Limerick?

Once a fellow who gladly would savour

His gaseous girls rectal flavour

Inhaled her bottom gusts

and they filled him with lust

Made more foul by the beans that he gave her

Got turned on when his wife started farting

He’d breath in butt aroma

Made him quite a loud moaner

He’d explode when her butt cheeks were parting

Sorry

Not sorry
