Here’s the prompt!

Pippa and Caltur have been dating for about a year and a half. They’re renting an apartment together, and they’re happy together. He’s invited her into his group of friends, the closest of whom she’s closest with being Pierce. He’s a bit nerdy, kind of an emo, but sweet. He also has quite a dirty mind. Caltur is brave, loyal, and absolutely caring and devoted to Pippa. In fact… He knows he wants to marry her someday.

The two have had sex before. This is no dirty secret or anything.

But there’s something strange going on, and Caltur intends to find out what it is. Every month Pippa makes up some excuse to disappear for a few days. Whether it’s visiting family, something for business, or staying with a friend in another city- For roughly three days a month she disappears. Caltur didn’t think much of it at first until he realized the pattern. In the days coming to when Pippa usually comes up with her excuse he gets Pierce to join him in trying to figure out what it is she does. He takes him back to the apartment so they can talk over coffee about it.

Little does he know, Pippa is hiding her heat from him. She gets embarrassed, and she thinks that he would think she was disgusting if he knew how lewd/honey she became for those few days of ovulation.

Anyways, Caltur and Pierce head in, and Caltur can smell something is wrong. They’re not alone. He calls out for Pippa… Nothing. But he can smell something. It smells like her. So why isn’t she answering?

Her heat came on early, and she didn’t have time to get out of the house before Caltur came home. She’s now quivering in the closet, afraid of being caught and yet still soaked through her panties, trying not to let out a needy whimper that would let them know where she is ;)

I’m thinking he would find her and try to comfort her into telling him what was wrong and what she was hiding from, until he realizes that she’s trying to find on his lap and the smell of her sex is strong in the air… The two have discussed being open to a threesome before. Pierce is there, and they both trust him… So why not invite him to join the fun and satisfy the needy kitty?

Please, please, please be somewhat detailed!
