You never really did understand why Heather, your current babysitter, hated you. Perhaps it was your family's wealth? Or maybe your own beauty that sent droves of boys at you. Then again. Despite being 3yrs. older and more endowed, she still couldn't compete with you. "It's her own fault for being such a bitch anyway" you thought. You were a gamer cheerleader, a strange blend but the people at your school (Minus Heather of course) didn't mind it. You have c-cup breasts, long glowing blond hair, twin mountains for a butt, and compared to Heather (Who had D cups, shoulder length raven hair, bubble butt, and generally snobby) you were a bubbly, cheerful, and overall happy person who was easy to get along with. However you're not as athletic compared to your friends and especially to Heather, and you were quite a klutz. She hated you for that, as you quickly stole her popularity away, leaving her a rather unknown person, at least compared to you.
You were bullied everyday by her, sometimes with wedgies, others with pantsing and the occasional spankings. Despite that you always tried to be her friend, and in a way you succeeded, as despite "hating: you, she quickly beat the hell out of a trio of new bullies once when they decided you were an easy target. So in a way she was your friend. Besides. You don't mind the wedgies too much, they felt nice, specially the way your soft panties rubbed your clit. And the humiliation felt nice too, as well as the spankings.
Which brings you to your current situation. A glowering Heather currently your baby sitter while your parents were off in vacation for 2 months or so. It's the start of Christmas break at least. Currently you are in nothing but your large pink bra, and a generic pair of gigantic granny panties, as those types of panties are the only ones you can wear that feel moderately normal and comfortable. Hence why your drawers are filled with nothing but large granny panties and bras. You were laying on your stomach on the sofa, waiting for Heather to start your wedgie session. "Usually she would've started by now. Wonder what's taking so long. Is she preparing a special wedgie for me?" Giggling quietly to yourself you waited.
Then you felt Heather's athletic fingers gripping your waistband, and suddenly you felt the panties invade your clit and ass as she pulled with all her might! Yanking you off the ground as Heather used her strength to being bouncing you, pleasuring you as you felt your large stretchy panties invade your anus. You especially loved the way she talked to you, and you could feel yourself getting wet, thankfully Heather was too distracted to notice your unfortunate "mess".
"Man. You must really love wedgies dontcha you nerd if you wear such big and stretchy panties. Good thing for you I'm going to give you a...
