Texting with Athena

Carrie texts Athena your number the same evening, after that, both of you quickly fall asleep. As you wake up, your girlfriend is still sleeping. You get your phone and get out of bed to shower.
Your phone notifies you of a couple of texts from a new number.

-Hey its Athena. Carrie texted me your number yesterday. Wanna work out? I´m free tomorrow.

-Sure

You think for a moment, then you add:

-But how do I know I´m really texting Athena?

She doesnt respond for a couple of seconds, but then a picture appears. it shows Athena, in front of the mirror in the gym. She wears a white sports bra, pushing up her breasts and loose grey sweatpants. The picture alone makes your dick push a bit harder against its pants.

-Convinced?

_-Sure

-How do I know it´s really you though?_

You smile. Quickly, you get out of your shirt. You slept in some comfortable sweatbants, through which the outline of your dick is visible if you look at it.
You lift the phone abit, and take a picture. The bathroom lights put emphasis on your muscles. Satisfied, you sent the picture. Again, a couple of moments pass and you´re scared that she wont respond, but then a new text from Athena appears.

_- :)

-tomorrow at 8?

-bet._

You smile, and get under the shower. As you come back into the bedroom, Carrie is still asleep.
