You sat in your boosted seat in acting class, listening to the teacher drone on. Your small size usually was pretty useful for acting class, often able to act as a dwarf or hobbit very easily, in comparison to your more normal sized classmates.

You'd grown a fondness for it, having been made to suck womens breasts or able to watch them change clothes having been extremely exciting for the highschool student that you were. The teacher went around, asking what roles everyone would want to play. Once she got to you, you nervously said "...Baby...", and the teacher nodded her head.

Or, if you'd prefer to act out with a real mother, I could ask a friend of mine to help you out with your assignment by acting out a mother.
