Secretly Sucking On Puffy Nipples

This happened a while ago.

I went out with my best friend. We went to a club and danced, drank and laughed and had the best times. We dressed sexy that evening. My friend especially was dressed so hot: so was wearing a dress without a bra, and the dress showed more than just cleavage: you could see the parts of her ****.
I always loved her ****, but never touched them. She has the hotttest puffy nipples you can imagine: soft pink areolas with great nipples on top. I think it's a c-cup. She has a beautiful curvy tanned body.
Because her dress was so open, you could sometimes see a part of her nipple when she was dancing. I loved it, together with all the male guests in the club.

We drank a little bit too much went home with a taxi. Sitting in the taxi I noticed how drunk she was. She wasn't aware what she was saying or doing. One of her **** almost fell out of the dress but she didn't noticed. I tried to adjust her dress but she pushed my hands away and made it worse. The other boob was visible too and half her nipple showed.
I saw the taxidriver checking her in his rear view mirror.

When we arrived at her place I decided to help her get into her house. She wasn't looking very good and mumbled that she felt sick. In her bathroom she had threw up a couple of cocktails. But instead of throwing up in the toilet, it was all over her body. Luckily we didn't eat much so it was all alcohol.

I couldn't leave her like that and took her clothes off. She was almost sleeping. When she was sitting in her shower, naked, I got kind of warm. Of course she didn't smell very good, but the idea of her not knowing what I was doing to her, combined with the sight on her lucious **** made me feeling nervous and excited. I washed her as good as I could. I was so good to feel her skin, but holding her **** in my hand made me wet. I touched her breast, her nipple, squeezed and pinched it and it felt exactly like how I expected it. Her eyes were closed. I looked at her ***** and I was surprised about the size of her ****. I touched it really gently while washing her.

I woke her up a bit, to get her out of the shower. I wrapped a towel around her and helped her towards her bed. She sat down and immediately fell asleep again, sitting against the wall. I was happy to see she had a bit more colour in her face. I took away the towel and took a blanket to cover her. To cover her naked body, but not entirely. Her boobs stayed uncovered.

I got tired and decided to spend the night at her place. We did that often and i knew she wouldn't mind. I was laying next to her and staring at her ****. Her nipples were even more swollen because of the warm shower. I opened my mouth and before I knew what I was doing, I touched her nipple with my lips. Very gentle I started sucking on her nipple. Not only the nipple but half her *** was in my mouth. I was such a great feeling and turn on. I started playing with my ***** and rubbing my ****. The whole time the *** was in my mouth. I couldn't stop and sucked harder and harder.
She was still sleeping. I just took me a few minutes to come. After that I fell asleep with the nipple in my mouth.

The next day we both had a hangover, but hers was huge. She couldn't remember anything about the night before.
I told her what happened a week later, and confessed about sucking her ****. She was quit and then started laughing, actually it was a big turn on for her. And she asked me to do it again, but then while her boyfriend could watch.
