BF and I have a trip planned to the hills with some friends next week.

The discussion came up about some fun activities in the adult play realm.

One of my GF mentioned that she has a mummy sleeping bag and would love to have us use our human size vac bag on her while she is in the sleeping bag. BF has a full face breathing mask setup so that part shouldn't be a problem however we wanted to know if anyone else has done something like this previously...

Gf is a small (less than five foot) cheer girl friend so flexibility and endurance aren't any concerns.

She has also suggested that my bf and I (or her) should do a dual session in the bags...

Any fun ideas for us?
