Read it.

When I opened a new message from an unknown number I got a bit surprised. It was from a math colleague and he sent me an image of what appeared to be his muscles. And he even wrote:

• "Up for some fun babe?" I wasn't sure what to do with it. I certainly didn't ask him for any photos. And certainly, I didn't give him my number.
• "What do you want Matty? Where did you get my number?"
• "That is not important Lucy, what's important is that I am horny and you have a great piece of ass."
• "What exactly do you want? I am losing my patience here."
• "Well, how about a little game called I showed you mine now you show me yours?"

Was he insane? Was he really expecting me to follow along? Then again, what if I did? His muscles were very tempting, to be honest, maybe I could get more... On the other hand, wasn't that cheating?
