Claire tells Samantha all about your night together

It's immediately clear the next day at work that Samantha has already been briefed. She can't keep a straight face when you see each other.

"So someone had a good time last night, I heard," she says teasing you.

"Hey, I wasn't the only one. She had a good time too," you say smiling back at Samantha.

"So, I heard," Samantha says and you wonder just what details she did hear. Did she hear about the size of your cock - she her sister mention how good you are at eating pussy. Does Samantha know that her little sister swallowed two of your cum loads?

"Don't you have a girlfriend though? What about Emma?"

"We have an agreement. It's all on the up and up," you lie.

"Good, don't drag my sister into your nefarious deeds!" Samantha says and walks away.

It seems the two sisters continued to communicate, because later in the day while you're working in your office you get a text from Claire asking if you had told your girlfriend about last night.

"We don't share the details," you respond and then Claire asks when you can get together again.

"Next Thursday?" you offer. Claire responds that that's a really long ways away and that she already misses your huge cock.
