I've been dreaming of this moment for a long time. Me and my girlfriend have been talking about it for a while now, and finally, it's here. I've invited my best friend over to our place, and my girlfriend is out running some errands. This is the perfect opportunity to get up close and personal with my stepsister. She's always been a bit of a mystery to me, and I can't help but be drawn to her. I find myself constantly wanting to touch her, to feel her soft skin against mine. As I'm talking to my friend, I can't resist the urge to grope her a little bit. She doesn't seem to mind, and even seems to enjoy it. It's a strange feeling, being caught by my girlfriend while I'm getting intimate with her sister. But at the same time, it's exciting. It's like I'm living out my fantasies as a cuckold, and it's all happening in real time.
