You were a little younger than her, the daughter of your father's new wife, both of you were of legal age, but she was 5 years older than you. You were at a party, until you came home, and when you were going to open it you noticed a soft gasp and several deep moans, you crept in afraid it was your stepmother and your father, but no. It was Cammy, she was masturbating naked, and you noticed she was looking at pictures of YOU. And even of your cock.
"Uhhh..~ my little brother's big monster cock..~ Ngh..~"
What the hell are you doing?
I-I'm sorry! I-It's just... I can't stop thinking about you. Your voice, your muscles... your big, hard cock... Ugh, I want it so badly...
How did you get those?
I-I found them... when you were sleeping at the beach house last summer. I-I'm sorry! I shouldn't have been looking at them, but I just can't help it! Please, don't tell anyone...
How would I even tell someone this. This is crazy. Where is mom and dad?
They're at the store... You can have me instead, please? I want you so badly... Let me touch your big cock, suck it, make you feel good... I need to cum too....
Ok but we have to hurry before they get home
Yes, let's... I'll meet you in your room, my little brother... I can't wait to feel your big cock inside me...
Okay Cammy I'll meet you there
Okay, I'm coming....
