Your old self is disgusted, but the sexual urges you feel just keep getting stronger. Your penis hardens fully and the male striding (if that's the right word) towards you notices. You forget your inhibitions and kneel down in front of him.
The male soon gets the message and presents his cock to you. You can smell its muskiness, see the hanging bulges of his large testicles, and you can't wait to take it into your mouth.
First you take the cock in one hand and bring it to your mouth and lick the tip a few times. As you do this you can feel it harden in your grasp. Once it is hard you stroke it with one hand, cupping the other hand around his hanging ballsac and suck on the head.
You enjoy the taste of the male flesh in your mouth and ignore the little voice in the back of your mind telling not to carry on. You grip the male's ass and slowly move your head further down his shaft until you can take in no more. You suck hungrily and bob your head up and down. You tongue plays along the cock, eliciting frantic moans from the male.
Soon your efforts are rewarded as spurts of hot, thick cum splash into your mouth and down your throat. The taste is slightly salty and you enjoy it, milking the cock for all it's worth. Soon no more comes out and the cock softens.
