I Masturbated With My Twin Sister

I have a twin sister and we’re both 15 and will be 16 in 3 months. We each have our own bedrooms with a shared Jack-n-Jill bathroom between them. Last week I forgot to lock the door from her room. I was putting my compression shorts and shirt I wore to football practice in our shared hamper in the bathroom before getting into the shower. I saw a pair of her ** on top and grabbed them and took a sniff. At the same time she walked in and saw me. I froze with fear and embarrassment. Told her I was curious and sorry.

She then admitted she sniffed the armpits of my dirty t-shirts, compression shorts, and cup from the hamper. Then she walked over to her door and locked it and went to the hamper and took out the compression shorts I just threw in. She began to sniff them. I put her ** back up to my nose and sniffed. She took her free hand and slid them down the front of her shorts. Next she unzipped her shorts and slid them down along with her **. Then she started Jilling off and kept her nose in my shorts and inhaled hard. I too kept sniffing and started **. I blew my load and soon my sister finished. She looked at me and said clean that up and by the way mom said dinner be ready soon.

Today my parents weren’t getting home until late. I got home from football practice all sweaty. It was really hot out today. She asked if she could smell my cup. I opened my bag and gave it to her. She put it up to her nose and smelled away. She then took off her shorts and ** and handed her ** to me. I smelled them and got a chubby. I was wearing a sleeveless t-shirt, compression shorts, and shorts. She asked if she could sniff my armpits and I agreed. She spent several minutes sniffing and smelling my sweaty pits. She told me to take off my shorts and give her my compressions shorts. I took them off and handed them to her she sniffed them and started jilling off and I’m pretty sure she orgasmed. I was pretty worked up watching her.

She told me I could smell her LuLu. It took me a minute to figure out what she meant. She sat up on the kitchen table and **. I got on my knees and put my nose near her **. As I took in her scent I started ** and ended by blowing my load on leg. I’m feeling very weird about it. I don’t want to ** my sister, but I keep thinking I would do it again with her.
