Claire. Of course.

You pick up your phone.

Claire. Of course.

The message is short. "Doggy, Missionary or Cowgirl? Gonna be your choice! Lol!"

Your mouth goes dry. It hadn't occurred to you that Jennifer would get adventurous with positions, but jeez it's just the kind of thing she would do! You can feel your face burning and you're glad Claire isn't there to see her words, as always, hit home.

Your phone buzzes again. This time its a picture message. A close up of the unopened strap on box, which shows a proud blonde woman, hands on hips, with the purple, ribbed dildo jutting out threateningly. It's called a Purple Avenger - "8 inches of fun" the box brags.

You remember the first time Claire proposed this. It was a couple of days after you had given her a sound anal pounding, making her squeal. You'd teased her about it afterwards and she'd clearly felt some need to even the balance.

No way, though, you'd said. No way!

Claire's caption reads "Don't pretend you don't want it! Xxxx"

Your heart sinks. This is going to be shameful. And the worst thing is that Claire is right - it's also strangely exciting.

You hear the tap stop downstairs. Man, that Jennifer. She's going to lord it over you after this. And the worst thing is that you know she has been cheating.... if only you could prove it....
