"Andy!! I'm so happy to see you! Please come on back" said Carlos with his signature smile.

"How are you feeling my love? Any improvement in your back?"

"Hi Carlos. Thank you. I'm good. Feeling much better today" I said as I followed him to the room. I wasn't feeling as nervous. I was shy, but decided to flirt back.

"I'm very happy to hear that. Let me get your medicine from the fridge. Lower your pants and get comfortable I'll be right back"

This time I lowered my pants more. Uncovering my full round bottom and the underwear was halfway pushed to the middle of my butt. I leaned forward and waited for him.

The door opened. "My god what a sight! I'm going to have so much fun with you Andy"

"If you're as good as yesterday I'll be happy to come get all my shots from you"

"Oh you have nothing to worry about young lady. My hands will be all over your butt very soon"

"We'll see. I might change my mind and find someone else" I said playfully

"You should be careful what you say when I have a big syringe in my hand" Carlos said as he started disinfecting my left buttock.

Today he only needed to give me the muscle relaxant. My butt was s little sensitive from having 2 other pokes in it but I wasn't worried. He took his time disinfecting. It felt like he was swabbing my entire cheek with alcohol. I was already so turned on. Hopefully he wouldn't notice.

"Here it comes Andy. Be a good girl for me and don't clench" he said as he stuck the needle before I could say anything. I definitely felt it, as I could feel my wetness in my waxed pussy.

"You really have such a gift Carlos. I could barely feel it"

"I told you, I would never hurt such a beautiful young lady. Such a shame I only get to do this 4 more times. I'll have to find excuses to keep seeing your butt"

"Well enjoy it while it lasts" I said as I felt him withdraw the needle and put pressure.

I put my pants up and turned around and found him looking at me, smiling. He approached me and pushed me with my back towards the table and started kissing me. I reciprocated. His lips felt so soft and I felt shock waves all over my body.

"You really are beautiful Andy" he said with his hand on my face.

"You're very handsome and sweet yourself Carlos. I'm very glad you're the one doing this"

"Take care Andy. What time tomorrow?"

"After 3rd period. See you Carlos"
