You seen mine, now I get to see yours.

After a few minutes more of letting her masturbate you, you ask her "So you have seen mine and hell even touched it too. Can I see yours?". She stops masturbating you and pulls her hand away in shock. "Wait, what? We can't be doing this John" she says while looking wide eye at you. You smile big at your sister and say "Well it is only fair sis. You saw my cock and even played with it some too. Plus I could show dad that video".

Your sister looks defeated and slowly uncovers herself but keeps herself balled up. "Come on sis. I can see plenty of your skin by looking at your own arm. Open and show your flower" you say while pulling at her leg. She slaps your hand away and slowly opens her legs and pulls her hands away so that you can see her body. You notice she is very wet. Oh look she shaves down there. This will be good.

You kneel down to get a closer look and she balls back up and backs away a little. "Come on sis You got this. I have already seen it. All there is to do is for me to touch and masturbate you a little. You know it will feel good" you say with a grin. She starts to spread back and when you reach in and touch the lips of her pussy. She flinches a little and moans too.

You rub your finger up her slit and flick her clit some and she moans even more. You bend down even more and place your tongue at the entrance and flick your tongue up a little and she bucks a little and pushes her pussy into your face.
