Attack!

“Malfoy!” Dudley whispered as Malfoy looked up at her master. “How good is your magic? Could you incapacitate a group of people?”

“Mmm…for you master, anything.” Malfoy responded, grabbing her wand and pointing it at the door. Four girls walked in and turned the corner. Malfoy acted quickly, “Incarcerous! Silencio!” she casted as ropes flew out of her wand and tied the unlucky girls up. Dudley recognized them instantly as members of the swim team. She couldn’t remember their names at this time…their tight swimsuits causing her erection to grow harder than ever. “Drink this master…” Malfoy presented Dudley with a white potion.

“Uh…I don’t know about this.” Dudley responded, still skeptical of Malfoy.

“It’s okay,” Malfoy took a swig of the potion, “I promise it’s not poison.”

Dudley looked at Malfoy and then to the potion. What’s the harm? She took the bottle and drank some of it, then gave it back to Malfoy. Malfoy then gave it out to the other four newly made futas as Dudley, felt a pain in her groin. She looked to see a ball sack appear below her cock. She watched it start to grow, her new testicles growing from grapes to coconuts in a matter of seconds. “You…gave me back my balls?” Dudley questioned, feeling the heft of her returned ball sack.

Malfoy was coddling her returned balls. “These will only stay until we all cum…then they’ll shrink back down. Original master wanted to know something that I have to record after we fuck these girls.” She stroked her cock, getting ready to fuck one of the girls.

Dudley recognized the girl, it was his crush, Beth. Before Malfoy could stick her cock into Beth’s pussy, Dudley spoke up. “Wait, I want that pussy. You can fuck her ass.” Malfoy looked to Dudley, the sound of balls slapping growing louder as the other futas in the group started fucking the other girls, filling all their holes with cock, and obeyed. Dudley carefully guided her cock to Beth’s pussy, Malfoy’s engorged balls warmed her cock as she pushed in. Malfoy soon followed suit as she pushed her cock into Beth’s asshole. They were quick to find a rhythm. All the girls magically screamed silently. The two Asian twins were being fucked by Malcolm and Piers. One of them clearly enjoyed it more than the other.

“Unf, well Yumi, looks like Suki likes this a lot more than you do.” Piers commented, slamming her cock into Yumi again, watching Malcolm fuck Suki like a rag doll. Gordon and Dennis had agreed to share the redhead. Her slight curves giving them just enough incentive to spit roast her.

“Hey, Malfoy was it?” Gordon spoke, penis plowing away at Jen’s pussy glowing red from constant pounding of Gordon’s ball sack. “Got any potions to give these girls some assets? I know you said to make some other dick girls, but I wouldn’t mind at least one busty one.”

Malfoy stayed in rhythm with Dudley, fucking Beth’s ass with vigor, “In the bag, pink potion. Makes bimbos.” Malfoy struggled to get out as she came inside Beth’s ass. Beth’s eyes went wide as Malfoy unloaded her balls into her. She felt a strange sensation above her pussy as she looked down to see her clit starting to grow. The more cum that entered her ass, the more her clit grew until it was a seven inch penis as Malfoy finally stopped. Beth’s cock quivered as it came for the first time, covering the bench below her in cum. Dudley continued fucking Beth’s pussy, harder than ever after that display.

Gordon reached down into the bag and pulled the potion out. She handed it to Dennis, who then pulled her dick out of Jen’s mouth and **** her to drink the potion. Once she was sure that Jen had drank it, she put her cock back into Jen’s slick mouth. She could feel Jen’s lips expand into cock sucking pillows as she went back to fucking her mouth. Both Dennis and Gordon saw the potions effects in no time as Jen’s swimsuit started to strain and tear, trying to contain her firm and soon enormous tits and ass. A tear started to form, revealing her buttcrack as it grew and finally gave up as it exploded off of Jen. Her eyes went listless, having felt herself growing. She tried to move her arms to caress her now watermelon sized breasts and enormous bubble butt. That was all Dennis and Gordon needed to see as they came inside Jen, unloading everything into her poor body. Jen convulsed as her new dick grew rapidly. In a matter of seconds she had a new dick as thick as her arm.

Malcolm and Piers both finally came and unloaded into the two twins. Their bulges grew larger in their swim suits as their dicks grew to be long. The feeling of growing a dick tipped them over as they came inside their suits, cum spraying out any opening it could find.

Dudley had lasted longer than she expected. Still going strong, Beth’s newborn cock grew hard, even after the massive orgasm she had. Dudley decided to do her a favor as she approached climax and reached around and grabbed Beth’s dick and started stroking it. Since she was in control, it was easy to match her rhythm as Beth’s voice returned from the spell. She started to moan erotically, loving the feeling of having both of her genitals used at once. The aching heat from above her pussy from where Dudley’s enlarged ball sack had been slapping her for the last thirty minutes gave off an immense heat. Soon, Dudley slammed into her once more and came. Beth followed suit and soon covered Dudley’s hand in her cum. Dudley watched as Beth grew. Not her dick, but her tits and ass started to grow as her waist shrank. Watching her ass engulf her penis made her cum even more as she moved her hands to Beth’s growing tits. She fondled them as they grew, causing Beth to cum again and again. Once they were finally done, and Beth was the curviest futa bimbo anyone had seen, they both collapsed on each other.

Malfoy looked around the corner, and came back. “Master, more are coming, what should we do?”

Dudley looked around at all the futas stroking their dicks. Each one building up to yet another orgasm. “We’ve basically doubled our numbers here.” Dudley rose as she stroked her own cock back to attention. “I say fuck ‘em…literally.”
