This is the conclusion of a story that started when I ran into a friend from ten years ago. If you haven't done so please go back and read the first three parts. I have more ideas and will continue to submit them as I get them typed.
Thanks to all who have provided feedback.

After a few minutes of rest, I was able to regain my breath and my strength. This little minx was definitely testing the limits of my body. While we held each other, we both purred as our bodies relaxed. Robin's arms were wrapped around my head as I continued to gently suck on her nipple. I felt her shiver when my softening cock slipped out of her hot tight ass.
Robin put both hands along side my head and pushed my face away from her chest. She looked me in the eyes and said, "I do hope you have one more left in you, I want to feel your hot sticky cum slide down my throat." I gulped loudly, smiled at her and then pressed my lips to hers. Once again, her tongue found mine as we continued to hold our bodies close.
Eventually, Robin broke off the kiss, pushed me back and then reached over to grab a towel. She pressed it against my chest and started to dry me off. I reached over and grabbed another, doing the same for her. We didn't have to get very dry, just enough so that we wouldn't leave a wet path through the house.
Robin took me by the hand and led me out of the bath, down the hall, down the stairs and into the back yard. The hot tub cover was off and she turned it on. The motor hummed to life as the tub was filled with bubbles. I held up my hand, offering it to her as assistance so that she could climb into the tub. Robin thanked me and took it, smiling as she lifted her leg and stepped over the side. With the grace of a ballerina, she continued to hold my hand and sunk into the warm frothy water. A soft groan escaped her breath as she let go of my hand and melted against the side of the tub.
My cock began to stir when I took in the site of Robin's beauty and grace as she lay there before me, naked. To think that we had already enjoyed several moments of erotic, sensual and intimate coupling, was absolutely beyond belief. Deep in the back of my mind, I wondered if this afternoon is the end of my fantasy with Robin or maybe the start of something good to come. Robin's purring pulled me from my trance, back to reality. Without hesitation, I quickly stepped into the tub.
My body began to relax as I slid further and further down into the hot water. I didn't realize how tired my muscles were until I was able to relax. I sat down across from Robin so that I could continue to look at her and wonder about what was to come. We just sat there listening to the bubbles for a few minutes when I felt Robins foot slip between my legs and slowly slide up to rest on my cock. I was still looking at her when she spoke up. Robin said, "I've really enjoyed my time with you this afternoon and I'm really going to enjoy sucking this cock again, in a few minutes. Only this time I'm finally going to get to taste that delicious cum as it shoots from your body into my mouth".
All I could say was, "Mmmmm. I can hardly wait". I pushed my hands below the surface of the water and started to massage her foot with both hands. At the same time, I slid my foot up between her smooth legs and gently pressed my toes up against her pussy. I felt her hand grab my foot and begin to massage it as she pushed my toes deeper into her slit. Her body was hotter than the hot tub.
After a minute, Robin quietly continued, "I just want you to know that I've never done anything like this before. I mean, I've never cheated on my husband. But last week when I saw you at the gas station, I told myself that I'd at least dangle the offer in front of you and if you called me, well then I'd move forward to see where this flirtation would take me. I'm really glad you called". Robin said all of this without ever looking up at me or even opening her eyes. She just lay back enjoying the hot water, the feel of my hands massaging her feet and the feel of my toes shoved deep into her body as her hand worked wonders on my own foot.
I carefully contemplated everything that she had just said. I didn't want to respond right away because I have learned that sometimes great sex can be ruined by too much pillow-talk. First someone says something then the other responds and in the process, someone misinterprets what the other is actually saying, completely ruining the mood. I didn't want that to happen here.
After a long pause, I responded saying, "To be honest, I wasn't completely sure if I was going to call you after we departed the gas station last week. I too have never cheated on my wife but I have had this serious crush on you since we first met over ten years ago. I've replayed our entire gas station conversation over and over in my head this past week. I finally decided that I would give you a call, if anything just to catch up with each other, in a setting that was a little more private than a gas station. I really wasn't sure what would happen this afternoon. I will say that I have had an excellent time today".
