One beautiful day in Cloudsdale, I was speaking to my sister at dinner. I said, "Hey Cloudchaser, you think you could get me some more milk?" "Sure, sis." my sister replied, walking over to the fridge to get me a glass of milk. After she brought the milk back to me, I said, "Well, sis, after I drink this I'm going to go to sleep." "Okay," she said, "just don't start sleepwalking into my bedroom again when you fall asleep." "Whatever." I replied. I finished my milk, little by little, and quietly shouted, "Good night, guys!"
When I woke up at midnight to get a snack and a glass of water, I heard what sounded like my sister moaning. So I went to her bedroom door, and asked if she was okay. "Yes! Now get out and go back to bed!" she yelled. So I went back to my bedroom, ate my snack, and fell asleep. I started sleepwalking about thirty minutes later, and apparently opened my sister's door. She screamed, and I woke up only to find her using a toy on herself. I yelled, and out of surprise I said, "Sis, what the hell are you doing?!" She did not reply at all. All she said was, "Do you want to join?" I replied with, "I guess. As long as we keep this a secret." She started to lick my cunt, as if she were waiting to do this for a while. "Wow, you taste very good." she said, filled with awe.
"Thanks," I replied, "let me taste yours!" She then flipped over tummy-side up, and I started licking her. She moaned, with each one getting louder and louder. She stuck her hoof in her mouth, and said, "Are you a fillyfooler?" "Yes, I am very much a fillyfooler." I replied. After 5 minutes of licking my beautiful sister's cunt, I grabbed the toy that she was using. "Oh yeah!" I said, filled with something I've never felt before. I went in and out with the dildo, and started again after she came. She came at least 3 times before she started to use the toy on me. "I've actually never came before," I said, "none of the ponies I dated never really knew how to make another pony cum." "Oh, don't worry, I can make it happen." My sister said, filled with surprise. She put it in, and started making forward and backward movements with the 16-inch toy. I finally came after about 20 minutes, with CC worn out. "I think I should go back to bed," I said, "I'm really tired after all of those movements." "Same here. Good night, sis." I blew a kiss at her, and said, "Good night, hot stuff."
I woke up the next morning, still concerned about why I wanted to join CC. Cloudchaser then got me thinking when she wrapped her tail around mine, and my wing stiffened so much, it started to hurt. "Honey, why is your wing up?" Mom asked me, wondering if something went on last night. "I don't know, honestly. It just pops up at random." I said, trying my best to get it down, while also unwrapping my tail from CC's.
That next night, I figured out why I loved my sister so much. I loved her. Not in a family way, but as if we were dating. So that same, dark night, I went to my sister's room and opened the door, only to find that she was doing it again. "CC," I said, "I think it's time we need to talk." "About what?" my sister asked. "About all of," I stuttered, "this."
As we had our discussion, I finally said, "Will you go out with me, but keep it a secret?" She smiled and said, "Yes, I will go out with you, little sis."
