A chubby and big-headed cock destroys my ass in a public park.

I am sitting at a table in a lonely public park relaxing and enjoying the silence and tranquility when a stranger approaches me and starts talking to me. i am left unable to move when he asks me if i like big cocks and if i would like to play with a good one for a little while. my tail starts to get hard and my mouth starts to salivate when i see that stiff cock. could there be something more morbid than an unknown cock breaking your ass?
