I was doing some work around the house one afternoon a year ago August when I heard a car pull up. It was not one I recognized right away, but then realized whose it was when I saw the young female driver get out. It was Isabel, Laurie's daughter, and Kim's granddaughter. I had been seeing the older two women, Kim on a regular basis (Kim Rediscovers Her Wild Side), and to a lesser extent, Laurie (Good Girl Laurie Goes Bad) for a couple of years. I had known Isabel for about eight years at this point. We were not especially close, though we got along well. I had helped her through some of her high school studies in the previous couple of years, since I had a flair for math, and was really good at geometry, a subject that was mystifying to her parents-and to her.
Her grandma suggested I help her with her third year math the year prior. Although it had been close to 40 years since I took it in school, some quick review brought me easily back up to speed. Isabel learned it well enough to get an A-minus, a grade that surprised her, since the subject had been particularly vexing. I had also aided in a couple of other projects along the way, mostly in the social studies realm. She was a good student and hard worker, so it was not a surprise to me that she did well. She was strictly off limits, of course, as she was 17; besides, it would have been creepy of me to hit on her anyway, seeing as I was already balling her mom and grandma. For her part, she behaved like a lady, and never did anything to lead me on.
The one thing that was distracting, however, was her tendency to wear thin slip dresses. They covered up-mostly-the parts that needed to be covered, but she'd shift around, and sometimes lean forward in front of me. She was a small girl, only about five feet tall, and maybe 100 pounds, with small, A cup tits. Like her forebears, she has thick, wavy, dark hair, in her case falling halfway down her back; like her mom, she has soft brown eyes. I thought of her more as a daughter than a bed prospect, and while the thought did occasionally cross my mind, it usually didn't last long. Still, when she'd lean over and I'd get a glimpse of her often braless breasts, my interest was piqued.
Now, a year later, Isabel was starting her senior year. Her family had moved around a lot when she was little and she changed schools often. When they got here, she had lost enough time that she was held back a year. I don't know if it made any difference; she was a crack student, always having an A average, or close to it, as long as I had known her. She had turned 18 in the spring, and would be 19 when she graduated.
I was sweeping off the pool deck when Isabel pulled in the driveway. I called out to her as she closed her car door. She looked my direction for a moment, then seeing me, smiled and waved. Sure enough, she was wearing one of those slip dresses. It was clingy, holding to her shape, and came midway down her thighs. As she approached, I realized she was probably braless as I watched her breasts bounce gently as she walked.
"Hi, Tom," she said when she came up on the deck, giving me a big hug. I held her close, holding her head to my chest, kissing the top of her head. We released from our hug.
"So what brings you over to see an old fat guy when you probably have better places to be??" I asked.
Isabel laughed. "I just got my class schedule for the year, and wanted to tell you I got in the AP class I wanted. All that work we did last year on those two projects paid off."
"Excellent!!" I said. "But, credit where credit is due, you put a lot of effort into those presentations. I just guided you along here and there."
"True, but your help really made a difference. I just wanted to stop by and say thanks." Isabel stood on her toes, took my hands in hers and kissed my cheek.
"So how is the rest of your schedule shaping up??" I asked.
"Pretty good. I got most of what I wanted."
"Cool. Can I take a look?? Let's go in and get a couple of drinks and we'll go over it." We went inside, and I got us a couple of Dr Peppers, and we sat on the living room sofa, Isabel to my right. She sat up close to me, pulled out her schedule, and we dug in. It was an ambitious program, with an AP English class as well as the AP American History. She was also taking advanced algebra and Spanish, among other things. "You've got a lot on your plate," I told her. "You sure you can make all that work, and work a job, too??"
"Well, I have a good mentor," said Isabel, smiling at me. "He helps me out quite a bit."
I laughed. "Yeah, thanks, but that's still a lot of homework. I took those AP classes when I was in high school a thousand years ago. It's a lot of reading, especially the English."
"I don't mind the reading. That's not too big a deal. Both of those classes are geared toward the AP test, so not a lot of homework otherwise. The math," Isabel looked at me, resting her head on my shoulder, "I have you to help me with." She looked up at me with her big brown eyes, smiling.
"I have a feeling you won't need much help once I get you where you understand it. It's not really that difficult. You're just dealing with various curves instead of straight lines. That class probably will have a lot of homework."
"Yeah, that might be time consuming. The other stuff, the Spanish and the physics, shouldn't be too much of a problem. I already know enough Spanish from living all the places we've been, and I'm pretty good with science. And I bet I can handle gym class," she said, again leaning on my shoulder.
"You don't mind helping me with the math??" Isabel asked again, looking up at me. "Last year I had such a hard time with geometry, and you really made it make sense."
"It's pretty logical once you take it apart. Just remember that one thing builds on another. Advanced algebra is a lot like algebra 1 and 2, just with curves. I'll help you through it."
"Thanks," said Isabel, looking up at me. My gaze met hers. She lifted her face about the same time mine leaned down, and our lips met. What I thought was going to be a nice, but short 'thank you' kiss turned into more than a minute of wrestling tongues. We broke apart, and looked at each other a moment in silence. Then Isabel reached up, taking my face in her hands, pulled me to hers, and kissed me, a lot more seriously this time. I felt her hand on my chest as we kissed, her gentle touch more electrifying that I expected, and I felt the usual response growing in my shorts.
I instinctively reached over, first holding her, then letting my hand slide forward til I was caressing her right breast. Isabel let out a sigh as I tweaked the nipple on her small tit, making it puff out. While I played, she reached down to rub my rapidly expanding cock through my shorts. She pulled my t shirt over my head, playing her hand in the hair on my chest. She let out a moan, then broke our kiss, putting her face in the thick hair.
