"How d'you expect me to pierce this slut's tits if they're bouncing everywhere?" Tonks exclaimed, stepping back again from the chair where her future boss was sat on the lap of her cousin, his cock sheathed in Amelia Bones' tight cunt, double penetrating her with a fat buttplug.
She was supposed to have a half-day at her part-time job at the piercing parlour, the job that paid for her Auror Academy studies. However, thanks to her cousin Harry arriving with the head of the DMLE in tow, she was running late. Apparently it was her boss's birthday present to Harry, getting to fuck her as she got her tits pierced for him.
"I can't help it." Harry's hand smacked down on Amelia's ass with a loud crack. "She's so worked up that every time you get near her she's cumming 'round my cock and the buttplug stretching her arse."
"You need to discipline your sluts cuz." Tonks shrugged indifferently, then conjured some thin velvet ropes which she tossed to Harry.
In moments, Amelia found herself, her holes filled with as much cock and buttplug as she could take, being tied up. First her arms were crossed behind her back and tied together, a last loop across the binding to tighten it enough to force her to arch her back, presenting her fantastic tits to the room. Then he tied fresh bindings around the lower part of her wrists, and, with a hand in her hair pulling her back, he lashed the rope from each wrist to the opposite ankle.
Harry finished binding her with a bright red ballgag. Another smack across the redhead's thick ass elicited a yelp of pain, arousal and surprise which allowed him to press the gag into Amelia's mouth. He tightened it at her nape, and spanked her again, this time only getting a muffled whine.
"Now she can't move, we just need to stop her cumming without fucking herself on your dick." Tonks grinned.
"Orgasm denial?" Harry asked, fondling Amelia's ass, her sphincter distending around the fat buttplug each time he pulled it halfway out of her gaping asshole.
"Nope." the Pinkette picked up her wand, a spell-lit beam reaching out for Amelia's belly. "There. Guarenteed fertility spell. Now if she squeezes that fat cock of yours too much she'll be getting an unexpected birthday present from the birthday boy."
Amelia went very still, but while she froze externally, Harry could feel the walls of her tight pussy flexing around his cock, and he was forced to stop her instinctively trying to impale herself deeper on the cuntful of cock she was taking.
At last, Tonks was able to finish the job, Amelia's svelte form trembling as first one, then the both of her erect nipples were pierced through. The metamorph gave Harry a grin and he immediately resumed fucking the redhead, his cock pounding into her cunt with wet slaps. He'd already decided that Amelia's generosity had to be repaid.
Tonks flicked her wand and the ornaments Harry had chosen, a pair of nice fat rings to adorn a pair of nice fat tits floated over. They broke open and flattened out, hovering at each piercing. She carefully pushed them through, stretching the piercings. Then they curled around, reforming as rings and closed once more. Permanently.
The redhead's freshly-pierced tits heaved as she was fucked hard from underneath, the thick, throbbing cock thrusting into her fertile cunt a wonderful counterpoint to the fat plug that left her anally filled. Tonks had one more wicked surprise for her, a fine chain, in the same rose-gold as her nipple rings, chosen to match her auburn hair.
Amelia could only whimper, whine and moan through her gag as Tonks clipped the chain on to her nipple rings, Harry tugging on it and spanking her ass as he fucked her over the edge of a messy mutual climax.
Amelia could feel her womb flood with just a single burst of thick, hot jizz. Harry's hips jerked, slamming against her thighs as he drove his cock balls-deep into her needy quim, each thrust another jet of his fertile seed continuing to drown her cunt. She knew that this was her destiny, being fucked and bred like a bitch after freely making herself Harry's fucktoy.
