For a couple years, Clara had been ambivalent to sex... of all the men she's dated, only a few had gotten close to rocking her world. But she'd be blind to not notice the hungry looks from men around her. Even her male friends... 

One night, after letting a friend vent about his string of bad luck with ladies, she felt like doing him a favor and just... letting him fuck out the frustration on her. As expected, she didn't get much out of it, but he was so relieved and grateful! That satiated smile on his face... she got into the habit of helping out her friends whenever they needed the release.

Now, she's got more friends with benefits than without. It makes them happy, and it's no big deal for her, even if it eats into her schedule a bit.

No-dialogue version below. Enjoy!
