It's Saturday night, and you're finally off work. You're a senior in high school, who plays tight end on the varsity football team. You're looking to relax and kick back, but, unfortunately, there aren't any parties tonight. Your best friend, Adam, has a killer video game collection and a huge house, so you decide to hit him up.

You get out your cell phone and call your best friend, Adam, who picks up on the first ring. You tell him you're bored, and he invites you to spend the night playing video games, eating pizza and doing what typical high schoolers do. Soon, you're at his front door, which is answered by his drop-dead gorgeous younger sister, Kara.

"Hi," She greets you, shyly, looking at you with her piercing blue eyes, twisting a finger through her long red hair.

She pulls her shoulders together, as though she wants to hide from you. The motion only causes her achingly huge, F-Cup perky tits to press together and double in size, before you; but you pretend to ignore it, easily - you're used to girls being awkward around you. She's clad in black little shorts and a tight white shirt top, for sleeping.

"Hey, Kara," Grinning, you walk into the house like you own the place, causing her to step back a little, intimidated.

She's a sophomore at your school, but she's tight and smaller (yet curvier) than most of the girls in her grade. She could easily pass as a sixth grader who developed early, but compared to her, you feel enormous, and your muscled arms look like they could crush her. With a cock your size inside her, she would be filled to the limit, with her moaning like a slut in heat.

You have to yourself to stop thinking sexually about her. Nothing could ever happen between the two of you, since your best friend, Adam, would kill you. With your popularity and your sexual reputation, you've never had any trouble finding chicks to fuck; but there's something about Kara that really turns you on.

"Is Adam upstairs?" You ask, moving past her.

She nods, and you smile at her again before joining your friend upstairs in the media room.

You and Adam play video games for a while before Kara comes upstairs and asks to join you guys, like she usually does.
