Yes

Before Sophie could do anything, her girlfriend was already in the corridor outside the changing rooms, in her underwear, calling out for Jimmy. The nerd wasn't far away, but he couldn't hear what the girls were talking about. At Kristy's call, however, he snapped his head up and tried to keep his eyes off her in confusion, but he didn't have much of a say in it either, as she dragged him into the dressing room after her without a word.

"Er... well... what should I have to decide?" He asked, confused.

"How do you think this lingerie looks on us? This one or maybe that red lacy one?" Kristy asked defiantly, holding up the other one the girls had brought.

"Well, I don't know... this one is also very... sexy... but I'm sure the other red one would look good too." He said, still confused.

"What are you waiting for, Sophie? Try it on!"

"What? Now?" She was stunned to realise what Kristy was implying.

"Of course. There's nothing he hasn't seen before anyway. You don't have to go outside, Jimmy." She said with a smile as he started for the door, but her words froze the blood in his veins, and he didn't move. He just stared at the girls with his eyes wide open. It was clear to him that the girls had shared everything with each other, so he was sure that Kristy knew everything about what had happened between them. He took a big gulp but didn't move.

Sophie knew there was no point in resisting. So with trembling hands she began to remove her bra. Kristy was right; Jimmy had seen her naked before, and there had been more, but this was different. Her best friend was there, and that made her a little nervous. Nevertheless, she didn't stop and, of course, took off the thong she was trying on. Jimmy looked at her naked body with a lustful look, and something in his pants stirred. Sophie also began to relax and act more naturally. Then something happened that she hadn't expected. Her girlfriend started to undress, and she had to stop dressing and talk completely naked to Kristy, who was undressing next to her.

"What the hell are you doing?"

"Well... I'm trying on what I picked." She said with complete naturalness. "I know we haven't seen each other naked yet, but you know I'm a rather liberal soul. My man wouldn't mind at all. After all, we don't want to fuck." And without a word, she unhooked her bra and hung it on the rack. Her large, round 36C breasts caught the attention. They were visibly larger than Sophie's, of which she was a little jealous, but the brunette wasn't unhappy with herself. Jimmy, like a deer in the headlights, dared not move and, barely breathing, just stared at the breasts he was seeing for the first time in his life. Kristy was clearly stealing the attention from Sophie, but she didn't seem to mind. Jimmy, on the other hand, couldn't believe what was happening to him, and of course his cock was now pressing uncomfortably against his pants.

When Kristy took off her panties, exposing her beautiful female mound, the nerd had to adjust his erection. This did not escape the girls' attention. Jimmy gulped as he looked at the newly revealed snatch. Unlike Sophie's, it wasn't perfectly shaved but had a trimmed landing strip, which the guy thought looked quite erotic. Kristy then bent down to pick up the panties in front of her, but in such a way that the nerd could perfectly see the pussy lips between her buttocks in the mirror behind her. He swallowed hard, and his cock pushed even harder against his pants, which he had to adjust again, but that caused his glans to poke out at the waistband, which only his shirt hid from prying eyes. Jimmy's heart was pounding so hard he almost fainted. Kristy stared wide-eyed at the nerd's bulge and felt her pussy flood with heat. She dressed as erotically and slowly as she could, but Sophie was a little faster. Now she gave the spotlight to her bestie.

"So? Which is better? This one or the previous one?" Jimmy was silent as he stared at the girls. "So you're speechless. Then at least take a picture of us." With that, Kristy took her friend's phone and handed it to the nerd, who obeyed without a word. "Thanks, big boy. We'll send this to Dan. Maybe he'll be able to choose."

"What? What are you doing?" But there was nothing Sophie could do. Frightened, she looked at the picture she had sent. To her great relief, Jimmy hadn't been seen in any of the mirrors, but it was clear that a third person had taken the picture of them. She could only hope that her boyfriend wouldn't notice. "If Dan gets suspicious about this, I'll kill you." She told her girlfriend.

That's when the response came. 'You're unbelievably gorgeous. I like the lacy one better. And I'm sorry to say it, but Kristy's pretty hot too. Buy this one. Too bad I can't be there to see it in person. But, uh... Kristy doesn't mind if you send me pictures of her?'

"See? He doesn't find out anything." Kristy said as Sophie read the message. "You can tell him I don't mind either. And if I were single, I'd show him more. And add a winking emoji."

"Hey. At least don't flirt through me." The brunette protested playfully, knowing that her friend was just teasing her. But she couldn't get over the fact that Jimmy's presence didn't bother her that much. The boy didn't dare move, just glancing up at the girls as they began to undress again in front of him, quite naturally. His eyes darted from one girl to the other, catching another glimpse of bare pussies and round breasts. He thought he was in heaven. Of course, he was very pleased to be part of such a show.

Sophie found the situation strange at first but was actually excited by it and adapted to her friend's daring. She was ready to go when her phone rang. Dan was calling, so she excused herself and left the others. Jimmy started to follow her, but Kristy stopped him, still wearing only a thong.

"Not so fast. Won't you wait for me?" She asked, and Jimmy didn't dare to say no. He also didn't want to, because every minute he had with a hot, half-naked girl was a gift. "Well, I heard from my friend that you're... you're big... you know. And since you've seen mine, it's only fair that you show me yours." Kristy wasted no time in getting down to the matter at hand. Ever since the nerd had joined them, it had been all she could think about, but she didn't dare make such a move in front of Sophie, knowing that she would object. So it was lucky she got the call.

Jimmy froze as he watched her move closer to him. Without a word, she put her hand on his bulge and squeezed.

"Oooh! You must be very proud." And with that she pulled up the boy's shirt, smiling as she saw the glistening glans. But she didn't stop there; she unbuckled his belt and pulled down his trousers. Since they his cockhead already poked out a few inches above his waistband, it didn't take much to pull his trousers down, and now half of Jimmy's sizable cock was visible. Kristy slowly pulled his pants down until his heavy balls were also exposed. She looked into the nerd's eyes and then looked down to get a closer look at the big cock. Her eyes widened at the sight, and it looked even bigger up close. She stared at it with her mouth open and couldn't help but wrap her fingers around the thick shaft with one hand. "Fuck. You are really huge. I've never seen a dick this big before, but even the biggest I've ever seen doesn't come close to THIS." Then she gave it a few strokes. She enjoyed the throbbing heat that filled her palms and the hard manhood that almost exploded in her hand. Her pussy was quickly getting wet, and she knew she had to try this cock sometime. On the one hand, she envied her friend for being his flatmate, but she wouldn't have been in her place for the same reason. She knew how hard it would be for Sophie. She was so close to temptation, and yet she wanted to remain faithful.

"I bet you're always wanking that big cock thinking about my best friend. Don't even try to deny it." She declared defiantly.

"Well, um..." Jimmy didn't dare answer, but that was enough for Kristy to know the answer.

"I knew that, big boy. At least now you can play with me in your fantasy." She winked at him as she slowly stroked his big cock, now with both hands, and the tip was almost between her breasts.

"Too bad I have a boyfriend. So we better get out of here. Sophie might get suspicious of what we're doing after all this time." And with that, with difficulty, she let go of the throbbing member that cried out for relief, but she really didn't want to risk it.

"And can we just... you know..." He tried, but she didn't want to push the boundaries.

"Sorry, sweetie. Maybe another time."

She took one last look at the dick and then, after getting completely dressed, left the shocked nerd in the dressing room. Kristy knew what she'd be thinking the next time she would masturbate or fuck with her boyfriend. But she wasn't ashamed of it. It turned her on to think about the monster. But she didn't want to hurt her best friend. Jimmy was her prey, and if she wanted to share it with her, Sophie would tell her. It must be hard enough for Sophie; she didn't want to intrude into her life. She'd rather wait and see what develops and then bring up the idea. In the meantime, she knew her friend was telling the truth, and she would always look forward to more juicy stories.

Sophie hadn't suspected anything when she ended the call; Kristy had just returned, and Jimmy had followed shortly after, but his tent was still a sure sign that he was very excited about what had happened in the dressing room. The girls were amused but not surprised; after all, none of their boyfriends had ever been in the same room with two naked girls. The nerd's excitement was natural.

Jimmy, however, didn't want to be around them any longer, so he excused himself to go about his business of buying video games, but before he did, he made a quick detour to the mall bathroom, where he quickly jerked off to relieve himself.

The two girls walked around the mall for hours, talking about their adventure with the nerd. Kristy kept quiet about her private little affair, but of course she couldn't help but fantasise about his huge dick.

"Oh, Sophie! We have to have sex with him one day! Imagine what it would be like for him with two girls. Really! What it would be like to lose his virginity like that. It would be the experience of a lifetime for him, that's for sure."

"Stop it! You're talking about us both being unfaithful and cheating on our boyfriends."

"You're the one who was actually working on Jimmy with your ass this morning."

"You're right, but..." Sophie began. "At least it's not cheating. I mean, we're not fucking or anything."

"Is that what you keep telling yourself? You don't have to make me believe it; I probably would have done the same thing, but think about it. How would you feel if another girl gave Dan a hand job, for example? Would you feel he was cheating on you?"

"That's totally different... I mean, you're probably right. And, you know, I thought I was going to end this thing with Jimmy, but then he came into the bathroom and..."

"You couldn't resist him. I totally understand. But don't worry. It'll be our secret. And Jimmy's too, but I don't think he'll say anything. Just remember, you're one step away from giving him a blowjob. And two steps away from getting fucked. If it hasn't already happened." She said with a grin.

"Nah, I didn't do that." Sophie defended herself. "But you know, I've often wondered what would happen if I suggested to Dan that we involve Jimmy. I don't think he'd go for it, but who knows. Ugh. I don't know what to do. Should I follow my heart and my mind, or should I let my desires guide me?

"Well, girl, I don't envy you. Well, yes and no. You have to know. I can't decide instead of you. But I guess a little adventure shouldn't be a problem. I mean, you're not married yet, you know. That would be different. But you're young now; why get attached to one man? Even if he's the one you're going to spend the rest of your life with, you could still miss out on an adventure you'll remember forever. And you could do something with Jimmy that no one else could do. I know I'm speaking against Dan, and I really like him, but... When we lived together, you know, I fantasised about him, but Jimmy... You know what I mean; I just... But it's just my opinion, and you don't have to do what I would do. I know you have a different nature.

"I understand what you're saying, and thank you for being honest with me. It means a lot to say what you think. But I still don't know what to do next. The problem is that when I make up my mind to do something against it and then I see again... THAT, I get weak, and all I can think about is wanting to feel it again."

The girls talked for a while before saying goodbye, and then they both went home. Sophie continued to think about the nerd and his dick because of the day's events, but Kristy also stuck her bug in her ear and played with the idea of a threesome. She was sure that Jimmy would be extremely hard if the two of them enjoyed his huge cock, both of them naked. She knew that her best friend possessed some outstanding physical attributes that would have attracted the attention of any man. She imagined both of them kneeling in front of the nerd, them getting Jimmy's hot cum in their faces and then exchanging a passionate, hot cum kiss. She could feel her pussy starting to get wet, so she couldn't help but lie back on the bed and finger herself wildly. She came very quickly, fantasising all the while about having a threesome with Jimmy and Kristy. She was excited at the thought of imagining something her boyfriend wanted but had never been able to get. And now, in her fantasies, she was imagining herself in that situation with another man. As she thought about it, she gasped and screamed loudly just as the front door opened and Dan arrived home.
