But your body - your body's telling you... maybe?

You don't like this at all. Nothing's right about this. The sight of Gracie tied up like this, definitely against her will... you're sure Alex intended for it to be sexy, is all you can say. But you can't shake the awful feeling that you'd be violating another person. Even if that person did see you and immediately clock you as a target. You glance over to Alex, looking for some sort of moral advice... and she only stares as if to say "Well, go on. I'm waiting". This feels awful.

On the other hand... your conscious mind may be rejecting this outright, but the more primal part of you is a bit more receptive. For all the nastiness you got from Gracie, she does have a very shapely butt now that you're getting a good look at it. And the way that her arousal is making her thighs glisten makes something inside you want to fulfil it. Before long, you find yourself erect in your skirt, approaching Gracie with trepidation.

"Are you sure you want this?" you ask, as you feel your upper body trembling once again. "I don't want to do something that you don't want..."

"I really want to do it~" Gracie whines, moving herself back and forth as best she can in her position. "She got me worked up and didn't let me come... I need you, Rosie..."

As you drop your panties and lift your skirt, you take a deep breath. In the conflict between your morals and your desires, the latter is about to win out. You're attracted to Gracie, and she seems to be really enthusiastic about the idea of doing it. Plus, Alex is watching. You don't want to disappoint her.

And so, you slide in to Gracie, your hips squishing into her backside.

You're almost doubled over because of how tight she is. The feeling of Alex's pussy around your member was enrapturing in itself, but this is something else. Between that, and the way she moans from taking you inside her, there's no doubt how she feels about this encounter, no matter how much your thoughts nagged you before.

And so you move. Being ridden by a woman is an entirely different experienced to doing the moving yourself. You have much more control, more power. You're not sure you trust yourself with this level of power, but the feeling of pleasure rushing from your tip, down your shaft, and all through your body, means that you're not going to complain at all.

Gracie certainly isn't complaining. She did the talking on her sister's behalf earlier, but she's somehow even more of a loudmouth when having sex. She seems to be begging for more, but any attempt at words is reduced to incoherence. She really must have been stimulated before you got here. You're not particularly experienced, and not particularly good at it, as far as you can tell, so... this is the only reason.

It's not long before it's close to being over, and you're once again doubled over, feeling yourself twitching inside Gracie, knowing exactly what happens next. "I'm almost there... Where should I..."

Gracie is apparently struggling to speak the words of response... "Please... Inside me... You're gonna make me...!"

And mere milliseconds later, you do what she says, holding on tight to her hips as you burst inside her. The sensation is so intense, your voice is going ragged and your fingers clutch on to her tight. For a moment, your hearing, and everything you can see except Gracie, disappears..

But when you come back to, everything is back. The bound girl under you. The pouring rain, bouncing off the window outside. The splatter of some sort of liquid under your feet. (You won't process just yet that this is your first time ever bringing a woman to orgasm, and it was with Gracie Tayt of all people. That's not what you're dwelling on.)

And, of course, the realisation of what you've just done. You've exploited someone, no matter how much they ended up liking it. And even though your misgivings were right there, telling you to up sticks and run, you went through with it. You're really no better than scum. And Alex? She not only didn't stop you, she encouraged it all.

A feeling of sickness rises in you, as the sound of thunder crackles around. Pulling up your underwear, you rush back to your dorm, from where you don't emerge for the rest of the day.

You wake up to several texts. Just like the one yesterday, they're from Alex.Rosie?

Rosie what's wrong?

Was it something I said?

Please answer

Rosie are you still there?

You stop looking, turn off your phone and stow it away somewhere you can't see it. You're lucky today is a weekend day. You couldn't stand to be next to Alex in class after what happened in the storage room. It feels disgusting, what you did. And what she did to make it happen.

So much for a friend, huh?

You get in the shower (only looking down the whole time), get dressed and head out. There's probably some extracurricular activities going on. You need a distraction. Who knows, maybe you'll find another woman who'll butter you up and then convince you to hurt someone else.
