caught up

so i was babysitting this little guy for a friend and we started playing a game where he calls me mommy and i do all the grownup stuff like making him take a nap even though hes way too old but it got kinda intense when he asked me to read him a bedtime story in my voice which made him really squirm with laughter and i ended up spanking his little bottom to keep things in order it was so unexpected and naughty at the same time im not sure if its normal to get turned on by this kind of play
