Vilgax's Plan

Sorry for the long wait I had major internet problems and exams in college. This is the final chapter of the story, so please enjoy.

Chapter 5

Ben tossed and turned; finally he just woke up and decided to check on Gwen. Gwen was also sleeping fitfully, having had her mind twisted by Vilgax, her fingers were constantly rubbing her pussy. At first Ben thought she was awake while masturbating, but then he realized she was sleep-masturbating. The cousins were in the woods about a day’s walk from where Grandpa Max was waiting worriedly about his two missing grandchildren. Max had been sent a note form Vilgax right after Ben had gone after Gwen. The note was a hologram of Vilgax, who proceeded to tell Max that Vilgax’s final revenge would soon be complete. Max feared what Vilgax would do to his grandchildren because he had already guessed the best revenge Vilgax could inflict upon him was if something happened to his grandchildren.
As Ben looked at Gwen a rising heat started to filter through his body and into his loins. He felt a sudden urge to activate the Omnidrix. The flash of green light from the alien transformation awoke Gwen. Stumbling to her feet she spotted Ben as Stinkfly advancing towards her with a dazed looked in his eyes. Gwen in her lust induced state could fell the rising need for sex from the alien Ben. She slowly lowered herself to the ground and pulled open her nether lips for Ben to get a full view. She softly said, “That’s it Ben come here and fuck me.”
Stinkfly stood above her and a green cock emerged from a sheath in the middle of his tail. He slowly entered into Gwen as she moaned from having her desires answered. Stinkfly moaned too, from having his toll surrounded by warm, wet heat. Awkwardly and slowly Ben started to thrust in and out of Gwen. Gwen wanted more speed, but realized this was her cousins first time and he was fucking her in an alien’s body. She thrust back at the same speed as Ben’s set pace, but soon the need for more crowded out her acceptance for her first time cousin. She cried out, “Faster Ben, faster, fuck me faster and harder.”
Ben increased the pace and brought his face close to Gwen’s face. He brought his hands up to her breasts and started to tweak her nipples, bringing new moans from Gwen as she orgasmed. His alien tongue, along and thin almost vine like apparatus, launched itself into Gwen’s mouth and wrapped around her tongue in a weird French kiss. Gwen surprised at first at Ben’s initiative, nevertheless returned the kiss and wrapped her arms around the back of his neck as the two fucked. Ben felt a fire start to spread to the tip of his cock and tried to hold for a while, but eventually he felt the need for release. “Gwen something is happening”, he said in Stinkfly’s high pitched voice.
Gwen confused at first felt herself approaching orgasm again and realized Ben had never cum before. Giggling she said, “Ben you are going to cum, wait and cum with me.”
The cousins picked up their speed to animal levels as flesh loudly slapped against flesh. Suddenly lightening struck and they both cried out. Gwen’s pussy clamped around Ben’s alien cock and hot liquid surrounded his member, Ben then pushed in as deep as he could, stopping when he touched the edge of Gwen’s cervix. His member spat out string after string of green cum and Gwen’s pussy milked every drop into her womb.
Finally it was over after an hour of sweet love making the two separated. Exhaustedly the two curled together as Ben turned human again. Deep inside Gwen however the fertilized eggs started to grow and Vilgax’s revenge against the entire Tennyson family had finally arrived.
