You don't know how, but you somehow manage to avoid being scooped out of Sam's pussy by the giant, pink intruder that is your mom's tongue. You're not quite sure if it's a victory though, because it means that you get to experience the unpleasantness of being caught up in the middle of an orgasm. It goes quiet for several minutes, then you feel a tingling, and you're suddenly lying on the coffee table. Your mom is kneeling on one side, and Sam on the other, between the coffee table and the couch. Unnervingly, both giant women are naked.
"Well, that was fun", Sam says softly.
"Guess you get to live", your mom says, grinning evilly as she looks down at you. "That means, you are now officially our slave. There are two ways this can go. You can either accept that you're now nothing more than a living sex toy, do as your mistresses command and be treated reasonably well..or you can resist...in which case everything we do to you will cause you immense pain. It's your choice", Your mom licks her lips hungrily and smiles.
"You can think about it while you're helping Sam to scratch the itch I've got in my pussy".
You suddenly feel a tingling again. This time however, you grown to ten inches.
"C'mon dickboy" Sam as she snatches you off the coffee table.
Your mom lies down on the rug in front of the fireplace, and Sam slips between her legs and lies down on top of her with you gripped firmly in her left hand. You can only watch helplessly as the two giant women begin to french kiss. Despite being in such a difficult situation, and that one of the giant women is your mom, it's incredibly erotic. After about 15 minutes, Sam sits up and drops you between your mom's thighs. Because of the position of Sam's thighs, you're completely trapped between the two women.
"Kiss our pussies, slave", Sam says with a smile. "Or would you like me to break every bone in your body..and then stuff into you mom's pussy and use you for a dildo?" she asks when you just stand there and glare up at her.
Slowly, you walk forward, then get on your hands and knees and plant a kiss right on her slit.
"Good boy, slave", she says. "Now do it to mommy".
You want to resist, and have to fight of a strong wave of nausea. But at the same time, you have no desire to find out if Sam was serious about breaking all your bones. So you do as you're told and kiss your mom's pussy.
"Good", Sam says. "Now lick it. All over. Then you can find out what it's like to be a dick".
