I am quickly losing my reluctance to fuck M with me on top. He has always enjoyed having me on top, but when he would pull me onto him, or tell me to get on top, I would whine "But I don't like to be on top," before grudgingly climbing on. However, I have been orgasming consistently while riding M lately, and it's gone a long way towards abolishing my shyness and insecurity.
He likes when I take the initiative and climb onto him, but I'm not quite there just yet. I've done it, of course, but it's still not my preference. I'm coming around, tho, and I've been doing it much more often. I'm not sure if he's noticed. I know M's noticed all the orgasms because he's said to me, "I don't know why you always complain about being on top, you cum so much when you're on top." Heh heh
And my god, every time I do wedge his cock into me, easing myself down onto him, it makes me sharply inhale. I need a second to adjust to it before I begin to work myself on top of him. It makes no difference how soaking wet I am, or even if he's fingered me, M's cock still stuffs and forces me open. That first pierce is so delicious, it makes me concerned about him fisting me, and that feeling possibly going away.
Once I've accustomed my cunt to M buried up inside of me, I begin to slide myself on his cock. I get an image in my head of my pussy lips gripping at his cock, because that's the way it feels. My cunt is like a hungry mouth sucking his cock up into me, desperate for every inch. I don't bounce so much as I grind my clit down against him and buck my hips to rub the head of his cock across my g-spot and bumping my cervix.
M doesn't just lay back and motionless, his hips thrust upward matching my rhythm and intensifying the burning sensation that spreads through my body. My face and chest get flushed and my legs straddling his hips shudder so that even M can feel it. I throw my head back grunting and moaning at the ceiling. I dig my fingers into his chest and often he'll have to place his hands on my waist to still me and stave off his own orgasm. And when I've cum I collapse on top of him, panting and sweating, unable to speak.
Sometimes he won't allow me to stop until I've cum several times. Once I've had the initial orgasm it's much easier for me to cum again, so M will nudge me back into a sitting position and instruct me to "Make [myself] cum again." And, still cloudy headed, I resume rocking my hips, both of our thighs soaked with my juices, and quickly bring myself to another orgasm. He has made me do this over and over before, exhausting me. I can ejaculate doing this. My body well let out a deluge of wetness that drenches M and the sheets beneath us. M has teased me about how I get so wet that his balls and asshole get soaked with my juices.
No doubt M will be pleased to learn of my changing taste for riding him. It's difficult to convince myself that I would rather whine futilely than slither onto a gorgeous boy and have my pussy jammed with cock until I come to a screaming orgasm.
Next I think I have to tackle becoming proficient in anal while I'm on top! ;)
