An opportunity arose this morning which I couldn't resist.
It was my sister-in-law's birthday today and my wife and I were going to walk over to her house to drop off the card and presents. On the way back, my wife was going to catch the bus to the hairdresser's, and I would walk home.
I decided to wear a pair of my wife's silky black knickers with the intention of filling them as we walked back. Everything went beautifully to plan, and I was quite turned on, sitting in my sister-in-law's house knowing I was wearing a pair of ladies panties. I was getting a bit desperate to poo and the women were still yakking, but eventually we rose to leave and I clenched my buttocks to prevent a premature evacuation.
Strolling down the lane, chatting to my wife, I relaxed and allowed nature to take its course. It didn't take long before I felt my poo ease out between my buttocks. I allowed the warm poo to just touch my knickers and then drew it back in again so as to repeat the process. What a lovely tease that is! Eventually I could wait no longer, so I gave a deliberate push and had the enormous adrenalin rush of feeling the entire load of poo spread out into my knickers. What a sensation! My jeans held the load tightly, so my poo oozed between my legs and I could feel the warmth spreading around my balls. A tentative feel around my bum confirmed my suspicions - a very nice firm bulge indeed. Soon we reached the bus stop and I waited with her until the bus came, taking great care to stand downwind of course.
The icing on the cake arrived as we were waiting for her bus. I was of course extremely horny, so I casually stood with my hand in my jeans pocket and squeezed my swollen penis. The bus came, I gave her a nice kiss on the lips, and then I came with such a forceful ejaculation I felt sure she would notice. But no, off she went to the hairdresser's without a care in the world.
It was only a few hundred yards to walk home but I thoroughly enjoyed every step of the way, with that lovely warm load nestling in those beautiful black panties. Once home I quickly stripped off and examined the damage. Luckily the jeans had survived with only the slightest mark, but the black silky knickers were bulging ominously. I stood in front of the full-length mirror, held the bulge with one hand, and gave myself another thorough masturbation. What bliss!
