Partying With Your Hot Step-Sister

I open Step-Mom's cabinet and want to try with you, my step-brother, for the first time, but you're not so sure. I'm already going to get in a ton of trouble, though, so you'd better man up and do shots with me! Of course, I have no idea how much a shot is. Maybe I overdid it a little? Either way, when you suggest that we play with some sex dice that you have, and I'm just loose enough to go for it. They keep coming up with weird suggestions, though, like "Touch Neck." I think that we can do better than that. Say...fuck my tits?I mean, it hardly counts if we're step-brother and step-sister, right? We're just having fun--especially when you cum all over my big, soft breasts!
