YRNKMTNDVAJ-331 - Caught my GF cheating with my best friend while hiding under the bed for a surprise

I'm a victim too, so what about it? It wasn't quite this close, but (｡-ω-) I kind of wanted to experience the intensity from under the bed. I moved up my return from a long business trip and raided her apartment! 'Huh... is that my girlfriend walking hand-in-hand with some stranger!(*_*)?' With a racing heart and anxiety, I headed to the balcony... 'Oh... they're just drinking. Of course they are.' 'Wait? W-well... kissing isn't cheating, is it...' In the dim light, their silhouettes appeared strangely vivid and obscene... Is that... a fellatio position? And cunnilingus with her legs spread wide like that!? She's squirting that much!? I see, a throbbing erection indeed... A 25-year-old's night, heading home with a bursting member.
