You are just sitting in the kitchen eating breakfast when your sister emerges wearing a very short robe that is loosely tied. You cross your legs to hide your erection as she leans over to steal some of your food, letting her tits fall into view for a split second. She messes with her robe tie, giving you glimpses of her breasts, before the robe becomes so loose that you are just staring at her magnificent boobs right in front of your face. She asks you what you are staring at, and acts shocked when she realises you have been looking at her chest this whole time. Your sister loves to tease you, but enjoys making you feel like it's YOU who is the bad one who shouldn't be looking. She moves to the other side of the kitchen to make some coffee, giving you a smoking hot view of her from behind, as her ass practically is fully on show under her short robe. She leans across the counter, flaunting her pussy from behind, and the more she shifts her legs apart, the more open she becomes as she messes about making coffee. She then moves to sit across the table from you and picks up her phone to scroll through some messages. You can't stop staring at your sister as she opens and closes her legs, using her finger to trace a line from her thigh to her crotch... She sometimes catches your eye, but mostly just carries on looking at her phone screen, silently giving you permission to get hard over her. When she starts asking questions, you freeze up, not wanting to give too much away, but she knows... she knows how fucking bad you want her right now. What you wouldn't give to stick your cock in her and shoot your load inside... She agrees that you can look but not touch. Your sister will willingly show you her body whenever you want her to... but there are certain things that you must do for her, like pay her share of the rent and wash the dishes instead of her from now on. You agree to all of her terms straight away. When she asks you who has a prettier pussy, her or your girlfriend, you try not to answer, but in the end you tell her that she has the prettiest pussy in the whole entire world, and when you fuck your girlfriend, all you think about is your sister...
