let me turn your fantasy into fiction

Please do my wife. she is 45, i am 60, my cock is too small and not stiff enough tomake her come. she is a very pretty redhead bbw who likes to read romance novels. I think she has a secret fantasy to be taken powerfully by a big man with big muscles and big cock. she is shy and somewhat passive to sex with me. my fantasy is to see her seduced and fucked while i stand by helpless to stop him or her. Her fantasy lover can be named Derek, or Marlon.

her name is Jenny and mine is Johnny.
hope to see you write this up. thanks.
