He pushed my panties aside and I felt something rock hard, warm, and wet pressing against my butthole. I got scared, thinking his thick penis would hu...t me so much and then I tried to resist that anal invasion. But he held me in position and told me to relax.Then I felt his cock penetrating my tight asshole as he pushed the tip in. It stretched my butt open and hurt. I though he was going to split me in two.He pushed more and more very slowly. I could feel his breathe in my neck as he invaded. He was feeling sadistic. I couldn't hear a sound. I couldn't feel the heat of his body and the anticipation was almost too much.I felt a something sharp and cool caress my backside. I shuddered with fear as the object drew patterns into my skin. There was no pain, but not knowing what this was or what he was doing heightened my senses like never before. I could feel his hand begin stroking my back as I trembled beneath him. The sensation stopped and a new one started. Hot and wet- his tongue. Turning into the drinks aisle with my half full shopping trolley I spotted my bosses wife, Liz, walking slowly down the aisle eyeing the various bottles of booze on the shelves.I had meet Liz a couple of times at works functions when she had seemed a bit snotty to the rest of us on her husband Tim's team.

"All you have to do is sign up with us and carry that card with you.If we get enough people on board we can stop animals being used in research.All.
