You caught your sister having sex. It has been on your mind for a while. You actually recorded some of it, holding onto it now so you could come up with something (anything!) to get her into trouble. But you couldn't think what exactly. The more you watched the video of her getting pounded by a guy from school, the more twisted your ideas got... but also, the more tight your pants got. You were finding yourself excited about it! Oh, geez! It's perfect though, your plan. Finally, you confront her. You say you've got this video and it's on multiple sources, so she can't just beat you up for it. Nope, she's totally backed into a corner... that is, unless she does what you say. A smile on your face, you now have the upper hand and the plan. You want your sister to have sex with you, too. She bursts into laughter and rolls her eyes, filled with irritation and anger in you. But you insist, this will not go well for her if she doesn't do as you say. Eventually, she caves. Her willingness to fuck you gets you so rock hard, you're ready for it! However, she isn't and says you both need to have something to relax. Something to just really make it happen and have her not feel... weird. Keeping the bottle to herself, she hands a shot glass to you that she poured in the kitchen. You sip it and cringe, but she insists you finish it as she chugs the rest of it. And as she finishes it all up on her end and you finish yours, you become... strange... feel... strange... everything is... weird... and... Now SHE is smiling. Now SHE has the upper hand. But what to do with it? She hates your guts, even more now that you tried to blackmail her. Big mistake. After much thought, she decides to EAT YOU UP. After all, there wouldn't be any evidence, right? Nobody would even THINK someone would have eaten you. No mess. No fuss. No nothing. And she'd have a full belly. It's a win:win for her. Oh, and as you come out her asshole and plop down into that toilet, she's going to look down at you... flush... and smile, as you go round... and round... and round...
