As the two of you continued your erotic session, Sunset remained in your closet waiting for a chance to escape without being caught by Aria. She had the door slightly open and watched as it all transpired. Noticing that the potion worked, she gave a silent sigh of relief. 'Thank Celestia,' she thought, 'looks like the potion had a delayed activation. I'll have to tell Twilight about this.' Her opportunity to leave will come sure enough, however, with Aria's high stamina, and your newfound stamina recovery, it might take a while for it to show itself.

It also didn't help that she was getting turned on, watching her friend rut the lust-crazed siren that is your girlfriend and one of her former enemies. A blush started to show on her face as she watches. It seems so wrong that she's watching the two of you getting so intimate with each other, but her hormones were starting to get to her. The moans she kept hearing from Aria was not helping either. " Oh yeah! Keep at it, Anon!" the purple siren moaned with pure ecstasy. Something which Sunset was starting to crave herself.

Dirty thoughts were forming in her head, scenarios of her with someone giving her the same arousing sensation that Aria. Preferably someone who would love her as much as you love Aria. Someone that would caress her body and make her squirm due to the intense pleasure that person would be giving her. Her nether region started to heat up as she can feel her panties getting a little wet. Watching the two of you rut, hearing the moans of the siren, and the thoughts in her head, it was all becoming impossible to ignore. It's almost as if she was going through her own heat cycle.

One of her hands moved down under her skirt and started rubbing her lips over her panties. She bit her lower lip to suppress her moans. 'This is so wrong,' Sunset thought as continued watching you mate with Aria while pleasuring herself. 'but I just can't help it.' Her other hand then snaked its way up under her shirt and fondle one of her breasts. Her breathing was becoming uneven from the self-pleasuring.

As for You and Aria, you've just finished round who cares anymore. The two of you were laying next to each other nearly exhausted from all the sex. Aria, still drunk with lust, looked at you with the same lustful smile. "So Anon, one more round before we call it a night?"

You gave a tired smile and nodded, "Sure, I think I can go for one more." It's fortunate that she can still get tired despite her high stamina, you can feel the effects of the potion starting to wear off. Hopefully, it'll last for this final round. Aria climbed on top of you and already have herself positioned over your shaft, though it may not be as hard as it was before, it was still good to go. Wasting no time, she lowered herself until she was at the base of it. As she let out a moan, she started grinding against your pelvis, earning some groans from you. She then leaned forward to your face and locked lips with you. You moaned into each other mouths as your tongue intertwines with each other. While you were making out, your hand reached over to her rear, each one grabbing a handful of her cheeks. The siren separated from you to let out a moan of delight, then looked down at you with a lustful smile.

"Let's try to make this one last." You don't see the reason why since you two are going when you wake up, but you didn't bother asking. It was probably her heat talking. Her hips started moving slowly up and down, and you were able to match her movements with your thrusts. The rhythm of your movement then slowly increased in speed as you groaned, feeling your member slid inside her back and forth. Despite doing this for so long, her insides are still tight. Don't know how, but still not going to question it and continued what you're doing.

Meanwhile, Sunset continued watching you two while trying to keep quiet in your closet. Though, she wasn't making it easy for herself. Her breathing became rapid as her face was heated up. Her heart rate was racing in her chest and the moans that were threatening to leave her throat. Plus, one of her fingers was inserted and pumping inside her. The ecstasy made her once bit her lips to suppress another moan. If keeps this up, she'll blow her cover. But she can't control herself. She inserted another finger as she watches you play with Aria's breasts, provoking more moans from your siren girlfriend as she continued bouncing on you.

"Anon!" Aria moaned, "I'm close!"

"Me too!" you grunted as you grabbed her hips and went faster.

'I think I am too!' Sunset thought as a third finger slipped in. Her fingers then increased their speed as her climax approaches. 'Sweet Celestia, this is getting too much to handle!' You all kept at it until you've reached your limit. Then it hit hard, and you all let out a loud moan as you all released, even Sunset as hers escaped her throat. Once she calmed down, she leaned against the closest wall to support herself since her legs weakened from that climax, all while trying to even her breathing.

You and Aria adjusted your position on the bed so you can rest comfortably for the night. "Wow," Aria said with a smile, "this was so unexpected. Before you were so tired that you can hardly satisfy me, but now you're suddenly full of energy."

You smiled back, "I guess I'm just full of surprises."

"Yeah. By the way, did you hear something while we were having our moment? Because I'm pretty sure I heard someone else moaning."

Sunset tensed up at what she said. Her eyes widen with her pupils dilated, and one of her hands covered her mouth. She didn't realize how loud that moan was. 'Oh no, I'm so busted!'

You almost tensed up as well, but you kept calm and tried to play it off. "I'm sure it was just an echo." Wow, you are bad at lying.

Aria raised an eyebrow, "I doubt that it was an echo, it didn't sound like either of our voices."

"Well it's late, so do you really want to talk about, or do you want to rest up for the morning?" You then move one hand down to her rear and the other to one of her breasts and squeezed them both simultaneously, so she'll get what you mean.

Aria let out a small moan before giving you smile with bedroom eyes, "Alright, it was probably nothing anyway." She then cuddles against you and just that; she was instantly knocked out.

As soon as she was deeply asleep, you looked over to your closet and signaled Sunset that it's safe to come out. She did, but when she did, you noticed the heavy blush on her face, though you didn't ask about it because you can probably guess why. "I owe you and Twilight for that potion," you whispered so you wouldn't wake up Aria.

"You don't need to, and I'm sure Twilight would say the same." Sunset whispered as well, "Just remember not to drink too much at a time."

"Still don't see why, but I'll take your word for it."

"Good. Now that's all is said and done, I'm going to go home and rest. Probably need to take a show first," Sunset said while silently speaking that last sentence. She then left your room. Soon you heard your front door open and closed.

You looked back at your girlfriend while she's still sleeping. Despite her current sex-crazed behavior, you still find her cute sleeping. You then wrapped your arms around her and soon joined her in her slumber. It looks like things are starting to look up.
