Dinner with Dad

I dated a nice man for a month now, Magnus. He's quite a bit older than me but makes me laugh, is handsome, sportive and has a way with me that makes me melt. Our sex has become hotter and crazier by the week and he somehow stretches the limits more and more.
Last night he knew I was having a short dinner with my Dad. We went to a pizzeria around the corner. I dressed in a blue thin dress as Magnus asked and looked forward to catching up with Dad (my parents are divorced so I do not see him very often).
As I was leaving to meet him, Magnus was at my place and he grabbed me and hugged me and kissed me deep. As we french kissed he reached under my dress and pulled off my panties by tearing them at the hips. "I want you to go see your Dad with nothing underneath please".
He smiled that smile that makes me melt and so I took off my bra too and gave it to him. He then turned me and escorted me to the door and as I opened it and was about to step out on the landing he grabbed my neck firmly, bent me over and showed me a but plug. It had 'Slut' written in italics at the top. He had me suck it wet and inserted it in me.
"I want you to wear this as you meet your father."
He then raised me again and quickly put a black satin choker around my neck, with a metal heart-shaped ring in front.
"Keep you mobile nearby, at the table!"
I left, feeling very self conscious.
My Dad hugged me tight as we sat down. He ogled me as we ordered our pizzas, and I felt that the cleavage of my dress was a little too deep. Even the tall Italian waiter looked straight into it as he broughts us our drinks.
Dad and I updated each other on his work and my studies as we ate and drank.
Then my mobile started pinging. I looked and saw Magnus' message:
"Think if sucking a big hard cock!"
He also sent along a closeup picture he had taken of me sucking his cock.
I blushed hard and Dad smiled and asked how my new boyfriend and I got along.
I said that we weren't really yet together but that I really liked Magnus.
I had the mobile with the face downwards when another message came in with a ping.
"I want to cover your face in cum and have you lick it all up!"
The picture was of me with a huge load of sperm on my face, one that another man had taken of me a year back and I knew was circulating on the internet. Gosch, Magnus had found that one.
I finished eating, red in the phase and feeling my nipples stand out under the thin dress. Dad looked at them and smiled. He asked how I was financially and if I needed some money for anything. I answered that I was Ok for now but that contributions were always welcome.
He paid for both of us and we rose to leave and as we hugged goodbye he whispered that I should just let me know if .. as he in return would welcome some help from time to time. He complimented my dress and we parted. He must have meant something else, I told myself as we parted and I walked the short distance back home. As I walked the one flight up to the apartment, Magnus sent me another picture of me naked with just a leather collar and my tits tightly tied up and the text 'Whore Lena' on top.
As I opened the door Magnus stood there waiting. He grabbed me before I could close the door, kissed me and then in one swift move pulled off me dress.
"But please ...!" I gasped, as he pushed me down on all four.
"I want to fuck you so bad, bitch!"
Before I could protest or do anything he had pushed into me from behind, held my hips high and tight and fucked me furiously.
He then pulled out and walked around and kneeled in front of me. He wiped his wet big hard cock over my face and then started mouth fucking me.
"Daddy's little bitch!! he cried out as he climaxed in my mouth.
He held my head until he had drained himself in me and I had swallowed his whole salty thick load.
"Did you have a nice dinner with your horny Dad?" he ssked, holding my hair and slowly wiping his cock over my face.
"Yes, thank you .."I mumbled, feeling very used.
