For a moment i was still with shock. I had reached for the pen. But she had picked it up before me. As i lifted my head, my lips had accidentally brushed the bare skin of her ass. I immediate pulled away, but she pushed back against my lips, which again were touching her skin. I unfroze and realized that the skin that my lips were touching was not her ass. She was wearign a garterbelt, but nothign else under her skirt. I was kissing her sexual lips. My lips suddenly became wet.
