Kristy

As promised, Kristy went to visit her best friend, but she didn't say anything in advance. She knew Sophie would be home, and as she didn't have any plans, she thought they could have a girls' day out. When she arrived, no one answered the door when she knocked, and as she was familiar with the flat, she went in. Luckily, Dan had left the front door open, so she didn't have to worry about getting in, although she still had her keys to the flat. She found her old room open, and as there was no one in the house, she figured the nerd must have gone somewhere. When she entered Sophie's room, she found no one there either, but she heard water running from the bathroom. She was sure that Sophie was there, so she was prepared to follow her without a doubt. The girls were never shy with each other. She was about to enter the bathroom when she peeked through the crack and heard the sound of talking. 'Maybe Dan is home after all, and they're taking a shower together.' She couldn't think of any other reasonable explanation, so she screamed in surprise when she saw her best friend with her hands up against the wall, giving an assjob to a very skinny guy with a huge, thick cock that looked very out of proportion to his body. 'So Sophie wasn't lying. He's fucking enormous.'

Kristy didn't want to get caught, but she couldn't take her eyes off the nerd, and the sight made her heart beat faster. Kristy considered herself a true size queen; lately she'd been lucky with men because they were blessed with large sizes, and she'd become addicted. But Jimmy's size stunned her even more.

Sophie moved her ass with practiced moves on Jimmy's sizable meat, and it was obvious that he was having a hard time holding it back.

"Come on, Jimmy. I know this is what you want. Come on, cum for me. Shoot your load all over my ass. Mark your territory."

"We should stop Sophie... aaah! You know... Dan..."

"Come on! I jerked you off before. This is no different. Only now, I am doing it with my bum. We're not fucking. It's not cheating." She said, although she didn't believe what she was saying. This was definitely in the category of cheating, but Sophie dismissed these thoughts. She just focused on the nerd's dick. She really enjoyed the hard and hot member as it slid up and down her slit, teasing her clit. But she needed more time, and now she wanted to give Jimmy the pleasure.

"Aaaahh! Shiiit! I'm cuuuummmiiing!" The nerd's skinny body shuddered, and his load shot out with great ****, which went first onto the girl's back, then Jimmy suddenly gripped his thick cock and aimed the rest of it at her butt. It was an incredibly erotic sight for him to see the sexiest part of her body covered in his cum. Sophie smiled at the guy over her shoulder and teasingly shook her bottom a little against his still hard cock. She felt the hot juice slowly flow down and between her cheeks, down her asshole and up to her cunt, where it dripped onto the floor. And at tht moment, she also reached her climax and with a loud moan she also came, her legs trembling as she finished herself off.

"Mmmm! Fuuuckk! It's so goood! Aahhh!" She cried as she continue to rub her clit covered with the nerds cum. When she calmed down, she still smeared the hot jizz on her pussy which cause her great arousal.

"I think we need to clean ourselves up." She said, and without a word, she soaped the nerd's cock and washed the remaining cum off it.

"Now it's your turn, sweetheart. My back will be hard to clean for me." With that she turned seductively and waited invitingly for Jimmy to wash her back. With trembling hands, the nerd soaped her up and washed his own sperm off her back. It was an incredibly erotic experience for him, although he wasn't entirely comfortable with it. "Lower, sweetie. There's more." She instructed, so Jimmy was **** to do so, and although he really enjoyed touching Sophie's bum, it was a bizarre situation. With her encouragement, he gained a little confidence and rubbed her firm buttocks with more assurance. He didn't dare reach between her asscheeks, but Sophie didn't ask him to. It was also a big step to let the nerd touch her body, and that little touch made his cock hard again.

Kristy watched the scene with her mouth agape, unable to believe what she was witnessing. Her innocent bestie was touching her roommate's huge cock behind her boyfriend's back. 'Why don't I ever get involved in situations like this? I wish it had been like this when I lived here. How much fun we could have had together. But why am I talking in the past tense?' She began to think, and an idea took up more and more space in her head. When she looked at the couple, they were already towelling off, and not wanting to be caught, she quickly went to the front door and waited a while. She didn't want to embarrass the others, so when the way was clear and she heard Sophie coming out of the bathroom, she greeted her as if she had just arrived.

"Hello! Anyone home?" Sophie had just come out of the bathroom in a towel, so she greeted her friend. She looked a little embarrassed, but anyone who didn't know what had happened a few minutes earlier wouldn't have noticed. Kristy also tried to act natural, but the wetness in her panties kept reminding her of what she had seen and assuring her that she wasn't dreaming.

"I'll be dressed in a minute. Come to my room in the meantime." Sophie invited her friend, who followed her inside. As the door closed behind her, Kristy couldn't resist asking her friend a question.

"You weren't trying to hide that little game you played this morning from me, were you, you little slut? I had no idea you were telling the truth about Jimmy. He really does have a monster cock."

"What? Why...? How did you...? I didn't... You were spying on us!?" Sophie slowly put the picture together.

"Look. The door was open, I heard you in the shower, I wanted to come in, but... I got stuck on something really big." She said with a smile. "You little whore. No wonder you can't resist. It would excite my imagination too. Don't worry. I won't say a word to Dan." She reassured the brunette when she saw her frightened look. "You have to tell me how it feels. Has he fucked you yet?"

"No... no, I just... jerked him off. He didn't even touch me."

"You JUST jerked off. Well... I saw it differently. He was fondling your firm little bum very sensually, baby. Well, I'm not judging you. I'd probably do the same."

"No. You would have fucked him already." Sophie finished, now a little relieved.

"OK. You're right." Then they laughed about it. Sophie was lucky to have a friend like that she could talk to about anything. They talked for a while about her experience with the nerd's cock and then wondered what they were going to do that day. Kristy was very turned on by the nerd, but Sophie cooled her desires a bit. She needed some fresh air, so they agreed to go shopping at the mall.

They were about to leave when they met Jimmy at the entrance.

"Where are you going, big boy?" Kristy asked with a smile and a very obvious hint. Sophie tried to shut her up, but the nerd knew what she meant. This made him blush a little, and he answered confused.

"Um... I'm... just going to the video game store."

"Great. We're going to the mall too. Come with us." The two roommates didn't even have a chance to object; Kristy had already decided the question. Jimmy followed the girls, a little timidly. He tried to hide his growing bulge, which hadn't escaped Kristy's notice. Sophie walked nervously beside them. 'What's going to happen now?' She knew her friend and was afraid she was going to cause some embarrassing moments.

At the mall, Jimmy started to go his own way, but Kristy stopped him.

"Do you want to come with us? You know, we want to buy some clothes, and we need a man's opinion."

"Well... after all... I guess I could go." She replied shyly.

"Then let's go to the lingerie shop. Sophie wants to buy some sexy lingerie to impress Dan. But I could pick something out for myself." She winked at the nerd.

'Is she teasing me now?' the nerd thought, not believing that he was now surrounded by not one but two beautiful girls. He didn't really dare contradict them, so he went with them, not knowing what to expect or how to help them. They went from shop to shop, and Jimmy just followed the girls as a shadow, not really daring to speak to them. He was more relaxed with Sophie, but the new girl made him feel embarrassed again. In one shop, Jimmy lingered outside the dressing rooms while the girls went in together to try on clothes. Kristy was trying on a casual but sexy pair of lingerie.

"So what's it going to be? Do you think we should invite him in and show him what we're trying on?"

"Don't be silly. I'm not going to invite him in."

"But he's already seen you naked. And I'm not shy."

"Even so. There's not even enough room for the three of us. I would rather ask Dan which one I should choose."

"Fine. Come on, babe." With that, Kristy took Sophie's phone and took a selfie of both of them with their backs to the mirror, getting a perfect picture of their round butts, and immediately sent it to Dan with a message.

'I miss you, sweetie. I'm sorry you're not here with us. You could help us vote. :* ;P'

"Hey, what are you doing? Did you seriously just send my boyfriend a picture of us together in lingerie?"

"Come on. He's already seen me in a bikini. This is no different. And by the way..." She was speechless as she noticed the nudes she'd sent earlier in the couple's conversation history. "You don't have a word, darling, after sending pictures like that to your boyfriend. Dan's a lucky bastard."

"Now seriously, give it back. This is private." Sophie's phone beeped then.

"What did he say?" Sophie sighed but knew there was no point in arguing, so she read it out.

'Aww! I miss you, sweetie. Is that Kristy? You two are sexy as hell. I'd love to help. Now you've got me working with a hard cock. It'd be best to get it free. Too bad I can't do it here in front of the others. ;) <3'

"See? I bet he'd be up for a threesome."

"Dan? Definitely. He's always had a thing for you. Even when you were living with us, the subject came up between us. A couple of times I noticed his dick was hard when you were in your pyjamas or a sexy dress."

"Oh! Too bad you didn't bring up the idea of a threesome. And by the way, I noticed his bulge a couple of times too. It was sexy. I wonder if we can get the same effect on Jimmy."

"What...? Hey! No! What are you talking about? Wait a minute!"
