possessiveness & denial
Good ideas from UKResearcher
In order to deal with the potential for possessiveness like her previous
lover, it is probably best for Sue to make sure Frank knows she still
has active & good sex life with you, loves you and wants this be
an enhancement of your relationship. So it's maybe best to keep
the denial aspect a secret from Frank.
That being said it might be fun to set up an "ownership" schedule
between you and Frank (a matter to be kept completely hidden from
Frank), to facilitate her request for being able to have spontaneous and
unplanned sexual encounters between her and Frank.
You could have her from 9pm Sunday to 11:30pm Monday (or whenever
your last sex is on Monday night) and the rest of the time she would
belong to Frank so she could have her unplanned lunch/evening sex with
him.
Another dimension to the denial could be linking to her monthly cycle. You
could make additional denial periods around her ovulation. Consider the fact
that Sue uses an IUD. There is continuing controversy over exactly how
IUDs prevent pregnancy. Some researchers think pregnancy is controlled
by preventing conception (fertilization), while others believe that the devices
prevent embryo attachment to the uterine wall (implantation).
If the latter is true, you can titillate you mind with the thought that Frank
might have already fertilized Sue's egg one or more times. For a really hot
turn on, you could time denial periods to that only Frank's semen would be
allowed to get to her eggs. A kind of limited pregnancy play, just
something to think about...
Can't wait to hear what happens!
