Snug

“You can try if you like,” she  said sweetly…
He did, and it fitted quite neatly…
So snugly indeed,
And with which she agreed,
That she said  “Stick it in me completely!”

In the end

Oh, the depths to which some men descend!
She fought hard, the young lass, to defend
Her shy virtue, her honour…
Alas, though, a goner…
He still got it in, in the end.
