Object of masturbation.
Join in, or be Objectified.
We all have different sex drives and stressful days can very between partners. The odds of a couple being “horny” at the same time are unlikely.
Not in the mood, or feeling aroused at the moment?
Have a standing agreement that you are good with your partner playing with themselves next to you. That way, they can self-pleasure with you in mind for their arousal.
Why have them fantasizing over images or videos of other women. They can think of you and visualize your body while they masturbate.
Many times this will be stimulating for you, and may decide to help them out…
or join in with your own self-play.
