Harem groweth more!

Samantha was the first you saw and she was captured in the throes of the addiction going into the next stage, 4B. She was profusely sweating, her body was completely drenched, and her hair was matted and damp. Even the look on her face, in her eyes, was a mixture of intense need and craving and a desire to get fucked. By you. You knew that she had been fucked by you, then by your dad, and now she needed you again. You also knew, from the way her eyes were rolling in the back of her head, you had all of 5 minutes to nut off in her or she would drop dead. Plain and simple.

"Fuckin' hell..." you muttered and with little fanfare, you grabbed the second of three injectible pens and without regard for how much this would hurt in a few minutes, you dropped your pants and boxers and placed it next to your cock. The first needle jabbing into your skin caused you to go slightly pale and your mother, caught in her own bodily cravings, made a start out of concern for you. You shook your head as the second needle jabbed quickly on the first.

"FUCK!"

The third and fourth needles pierced your skin and the chemicals tracing through your blood immediately had their impact. You could feel your cock straining and it became even more engorged with blood and she looked at it with a look of fear and anguished need. You doubted you would've even heard her if she told you to stop.

"Please..." she whispered, holding her legs as wide as possible. You looked at her pussy, her lips were bright pink and her flesh was strained as she spread the lips apart. You could see how sopping wet she was but you didn't even care as you lined your monster head against it and slammed in. She immediately screamed and nearly knocked herself out as her head smacked against the floor behind her.

You didn't care, a knocked out girl might be an interesting lay. All you cared about was your cock and your testicles that were immediately pumping out more and more hormones and priming your body for a massive cumdump into her body. She shook from your thrusts and began to match with her own, rapidly pounding you as you pounded her into the ground. You barely saw your mother finger-fucking herself as she watched her son rutting like an unhinged animal. Your focus was on the woman in front of you.

"You're fucking mine now, bitch," you grunted and Samantha shuddered as she came hard for you. You kept saying some of the dirtiest, degrading things to her and she responded by swearing anything, everything, throwing her body to you and making her yours. You knew one of the side effects to the **** now coursing through your body was the jacking of your pheromones up way past normal male levels and the cum addiction caused her to instantly react at a basic, primal level. She was a brilliant mind but all she was now was your woman, your fucktoy, and she would never be free from that again. You could smack her around, burn her with wax, beat her senseless, and she would never waiver in her devotion to you.

You pulled out of her and before she could respond, you grabbed her waist and flipped her onto her hands and knees before you pushed back into her. Your hips were moving as if possessed and you pushed her into the ground, her mouth open and her tongue wagging as you thrusted into her again and again. Her breasts were flopping wildly as you dug in deep and with one last push, you went as deep as you could. She instinctively arched her back and let out a scream as your cum shot into her body before she collapsed. You weren't done, though, as you continued to pump her full of cum for the next two minutes. Her stomach extended, somewhat cartoonishly, as you pumped more and more until her body couldn't absorb or hold any more and as your cock slid out of her, she squirted and her load mixed with yours caused you to slip a little, landing on your butt. Your mom immediately dove between the girl's legs and began to lap at the cum on the floor.
