Banging attractive dark haired school girl

Im a 17yr old male in the middle of my A levels. one of my lessons consists of just me and an extremely attractive dark haired school girl who is 16. today i spent most of the lesson staring at her legs and feet as she slipped her feet in and out of her shoes, because i sit opposite her i have a perfect view up her skirt wen she crosses her legs. i glanced up at her face an noticed she was watchin me check her out, she then slowly opened her legs to reveal her sexy pink thong with a huge wet spot seeping through. my dick got instantly hard and i felt a small amount of precum slip out. she then slid her hand down beneath the desk and started rubbing her wet pussy sliding her panties to one side then pushing two fingers inside herself. i began rubbin my cock wishing i was fucking this girls tight cunt. after the class had finished she went to the bathroom and i followed i came up behind her and slid my hand under her ass an fingered her pussy it was tighter than i imagined. she pulled my cock out and began wanking me off. i pulled her into one of the cubicles and placed the tip off my dick in between her pussy lips and rubbed it up and down but not penetrating her. she got so horny and wet she slammed down on my cock and i was fully inside her she screamed wiv pain and pleasure as i rammed my dick in and out of her as fast as i could. it wasnt long before i felt her cunt tighten up her legs began to shake and she screamed as she orgasmed thick spurts of her cum shot out over my balls. i then shot my cum deep inside her little pussy as she begged me to do. after she gave me her thong and said next time she wants me to cum up her arse. im sniffing and licking her dirty cum soaked panties as i write.
