Sarah continues to cum

Adam couldn't breathe, and his strength began to fade quickly due to his panic and the lack of oxygen. His head was pushed down on his sister's huge cock, with an unexpected **** that he was unable to counteract. Adam could feel the thick cock pulsing against his tight throat, as spurt after spurt erupted.

However, as seemingly endless amounts of cum were pumped directly down his throat, he felt a new sensation. Unbeknown to him, inside his stomach Sarah's cum interacted with the Growth X pills he had taken earlier, giving him energy and strength. The cum reaction empowered the pills to begin transforming his body much faster and more radical than otherwise would have been possible.

Adam's will was reinforced, as he began to develop a new and strong desire. Adam was no longer content to be pumped full of cum. He craved to taste Sarah's cum with his mouth and tongue. The result was, that Adam tightly gripped the base of Sarah's thick shaft with both his hands, and managed to push himself and his head upwards.

He **** his sister's fuckstick out of his throat and this friction gave Sarah a new wave of pleasure and she cried out in bliss. Another smaller orgasm rippled through her body, and she bucked her hips. Without the tight encasement of Adam's throat, Sarah's cock jerked and spasmed, and was quickly ejected from her brothers mouth, who gasped for air immediately. Her fuckstick twitched and throbbed and shot out another few shots of white streams of thick liquid. The first two hit Adam in his mouth, just as the cock was ejected. The following spurts proceeded to paint her brothers face, plastering it with her jizz.

As soon as Adam tasted the delicious, intoxicating cum on his tongue, he swallowed and orgasmed himself and his own cock erupted. The orgasm hit him with a power and magnitude he had never known before, such overwhelming ****, that combined with his still low oxygen levels, Adam lost consciousnesses.

Slowly Sarah's orgasm subsided. Coming down from her high she opened her eyes, only to see her brother plastered in her cum. Adam was breathing heavily, but seemed ****, his eyes closed. He was completely naked like herself.

Her new cock, her brother, naked, blowing her, now ****: Before Sarah had a chance to grasp and understand the gravity of the situation, her eyes continued to wander over Adams healthy body. Not especially fit or muscular, but not an ounce of fat either, it was pleasing to look at. Her eyes went lower and she spotted his penis. She could see that his penis was still hard, but it seemed pathetically small compared to her massive glory, which, although no longer fully hard and already beginning to soften, seemed to easily surpass three times its length and much more than that in girth. She couldn't help but chuckle and smirk in amusement.
