I slept like a baby after a very steamy session with my fingers thinking about what happened earlier. I woke up feeling refreshed and almost pain free. I was definitely looking forward to seeing Carlos again. That kiss was magical.

The weather was beautiful today. I decided to wear a skirt and a blouse to spice things up. Also wore a thong under my skirt. Was looking forward to seeing his reaction. Carlos was very sweet and gentle. He was definitely my type. Maybe today I wouldn't close my eyes and I'd be able to see his erection under his gray scrubs.

The classes felt eternal. I was definitely ready for them to be over. As soon as third period ended I rushed to the health center. I always hated how far away it was located all the way on the other end of campus, but I didn't mind I was excited to see Carlos.

As soon as I got to the health center I saw a girl wearing scrubs in the front desk. I panicked. Was Carlos not there? I definitely didn't want anyone else seeing me. Especially since I was wearing a sexy thong. I debated what to do and then I heard my phone beep with a text message notification. "Andy I'm busy with another student please give me a few minutes. Don't go with anyone else. I can't wait to see you" phew I'll wait as long as it takes. I went to the campus cafe nearby and got myself a coffee. I'm glad he looked up my phone number in the school system, and I'm even happier to have his.

After half an hour I get another notification "please come on over I'm ready for you and I asked my fellow medic to give us some privacy". My heart started racing. I picked up my backpack and went back to the health center. He was there by the front desk wearing his signature gray scrubs and s big erection under them.

I walked in and gave him a big hug and a quick kiss on his lips. "I'm so glad you're here and you texted me. I was so worried"

"Please save my number sweetheart. I'm glad you're here too. Come on in and follow me"

I got to the room and he asked me to sit on the table as we talked for a minute.

"Andy, you're a really good patient. These shots don't really hurt but I want to see if you can handle a little bit more. What do you say we spice things up and add some vitamins too?"

I was shocked at the proposition and didn't know what to say.

"I looked in the system and you're taking way too many classes. No wonder your back gave in. I want to give you some vitamin B12. I think it will be great for your immune system. What do you say?"

"Ehm yeah um I guess. Ok" I said nervously. I had gotten so comfortable with these shots and now I was anxious again.

"That's my girl. Ok stay put while I get them from the fridge. Feel free to get comfortable. I'll be back"

I leaned over the table and put my skirt all the way up. I kept my thong hoping it wouldn't be on the way. Also wanted him to see it as I picked it just for him.

"Wow Andy you're delicious. What a beautiful behind you have back there. And I love the thong. Great taste"

"Thank you. I picked it for you. When I thought you were just going to give me the muscle relaxant. Now I'm nervous"

"You don't have to be, princess. I will never hurt you too much. We will make it fun. Besides, I can tell you're enjoying getting shots as much as I'm enjoying giving them to you"

I gasped and blushed. How could he tell? Was it really that obvious? What have I done?

"Ugh you weren't supposed to know that"

"Aww love don't worry I am here to help you enjoy it and we're going to have fun together. Do you trust me?"

"Yes. I trust you"

"Very well. I want you to lean forward on the table and relax. I'm going to give you the muscle relaxant first which as you know won't hurt you"

I leaned forward and breathed deeply as I smelled the alcohol and felt him swabbing both cheeks.

I felt him coming behind me very close and kissing my ear. "Relax sweetheart" he whispered in my ear as I felt the needle on my right cheek. I had chills and goosebumps all over my body.

The medication didn't hurt. Just when I thought he was ready to withdraw the needle I felt him near my ear again "you look so sexy with a syringe in your butt. How about we make it 2?" And before I could answer I felt the needle on my left cheek piercing very deeply.

"Beautiful. Just breathe. This vitamin will sting more. You got this"

I felt the sting of the vitamin. I was very turned on. I could feel the needles stuck in both of my cheeks.

"Great job. You're amazing. What a wonderful patient"

He finished pushing the medication and started rubbing my back for a few seconds before he withdrew the needles.

I turned around and we started kissing again. His erection was pushing his scrubs and I was very turned on. The kiss lasted for a very long time and I enjoyed every second. I loved the feeling of his tongue and his soft lips. He was grabbing my bare butt under my skirt and feeling my thong. His hands also touching my hard breasts with swollen nipples. I wanted to stay like this forever.

"What time tomorrow? It's Saturday and you don't have class so we have time to play more. Plus I'll be alone at the health center and we will have more privacy"

"Uh I can be here at 10am. Is that ok?"

"Of course sweetheart. And brace yourself, things are going to get steamier and more fun. But I'm sure you'll be such a good girl"
