We keep it a secret between us girls.

Oliver was dancing with Amara and watching the whole scene unfold with wide eyes. The girls allowed themselves to be fondled and groped by the guys, allowing their hands to wander all over their bodies. Some even kissed the girls while their hands were under their tops or up their skirts.

It wasn't long before he noticed that some of the guys took things further. He saw a few fingers going inside the girls' underwear. He also saw one guy unzip his pants, and then he watched in disbelief as the girl he was dancing with dropped to her knees, pulled out his erect penis, and began sucking it off. The woman's head bobbed again and again while the man groaned in pleasure.

Oliver looked around and realized that similar things were happening all around them. Some of the couples were still dancing, but many were now fucking or giving oral sex right there in the middle of the dance floor!

Looking at his sister, he noticed that she had a wide grin on her face. She was enjoying this!

"What the hell, sis?! What is going on here?" He shouted, trying to make himself heard over the loud music. "Isn't this place a little too crazy? Do you also do stuff like this? With random guys?"

Amara laughed at his reaction. She wrapped her arm around his neck and pulled him close to her. Her large breasts were pressed against his chest, and her mouth went to his ear. "Yes. This is my favorite place to come and have fun, where I can act wild and get a good fuck." She then kissed his cheek. "Don't worry, Ollie, I'm not a slut, but sometimes I just need to relieve some stress when Jack fails to please me. It doesn't mean that I come here all the time, though. Only when I feel like I need it, like once or twice a month."

Oliver stared at her, still trying to process everything that was happening. "But this is... This is not normal! This is not what a nightclub should be like!"

"Yes, it is!" She replied, her voice louder now, almost shouting. "Look at all the people around us, enjoying themselves, having fun. That's why this place is so popular. Everyone knows that if you want a wild time, then this is where you should go." She looked at him with a mischievous expression. Her eyes seemed to sparkle, her lips curved upward in a playful smile. "Do you think I'm a slut for doing something like this? Would you hate me if you saw me getting fucked by random guys?"

Oliver swallowed hard. His sister was very sexy, and he would never hate her no matter what she did. "No, I won't. You're my big sis. You can do whatever you want, but I don't know about others. Won't your boyfriend find out that you come here to get fucked? What if he finds out that other guys are fucking you?"

She giggled and then put her hands on his shoulders. She leaned forward until their faces were almost touching. Her breath was warm on his skin, and he could smell the alcohol on her breath mixed with the perfume she wore.

"You're so cute when you worry about me, Ollie," Amara said. Her words were slurred, a clear sign that she was drunk. "But Jack won't find out. We keep it a secret between us girls. All of my friends here tonight have boyfriends too, and their partners have no idea that we visit places like this from time to time. Isn't it great that we can still have fun without risking our relationships?"

Oliver didn't know whether to be relieved or disappointed by her answer. On one hand, it meant that she was being safe and responsible, but at the same time, it also meant that she was cheating on her boyfriend. 'No, it's not like that. It's just a bit of fun, and she's doing it because her boyfriend can't satisfy her in bed. It's not her fault that she needs to come here to get what she wants.'

"Okay, I guess," Oliver replied, still feeling a little uncomfortable about the whole thing. Then he asked, "But why did you bring me here? What did you expect to happen when we came to this place?"

Amara smiled again, and this time her expression was filled with lust. "Because I want to have sex with you, stupid. At first, I was just planning to pick someone up, but when you asked to tag along, the idea of having sex with my little brother was too tempting to pass up. And don't worry, I won't try to seduce you. If you want to do it with me, just let me know, and if not, then you can choose any of my friends or one of these other girls on the dance floor. Maybe you can even go for two or three of them at the same time."

"Do you think I would let you get fucked by another guy in front of me?" Oliver grabbed her by the waist and pulled her against him, causing Amara to gasp in surprise.

"Now that I am here, you will have sex with me and no one else tonight. Do you understand, big sister?" Oliver whispered in her ear, squeezing her ass. "If you want to relieve your stress, do it with your little brother, and I will make sure to satisfy you."

Amara bit her lip and smiled at him. She wrapped her arms around his neck, her body pressed against his. Her breasts rubbed against his chest, her nipples hard and erect. "Oh, really? Are you going to take responsibility and make me cum over and over again until I pass out?"

"Yes, I am," he replied, leaning forward to kiss her neck. His cock was rock hard and pressing against her belly. Amara giggled as she felt it, and she moved her hand down to stroke his member through his pants.
