You'll want to be very careful that they don't get lost if you put them up anywhere but I have a fun idea.

Take turns putting one in your mouth, then one in your ass, then one in your pussy. Keep going in that order until you can't fit more somewhere.

Then depending on what hole was full you'll do the associated task:
Mouth: Eat ALL the grapes you were using
ASS: Remove enough grapes to fit your plug in then plug yourself with the rest remaining.
Pussy:Edge with the grapes still inside. One per grape

Hope you enjoy - and stay safe!
