i was 8 and my little sister was 5. we often bathed together and would wash each others body in the water and play games. when my parents left us alone in there we played our special games like touch- tickle- lick where we would take turns pointing to a special body part on mine or her body then touch tickle and lick it (i picked her nipples everytime to start with because she told me she loved it so much). I taught her how to play willy wanker, and showed her how to make my willy go from soft to big and hard, she really loved playing that and so did i! she didnt like the taste of my spunk, but she loved to watch it squirt out of my penis right up until i was 25 haha.
