A double - When two girls use two dildos at the same time, one in each

When two girls use two dildos at the same time, one in each hole. It’s messy, it’s loud, and it’s the best thing ever.

My friend and I did a double double, and it was loud, messy, and amazing.

I asked my sister if she wanted to do a double double, and she said, 'Yes, and I’m bringing lube.'

My boyfriend said, 'You guys are doing a double double?' I said, 'Yes, and it’s the best thing ever.'
