You know you can always go to your little sister about anything, so when you're feeling upset after yet another argument with your girlfriend, you head straight to your sister to tell her about it. She comforts you and expresses how much she dislikes your on again / off again girlfriend, insisting that she's nowhere near good enough for her big brother. Your sister pays you lots of compliments, telling you how handsome and amazing you are, and that you deserve to be with someone who will appreciate you properly! She asks if you and your girlfriend have split up again, and you admit you're not sure. It might just a be a little break, and then she'll call back later and want to make up.... Your sister is not impressed by this and tells you that you're stuck in a toxic cycle with this girl, and that this isn't how relationships should be! She wonders aloud how to try and break you out of this pattern, saying that it probably doesn't help that you're a horny young guy, and this girl is meeting your sexual needs. If only you could get those needs met somewhere else for a bit, just to clear your head.... Your sister then shyly, but excitedly, suggests that maybe SHE could help you out,... Purely as a favour, to help her big brother feel better, of course! You're unsure but she insists that she doesn't mind at all, and that she's sure it will help... You can even close your eyes and picture someone else, if it's too weird to think about your sister! You decide to give it a go, and agree to let your sister suck you off. You watch as she quickly gets carried away worshiping your cock; moaning as she sucks you and clearly getting turned on... Though it's so strange to see your sister like this, you find yourself enjoying it, and when she realises that her skirt has slipped up so you can see her ass and thong, you stop her from pulling it back down again; telling her you think it looks good! Your sister is thrilled that you're enjoying watching her, and enthusiastically sucks and licks your cock until you're ready to cum, telling you to cum in her mouth so she can taste you!
