I rarely masturbate alone, but I consider sex with my husband to be masturbation, because I have never cum with him without rubbing my clit, or using a vibrator on it. He pretty much functions as a SMALL dildo, as I cum better with something inside of me and pumping me. Dildo's are ok, but not as good as something real and warm.
When we do this, I am thinking about a movie we have and a situation where I am always restrained and unable to do anything about what a group of men want to do to me. Mostly I imagine them doing "experiments" on me like forced repeat one after another orgasms with various types of dildo's and vibrators and making notes on clipboards, or injecting sperm from various soures in me with syriinges to see if I get pregnant and how hard I cum based on the source of the sperm, (don't ask it causes problems, remember this is a fantasy), sometimes they repeat breed me to anyone they can find nearby (always includes homeless unkempt types and they talk about someone of my social status getting knocked up by this homeless guy), they do nipple "......" (not real serious pain, but interesting things like tying rough string around them and suspending them with weights, etc), plugs in various holes, mouth gags that allow them to push their cocks through but I cannot close my mouth, virtually anything they want to do to me and I have no control over it.......doing this and rubbing my clit manages to get me one decent orgasm before hubby cums in his condom (the only way he gets inside of me).
All of that has to FLY through my mind in about a minute to get my orgasm in before hubby dribbles in his condom. He can sometimes barely get inside of me before he starts cumming, ever since I started having affairs with Lovers. Most of the time, I am already full of someone elses sperm, which pushes him over the edge quickly. LOL
