Any suggestions?

Mistress, will you advise me what might work best ? I need a good spanking while my wife and I are having intercourse.
Her arms are too short to use her hands effectively . What do you suggest ? Flogger ? Strap ? Something else ? Alternately I like to get my ass filled and fucked during intercourse .
Something big/thick enough. Is there something that could help her reach to do this ?
Please advise . Much appreciated .
Thank you .
Mark

I got this email Saturday at 10 pm. Was the wife asleep or were they waiting for my reply before starting to do it? 😆 I’m not “Dear Abby” but I’m sure one of you can advise him!
