You suck his cock.

The warm, throbbing member in your hand is, quite possibly the greatest cock you have ever laid your eyes on. What's more is, the more of that thick liquid that coats it covers and soaks into your hand, the more your own sexual arousment grows. The fire in your nethers grows hotter and hotter, as you feel your own wetness running down your thigh. Your mouth waters as you start to slowly jerk it off. You do this for some time but the more you touch the more you want to do, soon you can not control yourself any longer.

You open your drooling mouth and eagerly lick the tip. You thought that surely the viscous liquid would have a foul taste, but you were wrong. It was thick and sweet, like a form of honey. And as the small amount slid down your throat you felt the blush on your face grow redder as you grew wetter. Free of all restraints, you engulf as much of his cock as you possible can without gagging, which isnt much. More of the thick ooze is slowly sliding down your throat, increasing your arrousal and putting you into a wild state of lust. Your bobbing your head on the monster cock, pushing it into your gag reflex while jerking its base as you cough and gag for air.

But you cant stop, not even for air, as it couldnt be as sweet as this large cock in your mouth or the thick fluid on it. You gag yourself harder and harder trying to fit as much into your throat as possible, you never take more that half but you try to make up for that by stroking the half you cant swallow. Soon the beast is humping into your mouth, your hand has gone from jerking to trying to keep it from jamming all its cock in. Its thrust grow harder, and faster. Your swallowing more of the fluid as well, making your pleasure hotter and hotter, even as the tears roll down your face. Soon the beast gives deep thrust as all your hard work is rewarded as it fires stream after stream of seed down your throat.
