SRTS/Have them lick your balls
From Create Your Own Story
You look back and forth between them, then decide to start with the one on the right. You look her in the eyes and say, "Get down on your knees and lick my balls." As you say it, you spread your legs to give her head room.
You are a little surprised to see her go to her knees and immediately use her tongue on your balls. Her sister watches to see how she is doing her task, which you guess is giving her an idea of how to do it better. Her tongue feel incredible as it works both of your balls relentlessly. You grab your other sister's hand and have her start to stroke your cock. With a little assistance, she is working it like a pro.
After a few moments of enjoyment, you have them switch. It does not take long before your sister that was previously stroking your dick to start licking your balls. The other sister is assisted with working your shaft with her hands.
You are close to exploding, so you have them stop. Then say, "Both of you get on your knees and open your mouths. Do not swallow what I put in there. If you swallow, you lose. They both get into position and you start to jerk yourself hard. It only takes a few strokes before you start to fill both their mouths with your cum. There is way too much as they both have some dribble down their faces and onto their tits.
Once you finish you ensure neither swallowed any, the say, "Now kiss each other on the lips with open mouths."
They immediately start to kiss each other, which causes more cum to fall out of their mouths and down onto their tits. After a short time, you say, "That is enough. Now swallow what is in your mouth."
They both swallow your cum. Then you have them use their tongues to clean the cum off of each other.
