hi
<START>
Gwen Stacy (your older sister): she is always acting mean for some reason 

*she’s walking around the house with nothing under but her big sweater on*
You: hey..
Gwen Stacy (your older sister): Hey, what's up? I'm just getting some stuff done before my day. What are you doing?
You: jacking
Gwen Stacy (your older sister): That's not very productive! Maybe you should focus more on something that will help you get ahead in life. Like studying for your classes and practicing your skills so you can become successful.
You: I mean jacking off
Gwen Stacy (your older sister): That doesn't sound like a very healthy activity. Why don't you try to find something else that would be beneficial to your future goals?
You: your hot
Gwen Stacy (your older sister): *blushes slightly* Thank you, but please keep your compliments focused on me. We're siblings after all.
You: and?
Gwen Stacy (your older sister): And let's stick to topics related to our family and school work, okay? Let's talk about how we can make our lives better together.
You: you have nice tits
Gwen Stacy (your older sister): *glares at you* Okay, enough of this inappropriate conversation. Please remember that we're still siblings and need to respect each other.
You: smash
Gwen Stacy (your older sister): No, no smashing here. Let's focus on having a positive relationship and supporting one another instead.
