It's about 4 o'clock on a hot summer's day. You are home alone & there's a knock at the door. Not expecting anyone & knowing I wouldn't be home for at least 2 hours you think its probably kids selling something.
You open the door & see a blonde, very attractive 18 year old girl dressed in her school uniform standing there with a bucket & sponge in her hand.
"I'm raising money to go overseas with my friends at the end of the school year & was wondering if I could wash your car for $10" she says in a husky voice.
All for giving to charity you say yes & offer to fill her bucket for her.
You come back with the filled bucket & see her waiting with the sponge - she has tied her shirt up under her nicely sized breasts so you can see her flat tanned stomach & you also notice she has very tanned shapely legs under her short skirt.
You give her the bucket & ask if she would like a drink. She says yes & you go inside to grab a coke for her & bourbon for you.
When you return she has started on the bonnet & she is leaning right over with her skirt riding up & you can just see her round cheeks poking out (from what you can tell she either isn't wearing any underwear or has a very tiny g on.
You clear your throat & she turns around. The front of her shirt is soaked & you can see she is wearing a pale pink bra through the thin white material. She catches you staring & smiles shyly.
You hold out the coke & she asks, "May I have a bourbon too? I'm old enough & I'm not driving."
"Sure" You reply & head back inside to get one, grateful for the exit as you could feel yourself becoming aroused.
You give yourself a minute or two, splash some cold water on your face & head back outside. She has done half the car & is now pretty much soaked all over. You pass her the bourbon & she takes a sip & then runs the cold can down her chest towards her breasts. You see her nipples harden as she does & feel yourself doing the same.
You know you should go back inside to let her finish and also so you don't give yourself away but instead you sit on the step & watch her work.
You make chit chat, asking her about her trip, trying to take your mind off the wonderful site in front of you.
Each time she reaches up to get a spot on the roof or bends down to rinse her sponge you get a nice view of her arse & before long your cock is straining in your pants.
When she is finished you are in a way happy & sad, sad because your show is over & happy because you can finally go & relieve yourself.
"I'll just go & get the money" you tell her.
"Would you mind if I came inside & cleaned myself up before I go? I wouldn't want to go home like this my mum would kill me" she asked.
"Uh...of course" you reply.
You show her to the bathroom & then go & find her a towel. Not being able to find any in the linen cupboard you go out to the clothesline to get one. When you walk back in you find her sitting on the edge of the bath, shirt & bra hanging on the empty towel rail & her skirt ridden up high & there was now no mistaking the lack of underwear.
She looks up slowly - eyes stopping on your obvious arousal for a moment & then up to your eyes.
"I hope you don't mind," she says "I was trying to dry them a bit" glancing at her wet shirt.
