As soon as the store is closed, and the siblings know that they're alone for the evening, they can finally get ready for bed. Unlike others, their presleep routine can get a bit more physical. "FuuuUuck, you feel great tonight, Wise~" Belle moaned out as her brother pumped her up and down his cock, lovingly looking in his eyes as he fucked her like a primal beast. "Did seeing Astra's hot body bursting out of her borrowed PJs get you more excited than usual?~" The captivating songstress was currently snoozing in her room, sleeping away after trying to hide away from paparazzi all day.
"D-Don't be ridiculous, Belle." He stammered back, thankful that their rooms were soundproof, since it was near impossible to quiet themselves when they got into it. The sound of skin slapping together as he held her up, thrusting into her needy pussy as she bounced like a good little slut. Of course, the thought of the idol next door, her body just begging to be played with as she slept so defensively. Though, would he feel worse about taking advantage of that, or because Evelyn would rope him up by his dick if she found out, that was the real question.
"You know she likes you, right? Just another girl that is madly in love with my dense brother, hoping for the day he'll wise up pull her in for a nice, deep, heavy, romantic kiss~" The shit eating grin on her face just grew wider as she leaned in closer to his face, laughing a bit at him being unable to meet her eyes. Though a quick peck on the cheek brought him back into it. "It's a good thing you have your sister here to milk your dick every night to help you sleep, otherwise those poor innocent girls would be subjugated to your perfect bitch breaker. Heh, you can just imagine Zhu Yuan turning redder than a tomato if she ever saw the beast you keep hidden away~" She always knew how to get a laugh out of him, just as she knew the perfect way to get him to cum deep inside of her, emptying his balls in all the right ways.
As the two shared a look that soon turned into a very loving makeout session, they never noticed that their guest was watching from the doorway, giddy as could be. Teasing her nipples as she bit her lip, she was overjoyed to see how close the siblings were, it made her plan so much easier. She had feeling for both of them, and really really wanted to be with them, Evelyn, and maybe cute little Eous. So to see them fucking in front of her, just made her squee inside. It was like watching her own personal concert, imagining herself in between the two as they all made sweet sweet music together. There were two things she knew for certain right now, 1, she was filled with all the confidence, and lust, to write a kickass lovesong!, and 2, she was definitely keeping her new PJs, along with some of Wise's and Belle's underwear, they'd help keep her "inspired" later when she gets home~
Maybe next time she stays over, she can join in on their little "tradition"~
