“Boys, I think it’s time we had a talk.” Arthur said when the family had gathered for the first time since Christmas. “I was going to let it go, but I’m afraid I can’t stop thinking about it, and I need you to be honest with me.” He wrung his hands awkwardly.
Charlie frowned. “What’s wrong dad? Has something happened to mum? To Bill or Percy?”
“No, nothing like that. It’s just, I couldn’t help but notice that the wards were showing signs of sex magic, and they were keyed to Charlie, Fred, and George. Have you had sex with anyone in this house?”
“With each other?” Charlie asked slowly.
Arthur shook his head. “No, no. Just, with anyone, while you’ve been here.”
Charlie shrugged. “We’ll, yeah. I didn’t know we couldn’t, and it also wasn’t something I wanted to announce to the rest, for everyone’s sake.” The twins nodded, agreeing with their older brother’s words.
“Well, if not with each other than who? No one else had been registered in the wards at the time, and the magic of whoever you slept with seems familiar to the wards.
The three shared a look. “Harry.” Fred admitted, shrugging. “Why does it matter?”
Arthur looked nervous all of a sudden, no longer just awkward. “Well, the wards are a bit old and really need a boost, and I saw that whoever you had had sex with had temporarily boosted them, but they need a full restart.” He admitted. “I’d hoped that with this person, since they have powerful magic, and I am the Head of the house, that we could fix them up.”
The three stared at their father. “And mum can’t help you, why?” Charlie asked.
Arthur winced. “She hasn’t got the same amount of power as, Harry, you said? Besides, when one of the pair is much younger, there’s the additional youth boost. Do you think he’d be willing?”
The three shared a look again. “Probably. Send him a letter.” Arthur nodded and then wandered off, to do so.

Harry blinked at the letter he had just read. When the owl had dropped it in front of him, he didn’t know what to expect, but a request to strengthen the Weasley wards with sex magic was not it.
Without hesitating, Harry responded with an affirmative, agreeing to meet the following weekend, in four days. He was always willing to help the family that had done so much for him, and was more than happy to help.
He was hard just thinking about it.

Having done some quick research of sex rituals, Harry had a vague idea of what he would be required to do; and so under his outer robe, he wore nothing but a see through cover, rather like how Mrs Malfoy had worn, actually.
He’d greeted Arthur, shoved the nerves and awkwardness as far down as he could, and focused on the fact he would have to do nothing in this but feel, and let his magic just respond.
Arthur had led him to a circle made from a pattern of roses, candles, precious stones, and runes. It was in the centre of the ward dome, meaning it happened to be in front of the house, in the middle of the front lawn.
Removing the outer robe, Harry shivered in the cool air, feeing the sun warm his skin. He lay down on the grass in the centre of the circle, pulling his legs up and spreading them.
Arthur approached the circle, equally naked though foregoing the transparent robe. Waving his wand and chanting in Latin, he entered the circle, untying Harry’s robe as he did so and letting it fall to the sides, exposing as much of Harry’s flesh to the sky as he could.
Still chanting, Arthur ran his hands sensually up the teen’s legs, feeling the smooth, soft skin and tracing rune-patterns into the muscle.
Harry shuddered, already feeling his magic react, and his breath hitched as Arthur trailed fingers over his cock, swiping the gathered drop of pre-cum and spreading it on Harry’s chest.
He continued up Harry’s body, drawing out aroused gasps and moans from the teen.
The cool air prickled his skin, hot hands kneading his muscles, and grass ticking his sides. The sky was beautiful as the sun set, and Harry’s blood rushed with the exposure he felt, fucking out in the open.
Warm oil was spread over his skin, making it shine and relax. A good drizzle was squeezed onto his hard cock, the liquid running down his shaft, and between his spread arse cheeks, the shaven skin providing no hinderance to its path.
A finger traced patterns down his chest and finished at his entrance, pressing firmly inside. Arthur fucked the finger slowly, soon adding a second and third.
Harry panted, the sensuality flustering him in a way rough sex usually didn’t, and his body felt treasured even as the fingers were quickly withdrawn and replace with the blunt tip of a cock.
Harry groaned softly as Arthur pressed into him, his magic rolling under his skin and crackling in the air, having been teased out by the deft fingers.
Harry clutched Arthur’s arms as the father of his best friend and fuck-buddies slowly pulled back and then pressed in, beginning a slow and steady pace.
Harry was panting, pushing himself back into the erection as much as he could. It wasn’t long before he felt his climax approach, and Arthur wrapped tight fingers around his base.
The teen whined but let Arthur go, and was rewarded with some rapid chanting and the removal of the fingers. He came with a soft cry, Arthur immediately scooping the creamy liquid and using it to draw runes into Harry’s chest and arms.
He kept the infuriatingly slow pace for what felt like an hour (it was fifteen minutes) and damn if Harry wasn’t impressed by his stamina and focus. No wonder the man had seven kids.
Suddenly without warning, Arthur rammed him and Harry screamed, his relaxed and on-edge body thrashed at the rapid onslaught of thrusts into his delicately teased prostate.
Harry’s magic reacted wildly, pulsating around them in time with Arthur’s thrusts into the tight little arse.
The air was filled with soft gasps and panting breaths, the grass rustling under them. The air was charging with magic and it made their skin prickle.
Arthur kept pounding him sharply, contrastingly gentle hands still massaging the cum into his chest, and Harry lifted a weak hand to his cock and slicked it with the oil, easily running his hand over the shaft and clasping it in his hands.
He jerked himself off, hand alternating the timing with the cock in his arse and his body pressing into it.
Harry gasped as Arthur flooded him, and kept fucking him even as Harry came a second time. Arthur merely wiped up the fresh cum and began rubbing it into his own chest as he kept pumping the fertile seed into its depository.
Even as it finished Arthur kept going, softened cock hardening inside of his weakly twitching hole, and Harry shuddered at the battering of his sensitive prostate.
Harry released a cry as Arthur suddenly pulled out without warning and flipped him onto his hands and knees, rutting his cock to Harry’s arse until it was taken in again, quickly and eagerly.
They fucked doggy style, Harry’s face pressed into the dirt, drying cum gathering it and melting his magic into the earth itself.
One of Arthur’s hands snaked around his waist and clamped around his trembling cock, pumping it in time to his somehow quickening fucks until he released one last chant and thrust so hard into Harry it pushed the teen over the edge for the third time.
He then abruptly pulled out, cock spraying magical seed into the air around them. Harry’s magic caught it before it could fall and pushing it into the glowing air around them; the wards.
Landing in the pile of cum covered dirt, Harry’s body shuddered, his magic feeling like it was just fucked by Arthur’s like their bodies had just fucked.
Harry let the cum deposited inside of him dribble onto the dirt below him, and he remained still until Arthur’s last spurt of cum splashed onto his back.
He lay there gasping, body weakly shuddering, as Arthur staggered into him, cock finding its new home easily, back inside the warm sleeve as the cold air cooled their hot bodies.
Arthur rocked them gently as the sex magic dissipated, and his body shuddered at the power emanating from his Family wards.
“Oh Harry, you are beautiful.” He whispered to the teen. “So powerful, and absolutely gorgeous. No wonder so many can’t bleep their hands off of you.” Even as he said this, calloused hands ran around Harry’s shivering body, easily warming it back up.
Harry huffed a laugh but didn’t protest the exploratory touches as he relaxed into the warm body, his own satisfied, and his magic tingling.
