The time had come for Abigail to finally begin her plan. All the preparations were complete and it would be only the matter of time of executing it. She giggled in thought of how you would react...but it would be all worth it for her and you in the end.
"Abby...you seem...unusually happy today," you observed.
She cocked her head. "What? I'm always happy silly!" she smiled.
You shook your head. "No...like, really happy. Are you excited to see my mom or what?"
She giggled. "Oh I'm excited to see your mom alright..." she smirked.

You could never understand her. She was possibly the hottest girl in the school but at the same time, she was a silly one at that. You liked it though, it was better than having a bitchy or a quiet girl with you all the time. You only wished she could spend more time with him doing it than having a conversation with your mother. Your mother definitely liked her and have always praised you for grabbing the best girlfriend. Her goal is to see you and her one day marry. You chuckled in thought of that though it was highly likely.

You finally reached your house and the first one to open the door was your mother. "Hey my little boy! Hello Abigail!" she greeted enthusiastically. You rolled your eyes with slight embarrasment; however, she always liked it when you bring your girlfriend home.
"Hi Mrs.," Abby respectfully greeted back.
You sighed and walked into the house. Abby followed in as your mother closed the door.

The time for Abigail's plan had begun. She grinned. ", I've got something to show you..." she whispered into your ear. You glared at her wondering what she could be planning. Your mother hummed happily into the kitchen ready to make some lunch for you and Abigail.
"What..." you pressed on.

"You know how I told you my grandmother was a witch and all?" she reminded.

You rolled your eyes. "Sure...I believe everything you told me..." you replied sarcastically.
She huffed a little. "It's totally true! I'm going to prove it by doing something I've planned for a long time..."
Your eyes widened. "Look...Abby, don't make a scene please! Let's go into my room if you plan on having sex..."

Abigail sighed knowing that you wouldn't know what she was talking about until you see her. She spoke into your ear in a very erotic tone. "Get ready for a new sexy mommy! Slimera!"

In instant, you gasped as your girlfriend completely melted into a puddle of fleshy goo. "W-what the hell!!?"
Your mother was still humming, unaware of the fate planned for her. The puddle of goo shifted toward the kitchen. You attempted to stop by putting a foot onto the puddle; however, it simply slided by. It quickened its paced and before you could call out to your mother in warning, the goo had touched her leg.
"Gotcha!" the goo sounded in a distorted voice.

"Mom! Watchout!" you warned, but it was too late as the goo leaped,expanded, and enveloped your mother's entire body. Her screams quickly became muffled sounds as your mother panicked and started to shake it off.

The goo retaliated only more as it tightened its hold on your mother. The shape of your mother was confined to the goo and soon your mother's muffled screams became moans.
"Oh god...Abby! Stop this! You don't have to prove to me anymore! Please, just stop!!" you shouted.

The goo responded back. "I can't do that...I've wanted to do this for a long time...I want to push our relationship further!!" The goo began to flow everywhere and your mother moaned even louder. Soon the goo began moaning as their bodies assimilated.

Quickly, you moved into the kitchen to try to stop it; however, a stretch of goo pushed out of the mass and held you to the floor. "Ugh! Abby stop it now!!"

"It's done...it's almost done...we're almost complete!" a new voice appeared. You realized it was your mother and Abbigail's voice who were talking, only it was in perfect sync. The goo along with your mother finally paused and completely dropped to the floor like liquid. It rebounded and a new shape began forming from the puddle. The stretch of goo receded back into the new form and you started to tell what the form was going to look like. In shock, you couldn't help to have a boner as well as you saw a new person being created as the goo faded away.

You couldn't believe your eyes as you saw the whole process. You gulped to think of what happened to Abby and your mother.
"M-mom? A-abby?"

She smiled. "I'm not Abby anymore...I'm your new, sexy mother..."
"O-oh god...wh-what have you done?!"
"I'm simply doing what I've always wanted...Getting closer to you. That's why I've been getting close to your mother because I needed to know her personality in order to sync with her. Now that it's done...I feel so much better...It feels so incredible to suddenly become a mother..." she described.

You quivered. "A-abby...please...give me back my mother..."
She chuckled. "Oh I'm afraid that once it has finished...it's permanent...start expecting to call me mommy, because I'm technically not Abby anymore..."
"You...you're a sick bitch..." you muttered.

She rolled her eyes and shook her head in disappointment. "Come on...you can say whatever you want but you're mine...trust me...you'll start to like this and start forgetting about your old saggy mother..."
