Since I was relishing this opportunity to eat her pussy, I was doing what I could to draw out the pleasure she was feeling while I indulged myself. I wasn't trying to hold off her orgasm and not let her cum but was slowly building her toward what I hoped would be an even more intensely pleasurable orgasm than the first one. I could tell as her breathing rate continued to increase, her moaning got louder and longer and the subtle rocking of her hips became less subtle that she was getting close to cumming again so my focus gradually shifted to getting her to that next orgasm. I could feel her hot, wet pussy becoming even hotter and wetter and was getting even more eager to slip my throbbing cock into her but I was still enjoying the opportunity to eat her pussy so I still wasn't trying to rush things.
Right before she started cumming, she tensed up and went briefly silent then gasped as her body started shaking. I continued to lick and suck her clit while sliding my finger in and out of her still snug but now even more slippery pussy. Her orgasm was clearly long and apparently highly pleasurable, both of which had been my goals. When she finally appeared to have finished cumming, she remained where she was, staring out the window as she was recovering. I figured it was about time for me to experience some pleasure so I slipped my finger out of her and moved out from under her, standing then reaching around to unbutton her blouse. She allowed me to remove that then her bra so that she was completely naked. My cock was nearly bursting from my jeans by that point so I opened my jeans and pushed them and my underwear down far enough to free it. Gripping the base, I guided it to her pussy from behind then easily slipped into her despite how snug she was due to all of the natural lubrication. We both moaned as I pushed my full length into her while holding her hips.
As I slowly started to fuck her, the pleasure was incredibly intense and I was hoping to be able to enjoy it at least for a little while. As such, I maintained a slow, steady pace but was giving her the full length of my cock each time I slipped it into her. Once I had a good rhythm going, I slid my hands up from her hips to fondle her tits. I was looking beyond her at the view that was affecting her so but it wasn't really doing anything special for me; feeling her tits in my hands and her pussy gripping my cock was definitely much more of a turn-on. As we continued fucking, she was gradually pushing back harder as she picked up the pace. I was doing pretty good as far as hanging in there to enjoy the incredibly pleasurable experience of fucking her despite how incredible it did feel. I could definitely feel the stirring of an orgasm and, while I'd managed to last long enough that I wasn't going to feel like I came to quickly, I obviously would have much preferred to fuck her for a good deal longer.
Because she'd already cum twice, I was feeling comfortable with the fact that I expected to blow my load before I could get her to another orgasm. As such, I wasn't thinking about baseball or anything like that to hold out longer, instead just going with the rhythm and enjoying the building levels of pleasure. I could feel my orgasm drawing closer but, before I quite got there, Sara let out a cry and started shaking. She stopped pushing backwards as she was cumming so I just stood there with my cock embedded inside her, still fondling her titties. Needless to say, I was pretty surprised by her cumming again but, for her to cum three times, I was feeling like this might not end up being just a one-time thing. This orgasm appeared to be as long and intensely pleasurable as the previous two so I was happy to have been able to make her cum three times by three different methods.
When she had apparently finished cumming, she straightened up while moving slightly forward so that my cock slipped out of her. She turned to face me, looking flushed and a little dazed, and it took a moment before she could speak.
"Do you think it'd be possible," she asked, "to position ourselves so that I could suck your cock and look out the window at the same time?"
My first thought was that I could stand sideways to the window while she knelt but I wasn't sure how much she'd be able to see past me even like that. Fortunately, since we were in a small conference room, there was a small table available. I moved it over by the window and lay down so that she could lean over me and suck my cock while looking past me and out the window. She worked my jeans and underwear down a little farther but didn't removed them completely then gently gripped my cock and briefly pumped it. When she lowered her head and engulfed it in her mouth, I couldn't help but moan because it felt so good. My orgasm was immediately building up again as she slid her lips up and down my cock while gently pumping the base. She was staring out the window but somehow seemed focused on pleasuring me at the same time. I briefly glanced out the window myself but found it much more arousing to watch my cock disappearing repeatedly into her mouth. Since she was perpendicular to me, facing the window, I could also look to the side and see her naked body. I couldn't see her pussy or bush but I could see the curve of her ass and her tits in profile.
It didn't take very long with her skilled cocksucking before I was on the verge of cumming. My cock became even harder and thicker as my orgasm was imminent but she was completely unfazed, even as I started to spew with a soft moan. She swallowed my load while continuing to suck me off, stopping only when I was completely spent. As she let my cock fall from her mouth and straightened up, it was as though she came out of a daze.
"That was fun," she said with a smile as I was sitting up.
"That may be the understatement of the year," I replied, "That was amazing."
"Okay, you're right," she agreed, "Is your office usually pretty empty on the weekends?"
"Typically, yeah," I said, "but I bet I could find someplace with a window and a lock on the door that we could use during the week, too, if you're interested."
"I'm absolutely interested," she said, her eyes going wide, "as long as it doesn't end up getting you in any kind of trouble."
"It'd be worth it," I replied, "but I'll do some recon this week and keep you informed."
I was confident that there were unused areas of our office space that I could easily sneak her into and there was no way I wasn't going to take advantage of the effect of heights on her as long as she was totally into it, too. I figured if we kept her visits random rather than heading up there every weekend, there was less chance of getting caught. I also had her dress conservatively so that, if we encountered anyone, I could say that she was a student I was mentoring or a potential hire. Plus, fucking her after stripping off her conservative attire only heightened the level of pleasure.
