Wearing panties

After wearing her panties my underwear didn't feel right. Thinking about it for a couple of days I went back to my moms friend house. Her daughter, Terri was home. We played in the backyard for a while before her mom went inside. I finally got the courage to ask Terri. I said, do you have any under pants I can wear. She looked at me and asked, did you wet yourself again. Quickly I said no. I said, I don't feel right wearing my underwear. Terri looked at me for a minute and laughed. You want to wear girls panties, she said. Frightened someone would hear I told her to be quiet.
Embarrassed I was about to leave when Terri said, wait here. She went inside and after what seemed an hour she came back out.
She reached in her pockets and pulled out four pair of panties. I took them and was going to go home when Terri said, I want to watch you do it. I said OK, come to my house.
When we came in, mom was cooking dinner. Terri and I snuck into my room. I pulled off my pants and underwear. I was about to put on a pair of panties when Terri asked can I touch it. Thinking no big deal I said OK. She poked my duck first, then she pressed her hand against it. She laughed and said it feels funny. I said you want to see something funny, watch this. It held my duck and moved my hand up and down quickly. Taking my hand away, we watched it grow. Terri wrapped her fingers around it and moved it up and down. She smiled and said how did you do that. I said, it does it on its own.
I put on her panties and pulled up my pants, and we went out to play.

A few days later after school Terri came over and asked if she could see it again. Mom wasn't home so I said let's go to my room. I said you can see if I can see yours.
We took off our clothes and she pulled my dick till it got stiff. I put my hand on her slit. It felt rubbery. I moved my fingers and slid one in between the lips. We couldn't figure out why we were so different. After a couple of minutes we dressed and went out to play.
