Unveiling Secrets: The Transformation of My Bel...

My girlfriend's sister likes me more than I thought...
My girlfriend always had a good relationship with her sister. They did everything together. My girlfriend is 18, about 5 ft, dark hair, chubby at 65kg, and her sister is 14, about 5'1, blonde hair, and skinny at 40kg. Usually, when I'm not there, they'll just sit together and talk, play games, watch TV, either way whatever they were doing they did it together.
I never really mind what we do, so I just do whatever they're doing with them. I am 19M and my girlfriend 18F. Her sister is on the other side of me, about 5ft, 32 inches tall. She has pretty curly hair and blue eyes.
We were hanging out at their house one evening when her sister noticed she was feeling cold. She went up to us and told us we needed to do something to warm her up. Her sister asked me if I would be happy to help her get a bottle of hot cocoa or milk to drink with her. I agreed, so she gave me the task.
I headed into the kitchen and grabbed some milk from the fridge. When I arrived at the door, my girlfriend was already sitting on the couch. She looked up and smiled. "I'll get you there," she said.
When I arrived at the house, it was cold outside. I opened the door to find her sitting on the couch with a bottle of hot cocoa in front of her. She took a sip and started smiling again.
I took the milk from the fridge and went back into the kitchen where we were doing our thing. I grabbed a cup of milk from the fridge, poured it over Faith's head, then let her walk around. Then, I walked over to Faith's little sister and poured hot cocoa over her. I walked up to Faith's little sister and turned her on. We walked back together.
I can't believe how much fun we had tonight. She was so patient and caring with me, it was amazing. I'm looking forward to our next night out!
