Jeff could feel sarah picking up lisa and setting her into what felt like her high chair.
"time for dinner lisa, how about peas and carrots?"
Jeff could hear lisas excited babbling as sarah fed her what he assumed was peas and carrots baby food. All Jeff could think was what happens after a baby eats...
After lisa had finished eating, sarah placed her down in her playpen to work off her dinner.
Jeff could feel lisa moving, his face being right in her ass and genitals. It was very uncomfortable for him, but she was none the wiser. after about 45 minutes of this his fears were confirmed as he heard, and more importantly smelled, lisa first... special hello...
Lisa had started to fart, right into jeffs face, and jeff could only hope that it was all she would do. but soon after, she started pushing a little harder and a little wet turd squashed right over jeffs nose and mouth, coating what would be his tongue in the wet feces. to say it was the worst tasting substance ever would be the biggest of understatements ever! and it didn't end there, lisa kept pushing and pushing, forcing more and more into jeffs face. it seemed she had diarrhea or something, most likely due to the wet baby food lisa had been eating...
it wasn't until 30 minutes later that sarah checked lisas diaper.
"wow, you are one stinky baby lisa. I almost feel bad for you jeff."
Jeff suddenly saw some light as sarah removed him from lisas butt.
"well, its not like you are of any use to me jeff, it was nice knowing you"
Then all he saw was the inside of the dirty diaper bin as his former sister just threw him away like, well, a dirty diaper.
