Sexual desire is a very strange thing. Sure, boobs and boners and bums are par for the horny course, but sometimes we can't help but feel weirdly turned on by the most peculiar of things. Shouts out to the dude who got a hard on from using a hand-powered egg beater. Breakfast is served, b*tches.
Maybe you look over at your significant other and see that they're wearing the fuzziest and brightest socks imaginable. Now, fuzzy socks usually don't do it for you, but on this cozy occasion, you want nothing more than to whisk them off to bed and pound the sh*t out of them while those fuzzy socks caress your forehead. Hey, whatever floats your boat, bro.
Or perhaps you get dripping wet while programming away on the computer. You can't help it if the quick pulsing taps on the keyboard send jolts all the way down to your vajay! People like what they like, and sometimes you just have to masturbate to that piece of drywall above your bed that looks like a naked butt.
