Lesbians on the street

I was going to work one morning and crossed an intersection. Then I got the residential buildings next to our office park and had like 5 minutes until I arrive. That was when two gorgeous blonde girls popped up in front of me and asked me the weirdest question I've ever been asked in my life. 

-Hey, um...sorry to bother you but you seem like a nice dude. We are lesbians, and we live together and we want to try something new. We want you to watch as having sex. Do you want to? 

We talked about the details for a bit, then the deal became clear to me: I watch them have sex, but can not touch them, I am just a spectator bringing a little spice into their relatinship. We went up, I got a chair and a cold drink and I settled comfortably. They started undressing each other with love and passion and it made it all the more enjoyable. They got totally naked and their bodies were perfect. After that one of them went down on the others gorgeous sweet pussy. 

After that the two gorgeous and cute lesbians formed a 69 and started licking and fingering each other really hard until both of them screamed with joy and orgasmed right in front of me.

This was the weirdest but most arousing experience of my life.
