her neck, then her breasts, then down her stomach to her pussy. The mix of her citrus lotion with her own scent was intoxicating and she tasted amazing. I nearly pinched myself to make sure this wasn't a dream, that I was really screwing a gorgeous 20-year old. Using my fingers and tongue, I delicately and slowly brought her to a shuddering orgasm. I was glad the house was empty, because she wasn't quiet about it, moaning to a crescendo and finally shouting YES loud enough that I thought the neighbors might hear. I propped myself up so I could watch her beautiful breasts as she caught her breath. I moved the sheet partway over her to simulate another one of the photos from her glove box, but for the “real life” version she had beads of sweat on her skin. Much better.

It didn't take long before she pushed me down and took my still hard cock into her hand. She looked at it as if she had a fun new to play with, and I was happy to let her. She bent and took me quickly and deeply into her mouth, moving her tongue around my head while she bobbed up and down. Her blowjob skills were impressive. She gently caressed my balls with one hand while holding the base of my shaft with the other, working my head with her tongue and lips. It wasn't very long before I could feel a big release building. She sensed this and slowed down, moving off of my head and kissing my abdomen while her long brown hair teased my super sensitized cock.

"Back to the chair, mechanic," she ordered, pointing to the chair in the corner where she began her seduction, "I want to finish where we started."

I wasn't expecting her to take command like this. I went and sat down as requested, and she got on all fours on the floor, crawling toward me from the bed. She crawled right up, almost attacking me and quickly pushed my cock inside her wet, inviting pussy. This time while she fucked me, I rubbed her clit with my thumb. I could feel her starting to contract toward another orgasm, and at the same time I could feel my balls start to tighten as I got closer. If watching her soft pussy lips hold onto the shaft of my cock each time she rose up wasn't enough, observing the animal-like quality in the way that she was craving me pushed me to the edge. I could feel her beginning to tense and heard her whisper, "oh my god..."

I gripped her hips hard to control the rhythm and tensed every muscle in my body as I thrusted hard with each shot of cum into her pulsating vagina. She was cumming too, moaning with pleasure, and I felt five or six really strong, powerful contractions of my equipment. It had been a long, long time since I had come so hard.

She collapsed against me, both of us totally spent and drenched with sweat, breathing heavily. After a few minutes enjoying the feeling of our fading orgasms, I said, "If you're wondering, I feel very...appreciated now," I said. She just smiled at me.

We then showered together, during which she somehow managed to coax me to another orgasm with a fantastic handjob, and got dressed. We chatted a bit over some lemonade and ate some fruit before she got up to leave. As she drove away, I almost could not believe what had just happened.If you enjoyed this sex story, vote me up and I’ll share what happened the next time Amber came to visit.
