Fuck, so I think I managed to tick off three of my challenges at once... I'll admit that when I saw the post about these cards I thought it was a fun idea and all, but I was more just curious to see what those challenges would be, not sure if I'd actually go through with it. And as luck would have it, when I saw them and how a couple of them just seemed to fit together so well, it just set off my imagination and a plan already started to form that I wouldn't be able to stop.
'Fuck in a library'
'Fuck someone you feel is beneath you'
'Seduce and fuck a stranger in the middle of their normal work hours, at their place of employment'
just fit together perfectly and immediately made me think of the creepy old librarian guy at my uni. I have only interacted with him a handful of times, so I tried bringing up the twin thing but didn't really get any reaction. So I won't claim that I managed that.

He's way old, maybe already 60s and now for sure the oldest guy I've done stuff with. Kinda tall, maybe used to work out but is quite overweight now, balding with the weird circle of hairs thing, giant glasses, wrinkly and his cheeks kinda droop way off his face... Just way unattractive and one of the many standard creepy old guys out there, who I know are staring at me and stuff, but therefore I've already tuned out and don't even notice anymore. So when he popped into my head after reading my challenges, for a second it actually felt really revolting, but then it would just start to keep turning me on more and more over time. So last friday I finally caved and had to go for it, went to the library fairly late and found it super empty with him behind the counter. I didn't exactly have a plan, just wear something slutty, as in my shortest skirt, some knee highs cause it was kinda chilly, a thong but skipped the bra under a tight cute white top, lots of cleavage. Strike up a conversation and probably ask him for help with something. As soon as I entered the library and started walking over to him I could feel him eyeing me up, all the stuff I'm normally used to ignoring I now really noticed with him. It just made me hornier and hornier and I already felt a cold little wet spot in my panties by the time I started talking to him, nipples fully poking through my top, he definitely looked. I made up some stuff about needing a book, which I had already gotten a week earlier. But this way I could lean over the counter and show him on my phone, of course making sure my cleavage almost popped out and putting my hand straight on his arm. I also knew that book was from a section all the way in the back corner, so he tried directing me there after looking into the system. I straight up asked him if he could show me in person, if he wasn't too busy. He looked a bit confused at first, but a big smile and touching his arm more got him to agree. When I walked back there with him, I was already totally in slut mode, just tingly all over with excitement, but I knew I had to pace myself. It's not like in porn and you actually can scare guys away, althought I'm sure a lot of you guys wish it was :P

So I took it slow, made some small talk as we walked past a few people. Luckily back there it was completely empty as we looked for the book. I kept leanign in super close, he seemed nervous but got more used to it. Then he found it and of course I was super grateful when he handed it to me. I just stayed pretty close, kind of clinging to his arm, thanked him, put my hand on his chest and belly, moved it down more and more. He kept saying 'it's alright' and was quite polite. I stopped at his belt, had to move under his belly a little, and said something like 'but I would really like to thank you, can I?'. He asked 'really?', I said 'sure', took his hand and placed it on my breast, then dipped past the belt and felt for his crotch. From here on it all happened really quickly. He was definitely enjoying it, already rock hard. I knew there wasn't much time and I also didn't want him to finish before he could fuck me. I dropped to my knees, undid his belt and pulled down his pants and his dick kind of sprung free. Sadly nothing really impressive, but actually quite nicely groomed, looked funny how it just stood up under his belly. I sucked him for a bit and he got quite into it, grabbing my hair and stuff. I could also feel him get close pretty quick, so I stopped. I got up, smiled at him and took a couple steps to the end of the line of shelves, pulled him along behind me, pants around his ankles. At the wall there stood a few tables and I walked to the one right in the corned, no one was around. I hiked up my skirt, pulled my thong to the side and bent over. He didn't waste any time, as soon as I lay down his hands were on my ass, pushing me down quite hard and then he was inside me. I came almost instantly from that, but managed to stay pretty quiet. He just went for it though, probably not much more than ten hard thrusts and he started cumming inside me. He also wasn't quiet at all, so I'm very sure some people at the front must have heard. I wasn't going to stick around to find out, quickly got up, went past him with another smile and left the book on the floor. I quickly snuck to the other side of the library, then went to the exit from there so no one saw me coming from the direction of his grunting. Felt him drip out of me and past my leg on the way home. Now I just hope he's not working when I finally have to return the book I had already gotten.
