We caught our breath for just a second, while we sat on the couch and got a little more comfortable. I idly caressed Jess's breasts, up her collarbone... then down to her flat stomach, and back to her breasts. Jess leaned back and moaned, letting me know just how hot I was making her. Jess pushed me back against the arm of the couch, kissing my neck, down my collarbone, down my chest to my large brown nipples. She began sucking and nibbling on one nipple, while her fingers pinched and pulled on. I removed it till her feet after that she told me to stop, I stopped. She took her panty in one of her feet and told me to lay down on floor. I lied down. She told to open my mouth. I opened it, she put her panty inside my mouth and pulled deep inside by her feet. I tasted her panty and I liked it. After 5 mins she removed panty from my mouth with her feet and put it on my head like hat. She asked me do you like it. I told yes mistress.After that she asked ll you drink my pee. I didn’t replied. Well, I was standing there by holding to a vertical rail. I'm a short girl with 5'2'' height. I can't reach to the top horizontal rail by simply standing there. I'll have to raise a bit and take all my hand's length to the top to reach onto the horizontal rail. So I usually hold the vertical one.Whatever, it was not a comfortable position for no one in the bus. As the push came from the back, the man behind me pushed me further. I could not hold on to the vertical rail any more. Had to move. I could feel my balls start to expand. She saw my eyes get wider and started yelling at me to blow my cum all over the window for her. Then I did just that. I shot stream after stream of sticky cum splashing onto he window separating us. My legs were shaking and I had to put a hand out to hang onto the wall so I wouldn’t fall. My orgasm was much greater that I expected. I think it was because this was so nasty. I looked at my load slowly sliding down the window and was amazed how much there.
