"Hey kids, Amelia's bogged down with political interference at the moment, so she asked if Susan could stay for a few days." James announced as he vanished the soot from the Floo off the two teenagers, both still in their school uniforms.
"That's fine with us, isn't it Susie?" Harry grinned, slinging an arm around the busty redhead's waist.
James raised an eyebrow as he noticed how Susan was dressed. Her white blouse was knotted tightly under her considerable cleavage, leaving her toned stomach bare, and her skirt short enough that it left an expense of creamy skin bare above the tops of her stockings.
"I hope I'll be getting good reports from Minerva for both of you." James noted wryly.
"No worries on that front." Harry gave the blushing redhead at his side a roguish grin. "And thanks to my slutty 'puff, neither of us will need sex ed lessons. Go on Susie, why don't you show Dad what you've learnt this year while I go and get cleaned up and changed."
With that he gave Susan a smack on her ass, sending her stumbling towards James, who caught her with both hands on her bare butt.
"Well, are you going to show me what you've learned?" James asked as Harry departed.
Susan gave him a nervous smile and sank to her knees in front of him. She made quick work of his jeans and underpants, leaving her with her hands full of half-hard cockmeat.
"Harry taught me to sloppily worship Potter cock like it deserves." Susan explained, beginning to trail kisses up James's rapidly-hardening shaft from balls to cockhead and back down, bringing her tongue into play with broad, wet slurps leaving trails of saliva and filling her mouth with the musky taste of his manhood.
She briefly indulged in sucking his fat cock, savouring the mouthful of juicy cockflesh before reluctantly pulling back and standing up. Looking about, Susan's eyes fell on a nearby chest of drawers, and hooking an arm under one of her thighs, lifted it up, resting her knee on top of the furniture and bending over, looking back at the man who had been her father figure for as long as she could remember.
James licked his lips as the nice little girl he'd known since childhood spread her legs like a cock-hungry slut, revealing a lack of any panties and a massive, clear buttplug spreading her poor sphincter wide.
"Harry taught me to take a good fucking in all my holes, but only he's allowed to take my plug out, so... will you fuck my little pussy Daddy?" Susan asked.
"Of course Sweetie. Here it comes, take my cock Baby Girl." James groaned from behind her, his cock hard and throbbing at her tight slit.
Susan gasped as her oversensitive cunt was speared full of cock, her holes double penetrated with his manhood and her buttplug. James filled her to the hilt with one relentless thrust, her tight walls grasping his shaft as the oversexed redhead shuddered through a climax simply from being fucked by her daddy.
There was no other word to describe it. She was being fucked. James pounded her pussy, his balls slapping against her clit every time he buried himself to the hilt in the hot, wet confines of Susan's eager quim. He could feel the plug Harry had seated in the busty redhead teen's ass as it jostled with each thrust.
"Yes Daddy, keep fucking your baby girl's pussy." Susan whimpered, throwing her head back.
"Daddy's going to fuck you sloppy and seed you, then Harry and I can share your cocksleeve holes sweetie." James assured the slutty schoolgirl, her tight cunt doing a superb job of driving him to his climax.
Seed her he did, her well-fucked cunt painted with a flood of cum as she drew out his orgasm, her folds leaking cum around his shaft as her overflowing twat and jizz-filled womb ran out of space for James to use as his cumdump, leaving the redhead a well-seeded bitch, dripping spunk down her thighs.
"Well, are you satisfied?" Harry called down from the top of the stairs. "Are we going to take her to bed and fuck her stupid, or has she not satisfied? If not then we can take her down to the basement for a good punishment."
"Can't I have both?" Susan asked.
