I guess I should explain that I am a middle aged gal (38) and not into deliberate panty pooping - although the following was quite an experience - embarressing, but also a relief and a bit naughty.
To make a long story as short as possible, I periodically experience constipation (hadn't gone this time for about three days) and was unconfortable to say the least. So I used two Ducolax suppositories and lay down on the bed with only my top and panties on to relax until they started to work. I find they usually kick in, in about 30 to 40 minutes when its been awhile. The adventure began when I drifted off to sleep and dreamed that I was walking through a woods and needed to move my bowels pretty badly. Seeing no one around I pulled my panties down and let Mother Nature take over. The difference was of course that in reality I was laying on my stomach with my panties still on when I relieved myself. I guess I was still in a dreamy state as I grunted with the explusion of several really large logs in my panties - just as my husband walked into the bedroom. Talk about embarressing! My husband just grinned and asked if I felt better. At first I was at a loss for words but managed to remark that at least it was relaxing. He helped me up and into the bathroom during which I noticed he was obviously enjoying the situation. We then relieved each other in the shower of another kind of pressure. I should admit I've had a few more accidents since which have spiced things up a quite a bit.
