If she's going to shake her ass at you, give it a smack.

You laugh and shake your head at your sister's dumb idea for a dare. She always seems willing to do something wild and carefree, and knows that you generally won't. You worry much more than she does about what people will think and how they will react if you just did any of the things that come to your mind. As a result, she teases you about it all the time and says you are repressed.

You figure it's better being repressed than looking goofy, like she does wiggling her butt at you. You decide to show her that she can't just offer a tempting target like that with no repercussions. So you reach out and give her ass a playful swat. "I don't need to see your butt first thing in the morning. Are you hoping I'll lose my appetite for breakfast, so you don't have to buy any for me?" You laugh.

It's not the first time you've slapped your sister's butt. You two have roughhoused since you were little kids. Her reaction is different this time though. She lets out a gasp, and jolts straight upright. Her face flushes red. "Dave" she breaths out, then almost pants a bit. "I wasn't expecting that."

"Well, let that be a lesson. Don't shove your ass at me, if you don't want it spanked." You say in mock seriousness. Then you notice the time. "We gotta get moving, or I'll be late for first period." You imitate Cartman from South Park, "Now go get dressed, so you can get me a sammich, girlie." You snort out a laugh.

You expect her to send an insult or at least a 'fuck you' back at you. You raise your hand to block the smack on the arm you think she'll try to give you, but that never comes. Instead she smiles and nods her head. "Yes sir." she says with a sarcastic tone, but you think you might sense a bit of admiration under it. Maybe she's proud of you for standing up to her and not taking her nonsense, but you doubt you'd ever get her to admit it out loud.

You grab your backpack as she's getting dressed. When she comes down the stairs, you see she's put on a short skirt, and a tight white tank top that hugs her breasts and shows off her toned belly. She was more covered up before she got dressed. "Reporting for chauffeur duty," she says with a grin. She slips her arm around yours, and leans into you as you walk to her car in the driveway. "Hmmm... you smell good today," she says turning her face towards your arm and inhaling. "New deodorant or body spray or something?"

You shrug. "I don't wear body spray. Same deodorant as always. Only thing I did different this morning is rush my shower. I probably smell less like soap, more like dirty me." You tell her as you open the passenger door and get it.

Abbie's eyes widen at that. As she slides into the driver's seat, she inhales deeply again. "Fuuuck. In that case you should try skipping showers once in a while. Girls might start asking you out." She chuckles. She starts the car and pulls out of the driveway. As she drives, her eyes glance over at you from time to time. When you look back at her, you can't help but notice her smooth, toned legs, and the outline of her nipples that stick up under the clinging fabric of her top. You pull your eyes off her, and face forward.

It's just a short trip to a drive through fast food place, where Abbie orders a couple of egg sandwiches and coffees. As she drives out, she says, "Seriously, is there a girl you really like? Maybe one you feel more comfortable around than others? If there is, you should try talking to her. It doesn't matter who she is, or if you think you can't get her. I think you'd make a great boyfriend. Any girl would be lucky to be with you." She sounds serious, not teasing you about girls like usual. Maybe she really wants to help you.
