Hey babe!
You walk into the apartment after a long day at work. You see Harley, your girlfriend wearing clothes as if she was about to go out for the night. "Hey babe." You reply wearily as you start to put things on the kitchen island. "You going out?"
I'm just gonna meet some girlfriends at a bar! You should come with me! We could... have fun and maybe find some hot guy to bring back home with us? :P Just kidding baby, I know how busy you are but it'd be really nice if we could spend sometime together. And also, what about the sex thing tonight? You didn't forget our promise right? It's been so long since we last did it...
"Ha ha, very funny." You say, "I think I'll pass you up on the bar, I'm absolutely exhausted from work today, but you go and have fun with your friends. I can plan a date night for us another time okay? I'd love to spend some time together." You walk over to Harley and give her a peck on the cheek. "Have fun baby." You say and walk to the fridge looking for something to eat. You seemingly ignored the sex thing that Harley mentioned and Harley decided not to bring it back up again. She was definitely a little hurt however and her sexual needs haven't been met.
Oh... Okay baby. Well, if you change your mind you know where to find me later. I love you so much and I'll make sure not to stay out too late okay? Just let me enjoy my time with the girls for a little bit. You deserve it as well, you work so hard!
On that note Harley left the apartment and met up with her friends at the bar. At the bar she laughed and drank with her friends, talking about whatever gossip they had. Deep down however Harley was horny and was disappointed that you wouldn't join her tonight. Harley talked to her friends about you, and they egged Harley on to find someone at the bar.
Harley couldn't help but feel a little annoyed with herself. She knew she shouldn't have brought up sex earlier. Sometimes she was just so needy and clingy. But as the night went on and she had more to drink, her mind started to wander back to you. She tried not to stare at the cute guys around her, but it wasn't easy. She knew if she slept with one of them, she would feel guilty about betraying you. But goddamn were they sexy! As Harley downed one drink after the other, her mind started to get cloudy, and she started to feel hornier. Eventually a group of guys came over to Harley and her group of friends. A couple of her friends were single and they decided to let the guys join their group. More drinking and flirty ensued between them all, and eventually in the blink of an eye, Harley and her friends were all together at some frat house that the group of guys belonged to. The sexual tension was heavy in the air, and everyone knew what was about to happen. Harley and her friends were about to have a gangbang with each other.
As the night wore on, the group of guys led them upstairs to one of their rooms. It was clear they were all horny and eager to get laid. They pushed the girls onto beds and began taking off their clothes. Harley found herself lying down next to her friend, wearing nothing but her panties. She could feel the weight of a guy pressing against her thighs, his erection clearly visible through his boxers. As they all paired off, she heard moans and gasps coming from around her, as people began to fuck. Harley closed her eyes for a moment, trying to concentrate on how good it felt. One of the guys leaned in close to her ear and whispered dirty things while he fucked her mouth, and another started playing with her clit, causing her whole body to shudder. It was intense and exhilarating but somehow she couldn't help feeling guilty about cheating on you. However Harley remembered that you forgot about the promise of sex tonight, and her guilt disappeared. She had needs and if you weren't going to satisfy her needs, then she had no choice but to get her needs satisfied elsewhere.
The feeling of being filled was incredible and she could feel herself getting closer to climaxing. The more the guys around her moaned in pleasure, the hotter it became and before she knew it, she came, her body shuddering with each wave of ecstasy that swept through her. Her cheeks flushed as they finally finished, leaving her and her friends sprawled across the bed, breathless and satiated. For tonight at least, Harley had forgotten about being hurt or guilty. All that mattered was the pleasure she'd just experienced.
