I took the car down to Professorstaden and parked it outside Katrin’s house. As I went up to the house, the door opened and out stepped Julia. She looked at me without a hint of surprise. She closed the door behind her and walked up to me.
“So. It’s you,” she said crossing her arms over her chest.
I raised my eyebrows.
“She’s waiting for you inside. I want a free lesson when I’m back at elven. Bye,” she said walking past me and up the road towards the university.
I stood there for a second looking at the young woman as she walked away from me. Then I shook my head and took a deep breath. Walked up to the door and opened it. Katrin was on her knees wearing her bathrobe. She was looking up at me pleadingly. I looked over my shoulder. Julia had just disappeared behind a corner.
*Interesting*.
I closed the door behind me and looked down at Katrin.
“Take your robe off.”
She did as she was told. She wore nothing underneath. I reached down and grabbed one of her tits and squeezed it hard. She winced and bit her lip. Her nipples became stiff like two ripe raspberries. I pinched one of them. Katrin winced again.
