Forced Ejaculation! (1 syllable challenge)

I came,
you did not.
I blame
the old cot.
You said
'You have shot!'
I felt
such a clot.

That spring
felt like glass;
it jabbed
up my arse.
My balls
just let blast.
I know;
it sounds crass!

Just give
me a min.
Is it
such a sin?
Let me
get back in;
I swear
You will grin!
