One time when i was younger I had morning wood and was trying to pee into the toilet. When you have wood it is kind of hard to pee,so while I was trying to work it out of me,my sister walked in. It probally looked like i was trying to
W***-off into the toilet,but i was simply trying to relieve myself... Anyway,years later our familes went to the beach and while her husband and I changed into our swimming trunks,I couldn't help but catch a glimpse of his man-thing and it looked just like my man-thing,minus the wood thankfully. But if it did (have wood) I believe it would look just like mine,only smaller).
The moral of the story: Little brothers like to smell and toss-off into their older sisters soiled
panties and little sisters want to marry guys with a schlong that resembles their older brothers when they thought they were trying to shoot their load in the toilet (but were just trying to take a piss)!
