"I got one last idea before I let you change me." Mark said.
"What's your idea?" Rachel asked as she shifted her whole body to look at Mark. This made her slight swing with force so she had to leave her breasts stopped jigging before her sight stopped jiggling and clear up.
Mark pulled up a dark pussy and dark ass. "I have an idea. What if i could sit in your butt pussy. Full body. I know you really liked it earlier and I know I will be set off too as my dick is always hard touching my breast balls."
Rachel just stared at Mark. "Damn, thats a ..." She paused. "A great idea lets try it!"
Mark glanced over to the clock to see that it was getting late. "I need to make a phone call first." Mark quickly stepped out to grab his cell phone. After he stepped out Rachel reached down to blend a few chocolates and eat them. She felt her ass grow outwards. Continuing to eat more she stopped temporally as her ass reached out to be two large beach balls each. She used her hands to move her breasts to gaze into the mirror to barely see her large ass.
"So you already started?" Mark asked as he stepped back into the room. He picked up more dark ass and dark pussy chocolates. "Time to make them bigger." Mark stated as he combined the chocolates.
Rachel looked over to Mark who gave the chocolates to his girlfriend to eat. After she finished eating a few more Mark smiled. "I think I can finally fit in your pussy ass." Mark gazed over her ass cheeks being big enough to fit a full human body inside. Mark turned and took the chocolates to place them on a desk that was on the side of the bed.
"What are you doing?" Rachel asked.
"Well I thought you would be on your bed while I get in your pussy ass." Mark said. "Since I believe you might fall asleep due to how late it is and I would be something to be able to sleep in it too."
Rachel's eye breasts blinked. "Guess that makes sense." She said. Mark pulled the top blanket off the bed to have Rachel lay down onto the bed. She laid on her left side with her breast looking to the side. She had her head on her pillow. Finally she twisted her giant butt to be upright.
Mark grabbed The blanket for the bed and put it over Rachel. "Ready?" Mark asked after he wrapped his
girlfriend up. She only had her large rear uncovered as well as her head and breasts so she could see.
"As well as I will ever be." came the response.
Mark took his shirt and the rest of his clothes to nervously step forward. He took one foot and put into the opening to feel the wetness and warmth surprisingly. Rachel started to moan. Mark then took the plunge as he fully stepped in making Rachel moan even more.
He was quickly halfway in and was very hard himself. His breasts on his ass. No that wasn't fully correct. His butt breasts and breast balls was stiff and hardened. He continued to push father into his girlfriend to only have his sticking out. It was at that point both passed out due to the extreme about of pleasure.
