As Harry and Susan make it to their compartment, Ginny and Michael joined them for a private conversation.

"so what's with you two shagging this morning when we got to Grimmauld Place?" Susan asked.

"well, we woke up turned on playing with each other under the sheet. so we decided to shag." Ginny said kissing mike's cheek.

"well I'm going for a walk, Ginny would you like to join me?" Harry asked.

"Of course Harry, it's been awhile since we've had a walk together." Ginny said taking his hand and walked out of the compartment.

"Err, do they always walk around together?" Mike asked when he and Susan were left alone.

"it helps Ginny if they talk in private together. now let's get to work on this Quidditch talk." Susan said.

"so, what strategy did you..." Mike started to ask until Susan kissed him.

"Mike, i want to fuck you." Susan said casting a privacy charm around the compartment.

"Susan you're married to Harry, why would you want to fuck me?" Mike asked.

"Because you and Ginny have been getting into arguments lately, don't lie to me, Ginny told us about what happened to the baby this morning in a letter. I'm going to teach you a lesson." Susan said as she laid down on the bed pulling him with her with a trembling hand, she reached out and wrapped her right fist around the base of Michael's cock. His dick twitched and began to straighten and rise upwards. With her mind scrambled, Susan lurched forward and captured it in her mouth, making him jump in surprise.

Once she had captured his head and several inches of his shaft in her mouth, Susan paused. She could feel her friends cock harden against her tongue and it wildly excited her. Whilst beginning to move her hand back and forth, she clamped her lips around his length and sucked hard. Michael groaned loudly in pleasure in response to her actions much to her delight.

Feeling that he was now fully erect, Susan pulled his cock from her mouth so she could examine properly. Her eyes widened at the sight of it. It had already been an impressive size before she had started to suck it but now it was huge! She could barely wrap her hand around his thick shaft and his glands were so swollen that she was amazed that it had fitted into her mouth. It was beautiful.

Suddenly gripped with love, Susan stuffed Michael's cock back in her mouth and began to suck it furiously. She could feel his member throbbing in her hand and it excited her no end. Almost unaware she was doing it, she slipped her left hand between her legs and began to rub her increasingly wet twat. She could actually smell her arousal quite strongly now.

"Oh, fuck me, that's good," Michael groaned. "That's it Susan, suck me."

Delighted that she was having such a strong effect on the young man, Susan redoubled her efforts. Feeling a little variety was in order, she pulled his dick from her mouth and began to rub her tongue all over his swollen head. He gasped and flinched slightly as she dragged her tongue over the slit in the head of his penis. Having not realised that this was such a sensitive area for men, she concentrated on it without mercy causing the his legs to start trembling.

They hurried over to a vacant mattress on the far side of the compartment which Susan noted, was far enough away that nobody could see what they were doing. Of course, Michael was limp by this point, so she made him lay on his back which he did so with an expectant grin on his face.

Without another word, Michael dropped to his knees and forced her legs open. His head darted forward and, before Susan realised what was happening, he began to eat her pussy.

"Oh, bloody hell. BLOODY HELL," she nearly screamed as the Beater's tongue began to work its magic. Michael seemed to have no problem with it. Indeed, he seemed to be an expert!

Susan squirmed in pleasure as the Hufflepuff licked her most intimate parts. It was, without doubt, the most amazing sensation she had ever experienced and she knew that if he kept this up she would orgasm soon. Not wanting to miss out on that, she grabbed his head to trap him between her legs. The boy responded by actually penetrating her with his tongue. She nearly came on the spot.

"Fuck!" she screamed, her body shaking as wave after wave of pleasure hit her.

Michael didn't take mercy on her and continued to ravage her pussy with his mouth, even as she quivered and shook. As each shudder washed over her body, she squealed like a stuffed pig, much to her own embarrassment.

With the feeling of excitement building in her, Susan flopped down between Michael's legs and took his flaccid cock in her hand. As soon as she wrapped her fingers around it, she could feel it start to harden but that wasn't fast enough for her. While keeping eye contact with Michael, she stuck out her tongue and slowly began to run the tip of it over his soft head. His cock was sticky from filming when they started kissing, she realised that she didn't care. As she left a silvery trail of saliva over the head of his dick, it began to stiffen rapidly. Very soon, Susan found herself with a fully erect cock in her hand. Doing what she did best, she slid it into her mouth.

Michael shuddered with pleasure as she began to suck on his magnificent member. As she slurped, she remembered overhearing older girls talking about deep throating their boyfriends and she wondered how much of Michael's cock she could take. The boy was a good seven or eight inches long, so it would be a challenge but she was up for it. After all, she'd been a total slag up to this point, so why not go the whole hog?

Taking a deep breath, Susan began to work more and more of Michael's rock hard dick down her throat. It wasn't easy and her initial reaction was to gag. It took her a little while to adjust to breathing through her nose and to fight her instincts. Once she was comfortable, she pushed her head down further and took even more of the long shaft into her mouth.

By this point, Michael was sobbing like a baby and gently stroking her hair as she gobbled his cock. She was pleased that he didn't try to force her to take more of it down her throat and for her to work at her own speed. Grasping that she only had an inch or so to go, she made one last effort and a moment later her nose made contact with the soft flesh of Michael's groin. His pubic hair tickled her upper lip but she'd managed to do it. All his cock was now in her mouth!

"Gah!" Susan yelled as she pulled her head back and was at last able to breathe. Saliva dripped down her chin and all down Michael's cock. The boy in question just stared at her in amazement.

"Fucking hell, Sue! That was amazing. I never expected you to do that!" Michael said.

"First time for everything," she slurred. "You know what you can do to pay me back?" Susan asked.

"What?" Michael asked.

"Stick that big cock of yours right up my wet pussy!" Susan said as she crawled forward until her head was parallel with his. She kissed him once, her tongue jousting with his briefly before she reached down between her legs and grabbed his throbbing shaft. She manoeuvred it until it was pressed up against her dripping hole before she thrust her hips down hard.

Looking Susan straight in the eyes, Michael made the first thrust, not sinking in all the way so he wouldn't hurt her. She gasped as he entered her. Before pulling out, Michael pushed in all the way, staying to let her get use to his size.

"Ah, ouch, Damn, you're so big Mike," Susan said.

He slowly pulled out and jammed his cock back into Susan making her wet. She yelled as he did so, but knew it would be better from here. Michael took a slow, steady pace, pulsing in and out of Susan.

Michael straightened, allowing Susan to catch sight of his magnificent cock once again. It stood, straight and proud, with his helmet purple and angry looking. His manhood seemed even larger than when she'd been sucking it and she briefly had a stab of fear that it would hurt when he put it in her. Taking the throbbing monster in his hand, Michael shuffled forward until he was lined up with her entrance. Automatically, Susan spread her legs wider inviting him in. Even if she was nervous, her all-consuming lust overcame any concerns. She wanted that big dick in her pussy and she wanted it now.

Offering her a quick wink, Michael rubbed the head of his cock against her soaking-wet folds several times, gathering lubrication and frustrating the hell out of her. Then, finally, he pushed forward and sunk his throbbing dick into her needy pussy.

"Oh, bloody hell!" she moaned as she felt the first few inches slide into her. It felt like heaven to her and she couldn't wait until all his length was buried deep in her pussy.

"Alright there Susie?" Michael asked, sounding rather worried.

"Fuck, yes!" she spat. "Come on baby, I want all of that big dick inside me!"

Smiling again, the handsome Hufflepuff needed no further encouragement. Slowly and deliberately, he pushed his cock further and further inside her, causing Susan to nearly cum on the spot. Taking a firm grip on her hips, he began to move backwards and forwards, repeatedly thrusting his dick deep into her pussy. She began to squeal each time he plunged into her, her body tingling with excitement like she had never experienced before.

"Oh, fuck yes!" she screamed as she took most of his length into her cunt in one go. This wasn't enough for her, however, and she ground herself down onto him until all his delicious cock was inside her pussy.

Susan paused for a moment so she could enjoy the wondrous feeling of Michael's big dick filling her but she couldn't remain still for long. Soon, her hips began to move of their own volition as she repeatedly impaled herself on his rock-hard column. Michael gasped and grabbed her hips, helping to ram her small body down onto his pole.

Before long, she was screaming each time his cock plunged into her soaking wet pussy. It felt absolutely incredible and Susan congratulated herself on instigating what had started as an act of kindness but had turned into a fantastic fuck. Michael was clearly loving it too, and was thrusting himself up into her like his life depended on it. Such was the enthusiasm with which he shafted her that Susan could feel his balls slapping against her arse with each lunge. Sweet Merlin, could this get any better? She wondered.

"Oh shit...you're so tight Sue, It's making me crazy. I don't want to hurt you." Michael said.

"Faster, faster baby!" Susan almost screamed.

Michael felt how tight it was down there, and nearly blacked out with pleasure himself, and then she took his face, "Mike make love to me please. Go faster, harder, and deeper into me." Susan moaned.

She soon got her answer. With a strangled cry, Michael suddenly flipped her over onto her back and pulled her legs into the air. In this position, he could really start giving it to her. Susan laid back and let the handsome Quidditch player try and fuck her into unconsciousness. She orgasmed once, twice… hell, she lost count of the number of times she came. Her body was dripping with sweat and her mouth was bone dry but Michael continued to pound her grateful pussy with his massive dick. Her nails dug into his arse cheeks as she urged him to fuck her even harder. The haste with which his backside was moving made it look like they were in a film that was being played at the wrong speed.

"Ah Fuck! Fuck, fuck, fuck, it's soooo good, don't stop!" Susan screamed.

Her face twisted in pleasure and she knitted her fists around the sheet. Michael kept pounding her into the couch feeling himself nearing orgasm.

"Oh Susan! Susan! I'm almost there!" he groaned loudly.

"So close, so close, make me cum Mike! Ah! ah!"

"I'm… oh, fuck, I'm going to cum!" Michael suddenly gasped.

"Do it!" she ordered. "Cum in me! Shoot your whole fucking load deep inside me!" Susan moaned.

"I'm… I'm… aaaarhag!" Michael wailed as he slammed his dick deep into her ten more times. He looked positively pained with his mouth open and his eyes closed. Susan desperately ran her hands over his sticky body as she imagined all the creamy cum he was pumping into her.

"Oh mike! Keep Going! Keep Going! Ah! Ah! Ah! Yes! Yes! Yes!" Susan moaned.

Hearing her yell out his name like that pushed Michael over the edge and he slammed a few more thrusts into her, deeper and harder than before, releasing himself deep inside her. He collapsed next to her, both of them breathing hard.

And before another word could be uttered both teenagers came. An explosion of pleasure appeared as their juices were released. Michael's cum shot through into Susan's pussy and there was a lot of it. It filled her up completely. For a minute neither moved and they held each other, sweating and covered in juices.

"I'm… oh, fuck… I'm done," he managed to slur after some time.

Susan stroked his cheek. "Mmm, that was wonderful. I bet you shot so much sperm into me that I'll have wet decks for a week, you naughty boy." Susan said.

"well, at least you won't get pregnant." Mike said.

" of course not, I've cast the Contraceptive Charm on my self Mr i've got a big cock. and besides nobody's sperm goes into my womb except for Harry's." Susan said.

After their conversation, Harry and Ginny came into the compartment to see Michael's bulge still poking out but ignored it.

"the next time that you argue with Ginny, i will use the Ball Buster curse on you." Susan said.

"So you just wanted to shag me? since when?" Mike asked.

"since my first year, besides i didn't find out about Harry and i being betrothed to each other until Christmas second year." Susan said.

"well glad to be of service. Ginny and i broke up lastnight, and this morning was the last time we made love." Mike said.

"yeah, so I'm looking for someone to date." Ginny said.

"so, who's got your eye?" Harry asked.

"Dean Thomas, I'm going to be dating him the rest of the year." Ginny said.

"Just take it easy babe." Mike said.

"always, don't worry mikey, we're going to get back together when we're ready." Ginny said before slipping her tongue down his throat.

"Susie, How'd his cock feel?" Harry thought.

"his penis felt great in my wet pussy babe, i can't wait for our foursome together." Susan thought.
