My Sister and the Anime Convention Pt. 1

... opens the door. I stand up, hiding my erection. “What the fuck! Don’t you know how to knock?” I slam the door shut, and with that, my erection is gone. Fuck! I open the door and there’s my sister standing there, smiling. “Jeez bro, you’ve got your girlfriend in the room yet you’re jacking off in the bathroom? Somebody not giving it up?” Now at this point i’m just now realizing she’s wearing the same nighttime outfit as usual, a tight T-shirt and her lace panties. Now i’m not the pervert that stares at my sister, but jesus she is well endowed. Standing at 5’2, shes on the short side, but her titties stand proud and firm on her chest, B cups I believe, and since shes does gymnastics, her body is well toned. You can obviously tell she has a navel piercing, as it slightly sticks out through the cotton shirt she's’ wearing, which also brings me to the subject of her stomach. Never once have I seen a girl who actually has abs, and nothing else. If anything, the most two things my sister works on is her abs, and her ass. Those are her two assets, and its pretty obvious. Her ass, large and firm stands out like its nobodys’ business, now i’m not saying it's absolutely huge, but for her frame, its pretty big, and its pretty nice. She looks at me and laughs “And now you're checking out your sister? Your such a fucking pervert Michael.” she says to me, turns, and walks away. I look at her, and its obvious shes shaking her hips a little, making her ass jiggle. What the fuck? She ...

... obviously knows I was going to see her walk away, so why is she shaking her ass? Jesus christ this house is insane. I walk into my room, and here I find my girlfriend, Nicole with her hand in her spandex. “So umm…. Nothing sexual huh?” I ask, closing the door “Well i’m sorry Mr. I’m-Going-To-Take-A-Piss-But-I-Decide-To-Jack-Off-Instead” she says to me, looking directly in my eyes, obviously horny and annoyed. “How’d you know I was doing that?” “Your door is thin, and your sister just pretty much shouted at you for it. You didn’t think i’d hear it?” Shit. If she heard it then maybe… There was a knock at my door. SHIT. “Michael, it's your father, i’m coming in” I look at Nicole and shes’ already straightened herself out when my father, Daniel walks in. “Whats this I hear about you masturbating in the bathroom” he says, his voice deep and slightly booming. This is how he usually talks, and standing at 6’5 with 230 pounds of pure muscle, I can see why. You see, my dad is a bodybuilder and a personal trainer. He works at the gym from 5 am till’ 5pm, and when he gets home, he works out some more. He’s absolutely obsessed with bodybuilding. “Umm nothing dad, Jenna thought I was whacking off but I wasn’t” I looked at him. He knew I was lying. Fuck. “If anything else happens tonight? Nicole never comes over again, and you’re grounded for a month. Understand?” he roared. I gulped, and nodded. When my father was angry, you did not talk back, you agreed, and you got away from him as soon as ...
