I've been reading this site for quite a while and I just now got up the courage to share.
I begin by somehow visually or mentally stimulating myself. I'll read some erotic literature, watch a little 'soft porn' on television, maybe even have some phone sex. During this preparation time I am usually charging up my trusty electric toothbrush. I let myself become as wet and turned on as I can stand, then proceed to retrieve my toothbrush. I lay the toothbrush on the bed and take off all my clothes and softly touch my body. I then lay on the bed with my knees bent, legs spread wide. I turn the toothbrush on and play with my nipples with it. I apply the toothbrush to my throbbing clit, teasing myself turning it on and off. Sometimes my pussy starts to ache for penetration, so I'll reach into a drawer by my bed and grab a fat marker. I push it into my wet pussy, at first shallowly pumping it in and out or wiggling it around with my finger. Then I push the marker in my cunt all the way in, apply even more pressure to my clit with the toothbrush, and let go of the marker and grip one of my tits. I squeeze my nipple between my fingers, while squeezing my pussy as tight as I can. I cum so hard that I usually let out a yell of ecstasy.
I usually think about a girl eating my cunt, or masturbating me. I've never been with a girl, but I so desperately want to be! I think I'm bi... haha but thats another story.
