With Monday, the couple's life returned to normal. Dan left for university in the morning, Sophie had her online classes and Jimmy headed off to his classes also.

The nerd had erections several times during the day that he had trouble hiding and Sophie's mind wandered frequently in the day. Many times she thought about how daring she had been and how easily she could have caught for it, but truth be told she had really enjoyed what had happened the night before. Her pussy was wet non stop and she found it hard to concentrate on her classes.

Jimmy got home early afternoon and she heard him go straight to his room, she suspected why. She wanted to relieve herself also and thought about going into the next room for a mutual masturbation but didn't dare risk letting things get out of hand. So she decided to take control of things on her own when the bell rang.

She curiously went to answer the door but when she got there, Kristy was waiting for her at the entrance. In her hand was a shopping bag.

"What are you doing here? I wasn't expecting you. Come on in. Actually, I'm surprised you even rang." Sophie said with a smile.

"After the last time, I didn't dare take any risks. I'd rather wisely warn that I'm coming." She replied with a laugh. "Are you alone?"

"No. Jimmy's home in his room."

"Then come. Let's go to your room."

Sophie looked questioningly at her friend but followed without a word.

"Okay. I have a present for you."

"But it's not my birthday. Why...?" She couldn't finish the sentence, her words trailing off as Kristy pulled a huge life-like dildo out of the bag she was carrying.

"I originally wanted a black one because they looked amazing, and they were a similar size as Jimmy. But I saw this one and decided on this one."

The fake dick was indeed similar in size, and according to the box, it gives a very realistic feel for a better experience.

"Are you saying I should fuck myself with this thing!? That's huge."

"Exactly. I know you dream a lot about your 'little' roommate, but at the same time, you want to be faithful to Dan. That way you can at least imagine that... you know. Who knows, Dan might even like it if you use this. It's like a three-way, but still just the two of you."

"Are you crazy? I'm definitely not showing him that. He'll think I want to fuck Jimmy."

"Well. You know that. But I bought one for myself too. And... it was an unforgettable experience." She winked at her friend, and after a quick goodbye, left the shocked Sophie alone with her new and giant dildo.

She glanced at the clock.

'After all, why not? Dan won't be home for a while, and that's what I wanted to do... this is just a little aid to help me. Which isn't that small after all.'

Then she opened the package with trembling hands. When she first touched it, she found that it did indeed have the touch of real skin. Like she was really grabbing Jimmy's cock. Only it wasn't as hard, but that didn't change the experience. It really felt real. Sophie had just realised there was a suction cup on the end. So she could use it comfortably in the shower too.

'It's like being in a porn movie.'

flashed through her mind.

Sophie made sure the door was locked once more--she didn't want prying eyes on her this time--and then stripped naked and settled herself comfortably on the bed. She'd never used a dildo before, so she didn't know how to begin.

'A little wetness will be needed.'

Then she licked her finger and started rubbing herself. True, her pussy was already wet, but she liked the touch. Then, closing her eyes, she slowly took the 12-inch dildo into her mouth. She began to suck it passionately, and her crotch tingled at the thought of having such a big cock in her mouth for the first time. Even if it wasn't real. It was a real art to take in as much as she could, but slowly she adapted to the new size and stuffed more and more into her mouth. When she couldn't take any more, she checked, but more than half was still out. But with a more decisive movement and a release of the neck muscles, she slid as much as she could down her throat. Immediately she started to gag and had to take it out to keep from vomiting. It was a strange feeling, but she was also proud of herself. Judging by the drool trail on the dick, she could swallow two-thirds of it. More than that, would have been almost impossible.

She then continued a little more gently. When she thought that if she drowned or fainted here, she would be found with a huge dildo in her throat. It made her smile a little, but she risked nothing. She kept sucking passionately on the cock and fantasised about Jimmy in her mouth. When she felt her huge toy wet enough, she thought the time had come. She gripped the cock with both hands and fitted the tip to her opening. She took a deep breath and pushed the first few inches in. Closing her eyes, she moaned and slowly pushed more and more in.

When she felt she had reached her own limits, she looked down and was amazed to see that a few more inches were still needed to take it all in.

'Oh my God. I wouldn't be able to take Jimmy all the way in.'

She fantasised. Sophie was getting more and more into the fantasy and the feeling. She was enjoying the way the Jimmy-looking dildo was getting deeper and deeper inside her, and she was giving herself over completely to the sensation. She wished she could have tried the new toy in the shower but didn't dare sneak out. Nor did she want to break the moment. She could feel her orgasm coming on, but she wanted to try other positions. She glanced around the room, and her eyes caught the mirror.

Without a word, she reached over and applied the suction cup to the mirror. She almost laughed at the sight. It was as if the mirror had grown a horse's dick that would fuck her in no time. She didn't wait long, turning her back and letting it slide in from behind. She let out a loud moan, which Jimmy heard in the next room. The nerd started to pay more and more attention and it was obvious to him what Sophie was doing and he started to stroke his cock again. His ear was plastered to the wall to hear her moans as much as possible.

Sophie's body tingled as she moved faster and faster on the wet cock and with a couple of strokes, in this position it sometimes slid deeper than she was used to which was a little unpleasant but she was getting used to it. In a sudden moment, her round ass was pushed almost all the way up against the mirror, causing almost all of the cock to penetrate her. She screamed out loud and stayed like that for a few moments. Slowly she resumed the movements and now she could take in almost the entire length of the dildo. She felt herself getting close but didn't want to cum yet. She slowed her pace and let go of the cock, panting. Dripping with her juices, it was still dangling on the mirror and with a popping sound she pulled it off.

She had to change position and wanted to drag it out as long as she could. She sat back on the bed and placed the dildo under herself. She held it with one hand and slowly lowered herself onto it. She moaned loudly and sat down to ride it.

"Aahh! Jimmy! Yes! You have such a huge cock!" She didn't even realize she'd said it out loud. She was just playing with the nerd in her imagination, but she said her thoughts out loud. This in turn caused him to hear everything crystal clear in the next room and his cock to get even harder. He was aware that she was masturbating and fantasizing about him but he didn't know that she had a dildo as big as his dick in her hole. Sophie's lustful moans were getting louder and Jimmy was jerking his meat faster. The girl in the other room was now leaning both hands on the bed and riding the cock like a cowgirl. She was very wet and aroused but still couldn't take it all in.

Sophie rode the dildo under her more and more violently and felt the end was near. On the other side of the wall, Jimmy was also masturbating fiercely and when she moaned a loud one, he was cumming a huge one and spray out all of his load. He wanted to wait more but couldn't hold back. As Sophie moaned his name he couldn't resist. His cock didn't soften though and as long as she kept going, Jimmy didn't stop jerking his still hard cock.

Sophie was very close but she wanted to pull as long as possible so she slowed down. In the throes of pleasure, she didn't notice Dan had arrived home, so when her boyfriend entered the room, the blood was frozen in her veins. She still had just enough presence of mind to wrap the blanket around her waist so Dan couldn't see what was between his beloved girlfriend's legs. But that also meant Sophie had to act like she was just sitting on the bed so Dan wouldn't suspect anything.

But Sophie was able to do this only by lowering her ass, which allowed the thick cock to penetrate deep inside her. It took great effort not to moan as she felt the tip of the dildo poking her cervix.

"What's the matter, honey. You're so weird." Dan asked suspiciously, looking at his girlfriend's contorted face, but then his eyes locked on her bare breasts. "I see you've been waiting for me. I'll be right back, I promise. I'll just take a quick shower."

"That'll be... very... nice. I miss you already." Sophie stammered as she felt the dildo deep inside her. Her pussy was tingling, and this little interlude didn't help that she could cum at any moment. She felt her whole body begin to tremble within seconds as the onset of orgasm took hold of her. The heavy seconds seemed unbelievably slow as Dan undressed and left the room in his towel. Sophie watched him almost breathlessly, and when all she could see was his back, her body began to shudder wildly. When the door closed, only then did she dare to rise, slowly pulling the prick out of her wet cunt but still stimulating points that the shaking refused to stop. She could surrender to the orgasm and only hoped Dan hadn't forgotten anything in the room that he should come back from, but she didn't dare moan or make a sound. With a silent scream she finally released the pleasure in her body and collapsed on the bed.

She loved every moment of the orgasm but had to cover the evidence. She quickly put the dildo away in one of her drawers that only she used and quickly went back to bed. It was only then that she noticed that there was a big wet spot in the middle of the sheet, but she didn't have time to change it, because Dan had come back to the exhausted girl.

When Dan returned from the bathroom, he lay down next to his exhausted girlfriend with his hard manhood. Sophie lay in the middle of the bed on the wet spot so her boyfriend wouldn't notice. Dan lay tightly behind his girlfriend and hugged her from behind. His erection pressed between her round butt cheeks. Sophie sighed. After her previous intense orgasm, she wanted nothing more than to sleep and get a good night's rest, but as soon as she felt the throbbing heat on her skin, she went weak. As realistic as the fake cock Kristy had brought her was, it was lifeless. Dan's manhood, on the other hand, swollen with power, pressed hard against her ass. She could feel the throbbing veins and the hotness of it.

Dan then, in a sudden moment, placed his glans against her slit and, with one decisive thrust, penetrated her. His thick meat slid unimpeded to the deepest point, which amazed Sophie. She knew it was because just a few minutes earlier she'd had the huge dildo inside her. She expected this, but she didn't think it would make such a difference. Now she could barely feel Dan's big cock. The dildo stimulated places in a way that nothing had before, and compared to that, Dan's cock now felt small. But even if it was not small, it certainly didn't give her the pleasure it used to.

Dan experienced none of this, or at most that he was able to penetrate her more easily, without any difficulty. If he had thought about it, he might have remembered that something was out of the ordinary, but he attributed it more to Sophie being more than usually aroused. For Dan, there was no other feeling now when he was ramming Sophie's massive-dildo-fucked hole. He was glad that she was ready for him.

As Dan started to move faster and faster inside her, Sophie was enjoying it more and more, even if she didn't feel the tightness she usually did. She was undoubtedly enjoying her boyfriend's action. Dan cupped her breasts from behind and gently kissed her neck. She was moaning louder and louder and enjoying more and more the cock moving in and out of her cunt. This also got Jimmy's attention, and he couldn't believe that Sophie still had the energy to have sex with Dan after her previous orgasm. True, he had no problem with this either and began to jerk his rapidly stiffening prick again.

On the other side of the wall, the couple got more and more into it and kept going louder and louder. Sophie was no longer concerned with anything but the throbbing dick inside her. The feeling was not the same, but it had its advantages. It was a real cock.

"Oh yes, Dan! Come on! So good." She cried out as her boyfriend banged her hard. Sophie felt herself getting close but knew Dan needed more time. So she pushed Dan away slightly and faced him. With two hands she pushed him onto his back and mounted him in a riding position. He just let his girlfriend take the lead and waited for her to sit on his cock. He didn't have to wait long because Sophie immediately grabbed his hard member and pinned it straight to her slit. Without thinking, she sat into it and let the stiff cock fully penetrate her. She moaned loudly and enjoyed it as it filled her vagina. Dan watched wide-eyed as his girlfriend swallowed his cock completely without any difficulty, but he didn't care; he had no second thoughts.

'My God, Sophie must be extremely turned on.'

She then began to rock her hips and, unstoppable, approached her own orgasm. Dan enjoyed the way his cock moved in and out of her wet cunt and watched with pleasure as she took in every inch of him. He saw his girlfriend completely out of herself and thought about how much Sophie loved his cock and how much she enjoyed him fucking her. Dan didn't even have time to be surprised; Sophie's orgasm came so suddenly.

She fell onto her boyfriend's chest, screaming and shaking, but she knew Dan hadn't come yet, so she kept up the bucking motion. She wanted to hold back the catharsis, but the feeling of a real cock inside her, and the thought that not long before she had had an even bigger dildo inside her, caused her to fantasize about Jimmy fucking her. This image, however, brought her to the climax very quickly. She couldn't help it, but she didn't want to. Now her only goal was to satisfy Dan after she had had her second orgasm of the evening.

Dan, however, was now no longer letting her control everything. He gripped his girlfriend's buttocks and sat up in bed, holding Sophie in his lap as he began to move inside her again. Meanwhile, he placed a hot kiss on her lips, and they were lost in the dance of each other's tongues. Dan's cock was incredibly hard, and he felt it about to burst. He was trying to fuck her more than usual, and he couldn't understand why it wasn't having the same effect on Sophie now, but he didn't care.

He was also focused on his own pleasure and felt he didn't need much more. Besides kissing, he spent time with Sophie's round breasts. She cupped the perfect boobs and sucked the hard nipples. This turned them both on even more.

"That's it, baby! I'm going to fill your sloppy pussy. I'm going to cum inside you. I'm going to breed you."

That last sentence was very arousing to her, and true, she was on the pill, but it was still arousing to picture it. She hadn't thought of herself as aroused by it before. So the fantasy, and Dan's violent movements, made her start moaning again, and she couldn't decide for herself if her third orgasm was real or if she was just trying to pretend and show Dan that she could cum again, but she and the guy moaned out at the same time, and she could almost feel him filling her cunt with his hot jizz. She also moved her hips to milk his hard member.

In the last moments, their mouths pressed together, melting into one. They fell back into bed smiling, satisfied and happy, and Dan's mind replayed the previous fuck over and over again, but something else filled Sophie's mind. She wondered more and more what it would really be like to take in Jimmy's huge manhood.

The next morning, Dan left for university early, while Sophie was still fast asleep. He didn't have the heart to wake his girlfriend, even though he would have liked to cuddle her after the night before. It was Jimmy's day off, and although he had woken up early, he had been lying in bed for hours, with a different perspective, but he had last night on his mind. Listening to the couple, he came once more, and until they were silent, he put his ear to the wall to see what was happening. To his regret, Sophie no longer called his name when she was with Dan, but it was still arousing for him to listen, even though he couldn't see the scene. In the morning, he listened from his room as Dan left home, and as he thought of being alone with Sophie, his cock began to harden again. Then he was distracted by a noise and heard someone in the kitchen.

'I think it's time for me too to start the day.'

As Jimmy stepped out into the kitchen, Sophie had her back to him at the kitchen counter, preparing breakfast. She was wearing a pair of shorts and a tight top that highlighted her gorgeous shape, and the nerd's eyes lingered on her round butt cheeks for minutes. He felt his dick stir, but he couldn't disappear without a sound; she must have sensed something in that moment because she glanced back over her shoulder and smiled at him.

"Would you like some breakfast? I'd be happy to make some for you too." She offered. Since it was sudden to Jimmy, he could only nod and hope she didn't notice the bulge in his pants. But it was a vain hope, for the next moment her gaze rested on his crotch, and with a smile, she turned back to prepare breakfast.

'What the hell am I doing? I have a boyfriend, and I love him. It's not right to stare at his cock like that.'

She chided herself but couldn't help the desire.

Her pussy was still burning from the day before, but again she was filled with excitement as she thought of the huge dildo. She wanted to compare the size of it with Jimmy's. She heard him take a seat, and that reassured her a little. At least his hard-on wouldn't be so noticeable. She was grateful that her arousal wasn't as visible as the men's. They sat down across from each other and sat in silence for most of the breakfast. They barely spoke, each of them consuming their meals, lost in their own thoughts.

"I'm sorry if we were a little noisy yesterday. I still can't get used to having you here, and if I get so carried away..."

"Don't say anything. It's perfectly natural. If I had a girlfriend, maybe we'd be noisy too." The statement seemed oddly funny, but there was truth in it.

'Well, I'm sure if you fuck someone with that big cock, we'll hear it.'

She wondered.

"Though I guess you weren't just being loud when Dan was at home. I mean, you weren't shouting his name." Jimmy added with a smile, which made Sophie blush slightly.

"So you were eavesdropping?" That made Jimmy redden now, and no answer was needed. "No problem." She replied with a smile. "It's only natural that you're aroused and... I know you've never been with a girl before, and yes... I've fantasised about your cock... but you know, I have a boyfriend. It's just a fantasy, Jimmy. I don't want you to get carried away. I know you fantasise about me the same way."

"And then can't we... you know... like once before. In front of each other. You know. It's good to fantasise, but it's better to see it. Maybe we could help each other." Jimmy was right, and Sophie wanted this more than anything, but she didn't know how far she could go.
