But it's also really hot. And about to get hotter.

Allison is the first to break the awkward silence. "Well, you should probably get dressed now." She sounds hesitant and slightly out of breath. It's strangely comforting that apparently you aren't the only one turned on by this scene. Gwen reaches slowly for the panties she left on the floor, right next to the ones you borrowed from her yesterday. You must have missed them somehow when you were cleaning up earlier. Unless... you glance over to the dresser where you left the rest of the outfit neatly folded. Except now they don't look so neatly folded. Did Gwen...?

Before you're able to finish that thought, and before Gwen is able to finish putting her underwear back on, you're both interrupted by someone saying "wait." You look back and forth between your girlfriend and your sister, but they're both just staring back at you. Hold on a second... that was you just now! Why did you say that?

"It's just... we interrupted, and that's not really fair to Gwen... because she didn't really... you know, and it wasn't really her fault that..." you babble aloud, struggling to find a decent answer to your own internal question. Eventually, you give up - you're too horny to make up excuses. "Oh, fuck it!" you exclaim, and you tackle Allison into the bed and start pulling off her clothes.

"Sarah, what are you doing?!" Allison asks in a panicked voice. Still, she isn't doing anything to stop you. You can tell she wants this too.

"We're going to give Gwen here a little show," you answer. You glance over to Gwen, who's clearly already given up on redressing. She blushes, but doesn't look away.

"But she doesn't want to watch her own sister have sex, does she?" Allison looks to Gwen as she asks this, but Gwen doesn't answer. Either she's too far gone to talk about it, or she just isn't comfortable talking about it. You don't answer either, because now that Allison's panties are off your tongue has better things to do than answer questions.

You've eaten Allison's pussy before, but this time is different. For one thing, you never had an audience before, let alone your own sister. That isn't the main thing that strikes you as different now, though. It's more like her pussy itself has changed. Now that you have one yourself, now that you've experienced the kind of pleasure you can give to her, it's like you understand what Allison needs in a way you never could before. It's not like you can just do for her what you'd want her to do to you - your bodies are still a bit too different for that - but you're much better at finding what works for her. As a boy, you really had to think about it, but now it's almost intuitive. You hope that your new talents will carry over once you get your old body back. Though you aren't sure who you'll be able to try them out on...

To distract yourself from that train of thought, you reposition yourself slightly. Now your tongue can reach a bit deeper, and perhaps more importantly, you can look Allison in the eye as you pleasure her. She smiles at you, then reaches down and tousles your hair. You acknowledge her gesture by flicking her clit with your tongue, and the next thing you know her hand is pressing against the back of your head as if to bury your face inside of her. It's a bit uncomfortable, but you'd gladly endure far worse to see the look on her face right now.

Finally, curiosity overtakes you, and you pull Allison's thigh down to the bed so you can peek at Gwen. She's masturbating again, like you expected. Her gaze flicks across Allison's body before she locks eyes with you. With her looking down at you, moaning and panting in pleasure right alongside of Allison, it's almost like you're eating out two gorgeous girls at the same time. And she really is gorgeous - there's not much point denying it anymore. While she's looking at you, she apparently decides to finally answer Allison's question: "I wouldn't want to watch my brother have sex... but I don't see him anywhere. I just see a really hot girl."

Suddenly your vision of Gwen is blocked by Allison's arm as she pulls your sister in for a long, sloppy kiss. Fuck, that's hot. You delve into Allison's folds with a newfound urgency, more than a little motivated by the selfish desire to finish her off so you can get some relief for yourself. Your hand found it's way between your legs a while ago, but it's hard for you to get a good angle, especially since you're still wearing pants. It doesn't take long for Allison to cum. She hardly gets a chance to disengage from Gwen's lips before shuddering through her orgasm, their faces still only inches apart.

Almost immediately you're out of the bed - you can't get your clothes off fast enough. You definitely won't be wanting to put this pair of panties back on - they're sticky with your juices. Allison moves in the bed, inviting you to the space she was just in. Still, you're suddenly having second thoughts, as you can see Gwen looking at you expectantly. If you stop now, or maybe just ask Gwen to leave, it still definitely isn't ****. Are you really ready for this to go any further?
