Adult women (middle-aged) giving each other piggyback rides

No

Are you the "sleeping on the shoulders" person?

Birdyback rides!

were you both naked

I don't see why not. Piggy back rides can be fun at any age. :D Oh, and by the way, me and my friends give each other rides in the wheelbarrow and were in our 20's.

Just make sure your friend shouts "EAGLE" while being piggybacked.
