Harry turns up to serve Malfoy

Harry arrived at the prefects room and as if his presence was known, the door swung open and stood in front of him was a stunning Cho Chang, dressed in only a bikini. Harry's jaw dropped, Cho was stunning, she had big round firm tits pushing out, a fantastic body and there was little of her covered by the dark green flowery bikini, there was little to the imagination. Harry didn't say a word, just stared. "Hi Harry, come in" and Cho indicated for Harry to step in; as he did the room shocked him, it was like a beach party had been setup and several people were all around and some in the baths , everyone was dressed in beachwear.

"Potter! You made it." Malfoy shouted from the baths, waving Harry over. "Didn't you get the memo on the attire Potter? Nevermind, you can borrow a spare swimming set from the changing area, you'll see it.", Harry knew this was deliberate and this was undoubtedly a form of humiliation. Sure enough, as Harry wandered over he saw a pair of green Slytherin speedo trunks. Harry didn't need to check, he knew this was Malfoy intended. Slowly, Harry undressed, turned himself away from everyone and put on the Slytherin speedos. Harry hung around, folding up his clothes as the others partied, he could see Malfoy's usual crew, Cho and a few of her friends, there must have been about 15 people around enjoying a party. "Come on Potter, give us a show" Malfoy called, and Harry reluctantly walked over to the pool area as everyone took in a good look. Harry had a good body, thin but muscular and wasn't shy about it but nervous about what he was about to do. He couldn't help but glance over at Cho, who was now back in the pool with her friends and he was sure she was smiling at him.

"Right Potter, i think some time serving us will be a start", Malfoy smarted at Harrry, who looked at him annoyed.

"You didn't say anything about being your servant Malfoy, that wasn't the deal" and Malfoy coughed on his drink laughing

"Potter, this isn't a deal, this is you understanding your place. You'll do what I want, for as long as I want. Now, I think Cho could do with some drinks and snacks, why don't you sort that out" and Malfoy turned away and starting making out with Pansy. Harry looked over at Cho, she was giggling with her friends. Harry felt very exposed, the speedos were tight around him and with Cho looking hot, he could feel himself getting excited. Harry moved quickly to benches setup with food and drinks, he wanted to hide his growing erection and this gave him an out.

Taking as long as he could, Harry eventually brought drinks and snacks to Cho and her friends. As he put the drinks down, one of her friends reached out "I've always loved the Slytherin logo, the snake is just so...", her finger running over the logo, tracing along the snake and Harry immediately felt his cock responding, as she moved her hand to cup Harry, "...so... alluring, don't you think?" and she turned to Cho who was giggling more. Harry had to endure hours of servicing the groups needs, making sure everyone had a drink and food, everyone getting a stare at his almost nude body, and being an object for them to discuss, grab for fondle as they pleased. Pansy in particular had made references about size, whilst he was covered, it was obvious his package did not match Malfoy's and she was proud of her boyfriends prowess over the Gryffindor champ.

As the evening got late, Malfoy turned to Harry "Right Potter, now is the time for your demonstration..." and Harry's stomach dropped, "but, Cho seems to have taken a shine to you in your new role and I do like to give back to those who have been so generous, so i have an idea!", Harry felt a glimmer of hope but quickly reminded himself this was Malfoy, he was sure this would be worse.
