March In Like a Lion

[sirhugs]

I'm not a big mom/son incest fan, but this idea works best for that:

A young school teacher trying to liven up the science lessons decides to present a skit about climate based on the saying "March in like a lion, Out like a lamb..."

He askes his Mom to help him with a costume. In the course of the fitting, something grows to leonine proportions. Mom finally says "We can't fit this costume with that thing all swollen..."

I suppose you could do as gf or wife helping, but you lose the taboo aspect. Similarly, teacher could be middle aged Dad, widower or divorced, with daughter helping.

Or daughter as teacher & Dad helping?

Maybe Dad is gay, came out of the closet years ago, but has this strange reaction as he fits the fabric over daughter's breasts? his line would be "We can't fit it with those nipples so hard..."

and then there's the music teacher who dresses as a lamb...

The saying could apply to the pre-sex and post-sex male member. It goes in like a lion (large, proud, and roaring) and comes out like a lamb (small, soft, and shrunken).
