Dave, on his sister Lauren

Dave was pretty excited. He had seen an Ad a few days back which advertised a futuristic masturbation lotion. The special twist on this one was not heating lube or something like that, but full-on autonomous masturbation. You could be bound and still feel like somebody is pleasuring you.

Now the lotion is in your hands because you ordered right away. You tested it the night before and it felt really amazing. Now was the time to share the lotion. The future is now old man after all.

You sneak through the house and check the rooms for your sibling and parents. You hear the shower running and by the clothing items on the floor, it's your younger sister Lauren. Lauren was really nothing special. She was kind of the wallflower of the family. She hasn't even had a boyfriend yet. At least not one she actually showed up with at home.

You quickly enter her room and with the lotion in your pocket start searching for her dildo stash. After a short little while, you find a small pink vibrator and a flesh dildo. You generously apply the lotion to both toys and put them back.

Just in time as it seems. As you leave her room you hear the shower gets turned off and your sister humming while she dries herself off. You hide in your room but listen to her movements. After a few minutes, you hear her walk to her room and shut the door.

You enter the hallway and walk over to her room. It's Monday morning before school and you should get ready but you want to perv on your sister for a little longer.

Your sister is suspiciously quiet but when you are just about to turn around and walk back to your room you hear a quiet moan.

"Is she really already using her toys? Maybe she is just rubbing herself without a toy", you think to yourself.

You were about finished with that thought when a loud groan reached your ears. No doubt it came from Lauren. This must be the beginning of the lotion taking effect.

"She is actually using one of her toys!" You can't believe your luck.

You hear Lauren say "What the fuck? Aaah Aaah" and after that, she falls in a steady rhythm of moans.

After she clearly and quite audibly came she was quiet. You hear her move around in her room, steps from one side of the room to the other than back. Then you hear a moan and a loud crashing noise. Has she fallen? You knock on her door and ask if everything is ok. You only get moans as answers.

"Lauren I'm worried! I'm coming in!", you say as you enter her room.

You hear her shriek "NO!" but it's already too late. You see your naked sister laying on the floor moaning and sweating profusely.

"What is happening Lauren", you ask in played concern.

"Aahh! I don't know! My legs don't work properly and my body feels funny." she retorts.

She groans and moans as she tried to cover her lady parts from your eyes.

"Sis, I'll carry you to the bed and I'll talk to mom that you should not go to school today"

You pick her up with your strong arms and walk over to her bed. There is a small wet spot on the sheets where her hip goes which made you smile.

You throw her blanked over her naked body and exit her room. She's still moaning and thrashing in her bed.
