You should

Taking a large sip of your beer, you decide you should just go for it, before it's too late. You make your way through the heavily partying youth. When you reach your destination, you announce yourself, purposely ignoring Kevin;

'Hey girls!'

The girls both look at you, happy that you're there. Especially Jen, who's hoping you're here to save her from this horny couple. But instead, Sarah steps away from Kevin and embraces you. With her left hand she pinches your butt and drunkenly says;

'I'm so happy you're here! Let's partyyy!'

'You're enjoying yourself, I see,' you say, maybe a little too begrudgingly.

'Oh, yeah, that,' she says, a naughty smile on her face. 'You may not know this about me, but I get super horny when I'm drunk.' She gives you a wink, sending all your blood rushing to your downstairs area.

'What a coincidence,' you joke. 'Me too!'

She laughs. 'You're so funny! Dance with me!'

She lays her arms over your shoulders and starts to swing her hips and her head too, making her hair sway beautifully. You grab her sides, and start to dance with her. You're not a very good dancer, but the alcohol is making you feel confident. You slowly move your hands down towards her hips, but suddenly two hands appear there. It's Kevin again. He's moved back to grinding her again. It's like he doesn't care that she's dancing with you now.

Sarah bites her lips when he does this, and moans.

'He's got such a huge hard-on,' she tells you. 'I love it.'

Maybe it's the strange situation, or maybe it's the alcohol, but you tell her;

'I do too. You're so beautiful, Sarah.'

She looks at you, with her beautul smile and a drunkedly dazed look on her face. You can't help yourself anymore, you kiss her, on her beautiful, kissable lips. And she kisses you back, just as passionately as you. Her mouth tastes better than you could ever have imagined, even with all the alcohol.

You sincerely hope Kevin takes the message at this point. But when you finally look up, he's still there, humping away as if nothing has happened. And even worse, when Sarah stops kissing you, she turns her head around and kisses Kevin. Just as passionately as she kissed you.

And just when you think things can't get weirder, she moves her left hand and grabs your raging hard-on through your pants. She massages it a little, making you almost cum. And when she feels how big it is, she turns around to tell you;

'Wow, you weren't lying!'

You just smile at her, unsure of what to say.

'Hey! I've got an idea!' she continues. 'You've got the keys to the office right?'

You nod.

'How about we take this upstairs?' she asks excitedly.

'With him?' you ask, nodding at Kevin.

'Yeah, ofcourse!' Sarah says. 'Come on! It will be fun!'
