He commands you to suck him

"Sister," begins Beren, "I am going to take my cock out, and you are going to suck it."

"What?" you gasp.

"You are going to get down on your knees, take my cock into your mouth, and pleasure me. You are going to love doing this. It will seem as if one of your greatest desires is coming true."

You let out a moan of lust as you fall to your knees before your brother. Your mouth waters with anticipation; it is as if you've dreamed of this moment for years. You wet your lips and look on impatiently as Beren unbuckles his belt and opens his trousers. His thick cock bounces free, the fat, almost purple head peaking out from the soft foreskin. You take him in both hands, stroking the shaft and kissing the swollen head. Your lips open up around him, skinning him back as you slide over his bulging tip and down his shaft

He is salty with sweat, and so big he seems to completely fill your mouth, your lips stretching to accomodate him. Despite the fact that you've never seen one before, this cock seems made for your hot, wet mouth to slip over and coat with your spit.

You begin to bob your head on him, taking as much as you can without gagging. Beren watches you suck him with a triumphant smile on his face.

"Very good, sweet sister. Your lips are like a vice, your mouth, a little heaven." He rests his hands on your head. "Faster now. And do not spare your hands on cock or bollocks."

Sucking your brother's swollen hardness is like sitting by the fire or enjoying your body in the bath. In fact, as you bob your mouth on him, you slip one hand between your thighs and begin to touch yourself. Your delicate furrow is slick with your juices, your clit standing out against your fingertips.

"Oh, Beren," you moan around his cockhead. "It's so delicious."

"Want a real treat, Jordan? Get your mouth down there and suck at my bollocks. Feel how heavy with seed they are..."

"Ohh, yes brother," you gasp, running your tongue down his shaft to his heavy stones.

"Good girl," he moans, stroking your hair.

You chase his balls' weight with your tongue before catching one gently in your lips and gently suck, even as your hand continues to work your brother's spit-slicked shaft. The quiet road fills with the sounds of your lewd slurping and moaning, getting louder as you return your mouth to Beren's cock and begin to suck him off quite vigorously. Your fingers at your velvet folds are awakening your pleasure, and Beren, groaning above you, seems to be nearing his own climax.

"You must be truly thirsty, sister," says Beren. "My seed is churning to spill in your mouth."

"Yes, Beren, yes," you moan. "Let me taste your cream..."

He groans at your submissive words, and suddenly you feel a trickle of fluid at the tip of his cock. It is immediately followed by a torrent of hot, thick cum, wave after wave pumping out of your dear brother's throbbing member.

You swallow again and again, swirling the creamy load with your tongue as it flows downward. Your fingers plunge with new urgency into your wetness, forcing your kneeling legs slightly farther apart. A trickle of your own fluid falls downward onto the road.

As you finally swallow the last of Beren's seed, you look up at him. He returns your gaze mischievously... Clearly his fun is only just beginning.
