Peter Parker, better known as Spider-Man, woke up feeling strange. He felt lighter, as if he was floating. As he opened his eyes, he noticed his room was different.

He got up, his movements felt awkward. As he reached the mirror, the reflection staring back at him was not his. It was Mary Jane's.

In a panic, he tried to wake himself up, believing he was stuck in a dream. But the reality was far more complex. He had somehow swapped bodies with Mary Jane.

Meanwhile, Mary Jane awoke in Peter's body. She too was shocked and panicked. She quickly realized the predicament they were in.

After the initial shock, they tried to adjust to their new lives. Peter had to manage Mary Jane's acting career, while Mary Jane tried to cope with Peter's superhero responsibilities.

Things took another unexpected turn when Peter started feeling sick. He thought it was just a side effect of the body swap, but he was wrong.

When he visited a doctor, he was shocked to learn that Mary Jane was pregnant. He was going to give birth to their child in her body.

The news hit Peter hard. He was overwhelmed and scared. But he knew he had to stay strong for their child.

Meanwhile, Mary Jane was struggling with Peter's superhero life. She had to deal with villains and protect the city, which was physically and mentally exhausting.

But the hardest part was not being able to be there for Peter in his time of need. She felt helpless and wanted to switch back.

As days turned into weeks, Peter adjusted to the changes in his body. He felt a connection with the growing life inside him.

He would often talk to their child, promising to protect and care for them. He also started reading up on pregnancy and childbirth.

Mary Jane, on the other hand, was doing her best to fill Peter's shoes. She was learning to control her powers and fight villains.

She also missed her body and the life growing inside it. She wished she could feel their child's movements and share the experience with Peter.

As the due date approached, Peter's fear and anxiety grew. He was worried about the birthing process and the wellbeing of their child.

But Mary Jane was there to support him. She assured him that he was doing great and that she was proud of him.

The day finally arrived. Peter was in labor. He was scared, but he knew he had to be brave for their child.

Mary Jane was by his side, holding his hand. She was there for him, just like he had been there for her during their battles.

After hours of labor, their child was finally born. Peter held their baby for the first time, feeling a surge of love and relief.

Mary Jane looked at Peter and their child, feeling a mix of joy and sadness. She wished she could have been the one to give birth.

A few days later, they woke up in their own bodies. The swap had ended. They were back to their normal lives, but with a new addition.

Peter was relieved to be back in his body. He missed his powers and the freedom they provided. But he also missed the connection he had with their child.

Mary Jane was overjoyed to be back in her body. She could finally hold and nurture their child. She felt complete and content.

They both realized that their experience had made them stronger. They had a deeper understanding of each other and a stronger bond.

They also learned to appreciate their own bodies and abilities. They knew they could face any challenge together, as long as they had each other.

They were excited about their future as parents. They looked forward to raising their child together, to teaching them about love, courage, and strength.

Despite the hardships, they wouldn't change anything. They knew their experience had made them better people and better parents. They were ready for whatever life had in store for them.

The birth of their child marked a new chapter in their lives. A chapter filled with love, joy, and the occasional superhero battle. But they were ready.

They had traded lives, experienced each other's struggles, and come out stronger. They were no longer just Peter Parker and Mary Jane, they were parents. And they were ready for their new adventure.

And so, they started their new life as a family, stronger and more united than ever. Their love for each other and their child was their greatest strength.
