Been Thinking About My Old College Flirtations Lately

So yeah, been married for about 25 years now and still as horny as ever. Not that I'm complaining, love my old lady too much for that kind of shit. But lately, just keeps bringing me back to college days, those wild flirts in the library stacks or under some tree on campus. Got to be careful who you eye up when you're young and stupid like that, though. Anyway, open relationship now for a long time with my wife. Sometimes I feel bad about it, but then she reminds me we've always been honest since day one. Last night was an interesting one - this chick from work (she's in her thirties too) comes over and we just dive right into the heat of things. The way she wraps those long legs around my back... and yeah, I'll admit it, I'm a sucker for a woman's pussy lips when they're tight and swollen with arousal. We go hard, real fast - fingers sliding in and out so quickly that you can barely keep track of them. She likes to be teased, to have her clit flicked again and again until she's ready to explode. And I mean it was explosive too, I swear every time she comes there’s a new sound or movement from her body as waves hit her over and over again. Felt amazing to lose myself like that with someone other than my wife but not betraying the vows either. Guess at 45 you're still learning about your own desires and needs.
