Mums getting more cock!

Im at this very minute listening to my mum having a fuck session with her toyboy!
Mum seems to be getting a lot more sex than me for sure, shes got this new fella whos only 18 but has a massive fat cock, much bigger than mine and makes me feel very jealous, and she has been having him round regular day and night.
She clearly is having a good time at the moment as i can hear her screams and groans of pleasure, he sounds like he is having a good time too.
I would love to go in watch as ive never seen her being fucked by such a big cock it really turns me on, ive seen my mum many times before with different guys and women, she really does have a high sex drive an she certainly aint afraid to show me that, often walking the house in sexy underwear and on the occasion naked.
