Ron takes the offer

Ron stood there, contemplating his choices, the sounds around him, pure lust. Ron smirked, and answered Harry. “Give me the bloody potion. I’m going to knock this bitch up like never before.”

Harry smiled. “I’m glad you see it my way.” Harry snapped his fingers. A faint cowbell sound could be heard as Hermione sauntered over, rope in hand. At the end of the rope was Cho crawling in on all fours, but instead of being the slim, and sleek Cho that Ron had known, this one was chubby, but curvy in all the right places. Her dark chocolate colored nipples dragged on the floor, her tits, saggy, but plump. Ron could see that her rear end had exploded to gigantic proportions. Maybe if he asked nicely, Ron thought, Harry would let him plow that ass. Harry then nodded to Hermione who **** Cho up to her feet. Cho walked to Ron and presented one of her nipples to him.

Ron looked to Harry, confused. “What am I supposed to do with this?”

“This is a very special potion.” Harry answered. “It is administered from a human cow, created only to be bred and milked. Therefore, their milk in themselves makes a man virile, ideally to breed with the cattle, but it works for anyone. At least, that’s what Snape told me.”

Ron shrugged and started to suck on Cho’s leaking tit. “Mmmmm….mmmmmmooooooooo.” Cho whimpered, orgasming from the feeling of having her tits sucked. As Ron drank, his balls started to grow. Slowly they filled Ron’s trousers. As he was losing room, Ron removed his trousers and threw them to the side. Once they reached the size of coconuts, Ron released Cho’s tit, not wanting to be weighed down too much. “Mmmooo…” Cho thanked Ron, as she fell back on all fours.

Ron then moved to Lavender, who still was trying to reach climax. He removed both of her hands from her snatch and lifted her up, finding new found strength, he threw her on top of a table and started to stroke his cock, preparing to enter her pussy. “Oooohhhh…” Lavender groaned, as she tried to take her shirt off.

Ron acted fast and grabbed his wand. “Incarerous!” Ropes formed out of thin air and bound Lavender’s arms and legs to the table. “I’m going to pop your clothes off myself.” Ron snarled as he moved her panties to the side and lunged his cock into her wet opening. Lavender’s eyes went wide. They’ve had sex before, but she always took charge…she also faked all her orgasms with him. This time though, she could feel a real orgasm building, the loss of control, mentally and physically, turning her on even more. As Ron slammed harder and harder into Lavender, his enlarged ball sack reddening her ass with each thrust. Lavender started to shake as she orgasmed, her juices making Ron’s thrust even faster from the extra lubrication. “Ugh…here…it…comes…” Ron growled, quickening his pace. His ball sack slapped Lavender’s now glowing red ass once again as Ron released. Lavender felt as though Ron’s penis was like a faucet that had broken. The torrent of cum started to fill her up, her belly becoming a small dome that started to rise like dough. The buttons of her shirt started to strain, fighting the growing belly underneath. The bottom button was the first to pop, the next one followed. Pop, pop, pop, went her buttons, flying in different directions, as more and more of her belly felt the warm common room air. Soon, her belly towered over her, casting a large shadow over her face. Ron was not done yet as he placed a hand on top of her belly and pushed. Lavender gagged as she felt the pressure move above her belly and started in her breasts. More and more they grew, the sound of sloshing liquid growing louder with each second. She could feel her bra snap, now a ghost of this world. The buttons that were able to hold on gave up and once again the symphony of popping buttons filled the room as Lavender’s breasts grew to match her belly. Ron thrusted in once more, as he did, a louder ‘POP’ was heard, they both looked to see that Lavender’s belly button was the source of the sound, signaling that she was done. Ron finally pulled out , a small stream of cum flowing out of Lavender’s pussy.

Harry applauded Ron. “Thank you for testing that out. To be honest, I wasn’t sure what would happen. You could have turned into a girl for all I know.”

Ron chuckled, trying to catch his breath. “If you ever turn me into a girl,” Ron growled. “I would hope you’d still let me have a penis that came like this.” Ron and Harry laughed together, the moans and orgasmic screams music to their ears.
