Rin POV
Rin was in her bed trying to fall for some odd reason she couldn't get her twin brother, Len, off her mind. Finally Rin gave up and walked over to her brothers bed. For a moment she just stood next to his bed and watched him sleep peacefully. After a little while she slowly crawled into bed with him and began hugging his back.
Lens POV
Len couldn't sleep when he saw his sister get up from her bed and walk over to him. He was tempted to pull her down next to him. Len couldn't help himself and slowly felt an erection coming on as he looked at his sister with her skimpy pajamas. She was wearing a really short belly shirt which showed her B-cup boobs perfectly and some really shorts shorts that hugged her hips nicely. Len sat there daydreaming for a few minutes without realizing his sister crawled into bed with him until he felt a pair of arms hug his back.
Rins POV
Rin felt so comfortable that she was surprised. Rins mom and dad had told her that it was bad for siblings their age to sleep together when they were ten. Rin didn't understand what they meant at that age but now Rin and Len are 15 and she knows what they mean. But of course they weren't going to do anything. After all love of that kind is forbidden between siblings. After thinking for a little bit longer Rin finally fell asleep.
This is my very first fanfiction so please go easy on me. I know it probably bad and all but please give me some suggestions.
