Meena giggles as her sister reminds her of the promise they made long ago. However, even as cum leaks from her cock still, she starts thrusting and saying, "Mmm...Of course sis. The biggest harem for our own desires." she purrs out, "But first, let's fill that buttslut craving of yours~" as she pushes her sister against the wall a bit rougher, hands moving away from the cock to grab a tight hold of her sister's ass and her movements became a lot smoother, a lot more sure, and a lot more lustful. Her hips speed up and becomes more forceful as her cock roughly takes advantage of her sister's eager, cum lubed tailhole. "God! I probably never would have to bother with more bimbofication experiments~ I doubt you could become more of a whore for me, sis~!" she moans out. She never intended the Temp-Bimbo thing to be used on her sister, but the fact it had some lasting effects is something she didn't mind. It was a med to enhance a couple's desire in the bedroom if it is refined well enough, and it's proven very nice at making her sister and herself a lot, lot more closer~ Though, she did get the fun idea of getting one of the refined doses and using it on her sister again. She did enjoy her sister being practically glued to her cock, obedient, and unquestioning for a while~
