When my little sister was about e****n years old she started having her periods. She had cramps, she had an upset tummy, and she ran fevers…every twenty-eight days…just like clockwork.

She got to miss a lot of school because of it too.

Then just after she turned thirteen she came into my bedroom and said, “Twist my nipples just as hard as you can. Mom said that you had too.”

Well fuck that shit. I wasn’t about to fall for that. I just got off being grounded and I wasn’t about to go right back on.

I ran down the stairs, found Mom in the kitchen, and told her what my sister had said.

Mom laughed and said, “You turned her down! You of all people! I thought that you would jump at the chance.”

Savannah came into the kitchen just then and screamed, “He wouldn’t do it!”

Mom said, “Okay you two, settle down. Now your sister has had a very hard time with her periods and they are getting worse every month. So I told her what I used to do, at least when your father was still living here.”

He would twist my nipples very hard and that would cause my period to start to flow and then after that I always felt better.”

I turned to my sister and said, “Okay, pull your shirt up.”

Savannah got white as a ghost.

Mom said, “That was what I had to do with your father.”

Savannah said, “But that was your own husband. He’s my brother.”

Mom said, “Then don’t do it. I don’t care one way or the other.”

She reluctantly lifted her yellow T-shirt up under her armpits and stood there. As I approached her she closed her eyes and turned her head.

Mom giggled and said, “Now get a really good grip on her nipples, don’t be afraid to get some tittie flesh in there too, then pinch and twist just as hard as you can. Don’t stop until I tell you too.”

I looked at my sister’s breasts. They were round and firm with nice nipples and hardly any areolas around them. It was my first look at a girl’s chest. I reached to touch her nipples and she cringed and started to pull away. With Mom’s encouragement she stood still for me. Her nipples hardened for me. I reached out and held them gently between my fingers and then all of a sudden I clamped down on them hard and then I started to twist them in opposite directions. She cried out in pain and Mom eventually told me to stop.

By then Savannah was on her knees crying her heart out. She could hardly catch her breath let alone say anything.

The first words out of her mouth were, “That fucking hurt! It was the most pain that I have been in, and I fell off the stage last year during rehearsal for Little Abner.”

Mom said, “In a few minutes that pain will go away and so will your cramps. I promise.”
