As a couple we've been together over 2 years and have been experimenting with inviting another for threesomes for just over a year now... When lockdown hit, we were trying to think of new ways to still play with others safely and thought of a glory hole at home... We erected a basic one to try out at home for just us two with shower pole and bed sheet with a hole and my partner REALLY enjoyed using it. Now considering a more robust solution for the future!
