Jim, the old man across the road.

"He's my choice" giggled Daisy.
"That old bloke? Why him?" asked her bemused older sister.
"He always stares at me when i'm outside but whenever i look at him he turns away or walks inside or something". She turned and quickly walked out the door up to the gardening Jim.
"Hello there, do you want to come in my house for a little bit?"
The old man looked up at the scantily dressed beauty and immediately and noticeably changed his demeanour.
"Oh... Hello young lady, What...Why do you want me to come in?"
"Just come inside please...." her tone changed at the please slightly to a more overbearing tone, further unsettling the old man.
Grabbing his hand before waiting for a response she pleasantly pulled him into the house with almost a literal skip in her step; after the shock of this sudden event Jim merely made a barely audible "Okay..." as he trailed in behind his object of desire.
As she dragged him into the house, the surprised neighbour dutifully followed only to stop on seeing the young girls mother kneeling almost naked on the floor and the rest of the barely dressed crew.
"What's going o-"
"Sit down here" Daisy interrupted gesturing to the sofa, followed by a perfectly accepting response from the new guest.
"John, put on some music. Something sexy." Whilst doing as she said John couldn't help but feel a slight pulse in his cock considering the commanding tone coming from his innocent and gorgeous looking young sister.
As the music started playing, the now crowd-like group watching the age spanning pair watched as Daisy whispered in the stunned old man's ear before begginning to gyrate her hips and sway to the music. She continued to move and the two older woman were the first to notice the slight bulge in the old man's trousers, showing everyone else as they quietly watched the show.
Daisy was now giving small responses to the old man's roaming eyes whilst caressing herself mid dance. "You've always wanted my big tits haven't you, to lick the nipple, put your old cock between them- they're far too young for you." she almost berated whilst swueezing her now erect nipples.
"I bet all you want is to put your cock in my soft little mouth?" sucking on fingers metaphorically, "or my tight little pussy? You old pervert trying to get inside such a young girl", she began rubbing her thong panties and pulling at them to outline her tight pussy.
By now Jim's arousal was strikingly apparant with everyone else in the room fixated on when he'll blow. "Poor old man, mustn't get much action" Mrs Johnson whispered to the suddenly less tired Tracy.
"Or-" Daisy paused making intense eye contact with the now sweating and fidgeting old man; "You're a really dirty old man and want to get inside my poor young ass!" stressing the final word as sheturned and wriggled her hips, the buxom teen began to bend over and leaned back resting the soft pearly skin of her bottom onto the grey trousers of the old man's lap.
The instant of contact the effect was evident, the rest of the room listened to the groan and moan of old Jim and then saw a dark spot appear turning the grey trousers black before Daisy finished the job and rubbed her ass all over the elderly neighbour's caged, flowing penis.
In the calm that followed, Daisy stood up quickly and then commanded "OUT! Get out now, you've cum in your pants you old perve, now get out!". Rising off the sofa with a mix of shock, embarrasment and yet slight satisfaction on his face Jim revealed the dark patch across his trousers before scurrying out of the house.
"You naughty old man!" Daisy shouted after him before slamming the door in faux anger. As she turned her back to the door and leant against it, a wide smile spread across her pretty face.
"That was so hot!" the young girl exclaimed, "He even got some spunk on my ass! It must've seeped through!" turning to show the small amount of white goo on her left cheek before wiping it off and licking it saucily- noticing this the two young men in the room began to stir with excitement once more.
"You liked that then?" her mother asked.
"God yes, that was amazing, it felt so good to do that to him" she beamed before looking up to the ceiling and shutting her eyes.
"Yes, we thought you had, see, old Jim wasn't the only one to make a stain" Mrs Johnson giggled to everyone else before Daisy glanced down and noticed a small damp patch on her panties.
Her initial embarrasment of her obvious arousal faded within seconds before she smiled to everyone and gave her pussy a small rub and sat down.
"Well, i think Daisy passed that one with flying colours, what now?" Her older sister mused.
