Yes

So you two head back to your house. "Now let's see this dildo." She barely makes in the door when she unboxed it. "It's so big! Bro can you let me have some alone time with this well. Im gonna name him sticky. Sticky the dildo. Well I'm gonna go have some fun." She runs away with excitement.

Later on I decide to check on her. To my surprise her and mom are using a double sided dildo.

You will now take to view of sis for this flash back: This dildo is great. I could use this all night. Oh crap mom's about to come in. The door cracks open. I throw all of the sex toys under my bed and cover up. "Hey little girl. I want to tell you something if you have some time. Yeah okay so I know you and you brother are really getting along but I was wondering if you have any questions. Like lady question your brother wouldn't get?" I looks at her and catch my breath. "Well actually yeah. That is luck you asked. You see well my boobies are really small. Their not big like yours. Why is that?" Mom looks at me and says "one day your titties will be big just like mine. When your older. If your boobies don't grow in then that's okay and it's just how God made you. What else?" Hopefully my boobs do grow in. It's kinda embarrassing in front of bro. "So I'm really short. I have to shop in the kids clothes. Do you think I'm pretty?" "Yes I do baby girl." I look at her huge breast. "Before you came in I was using some new dildos my brother bought for me. Could you help me use them?" She uncovers me and says "yes"

Now we are back in the present under our protagonist view: wow they are so pretty. I don't think I should disturb them. I walk away and go to sleep.
