Liara noticed the change in position as Alessca's breasts and face pressed against her back.  Alessca's cock shifted only slightly, but the angle began rubbing vigorously against her clit and her internal button.  The waves of pleasure were starting to grow in intensity.  Liara became light headed as her breathing and moaning grew faster, her body writhing under the relentless pummeling from Alessca's throbbing cock.<br/><br/><em>"I'm going to orgasm.......I can't control it."</em>The Andorian exclaimed from behind them both just as Liara felt Alessca's rhythm start to gain momentum.  Tarah's frantic thrusting pushed Alessca deeper into Liara's already gutted vagina.  Liara gasped as she felt the electricity in the room jump between the three women.  Alessca's formed pussy ring around her cock and her body pressed against and inside her, forced Liara to the edge of her tolerance.  The wave of orgasmic energy running through Alessca from Tarah set off Liara in a way she had never experienced before.  She came with the power of man and woman at the same time.  Her pussy clenched and massaged Alessca's firm shaft as a vaginal orgasm ripped through her body, joined immediately with a release of the full sacks of cum hanging below her shaft.  Liara screamed as her body shook and writhed, twisted and convulsed through the uncontrollable orgasm that ravaged her body.<br/><br/>After a few long minutes of wondering if her heart might stop from the intensity of the orgasm, Liara's muscles finally released her and she collapsed limply onto the console.  Still held up by the pressure of Alessca's body against hers, her body shut down and Liara literally passed out.
