Yes, the pairing is Gohan/Bulma, but t isn't like one of those wham, bam, thank you ma'am type story. I'm a fan of weird pairings of anything except yaoi.
Disclaimer: *stares* Yeah right, you think I'm… Hahahahahahaha!
"Um, Mom, I'm home," Gohan said as he entered his house. "And I have something to tell you."
"Gohan, you're all right! Thank God! Where's your father though? I have to tell him something," screamed Chichi.
"That's kind of what I wanted to tell you," continued the demi-saiyan, tears forming in his eyes. "Dad died during the Cell Games to save Chikyuu."
"What!? My Goku is dead!? Oh God! My water just broke! I have to get to the hospital!" shrieked Chichi.
"Huh? You're pregnant? Oh shit! I'll get you to the hospital as soon as I can! Just try to hold on hold on." Gohan grabbed a hold of Chichi and flew as fast as he could to the Orange Star City General Hospital.
"I need a doctor right now! Please hurry! My mom is pregnant!" he yelled at the secretary.
"Shh! Use your indoor voice. You're in a hospital, after all. Well, nearly all of our rooms are unoccupied. I'll get a doctor for her right now," said the secretary calmly. Sure enough, a doctor, Dr. Raspion, came to get Chichi.
"Gohan," Dr. Raspion said, "this will probably take a while, so your mother said to go to the Briefs' house until further notice."
"Okay, thank you Doctor," Gohan answered politely. "I'll head over there right now." He walked out through the automatic doors and, once he was out of sight of everyone, flew towards Bulma's house. After he punched in the appropriate password, Gohan noticed all of the Briefs and Vegeta gathered out in the front lawn.
"Gohan!" yelled Bulma. "It's about time you got here! You almost missed Trunks leaving for his own time! Where's Chichi?"
"Mom is in the hospital right now. She's giving birth right now," answered Gohan.
"Chichi was pregnant? I didn't know that. Why didn't you tell me?" asked Bulma.
Gohan replied, "I just found out today myself, about twenty minutes ago. She told me to come here after I brought her to the hospital."
"Onna, I'm wasting time right now waiting for Trunks to leaver, which he can't do while you're yapping about a pregnant woman!" yelled Vegeta.
"I probably should get going now, Mother. "Good-bye Mother, Father, Grandma, Grandpa, Gohan. I'm off now," said Trunks. He got into his time machine and, with a final wave good-bye, disappeared into the infinite reaches of the time/space continuum.
"Happy now Vegeta?" asked Bulma, with a slight tone of anger in her voice.
Vegeta responded, his voice full of apathy, "Very." He strutted into the house, followed by Dr. and Mrs. Briefs.
"Bulma, before you explode with fury, I'll just tell you that I'll probably be sleeping in one of the guestrooms for the next few hours," said Gohan. He walked into the house, leaving Bulma, furious at Vegeta's rudeness, and Chibi Trunks, who just sat there looking confused.
Twenty-seven hours later:
"Man, that was a nice rest," yawned Gohan. The demi-saiyan walked out of the room and realized that he couldn't sense Bulma's ki anywhere within a quarter-mile radius. He walked around the corner into the front hall only to bump into Mrs. Briefs.
"Oh, Gohan, honey. I was just checking to see if you were awake yet. Bulma left for the hospital about three hours ago to help Chichi out. They should be back anytime now," said Mrs. Briefs. The front door then opened to revealed Bulma standing there with a baby carriage containing a baby in her arm.
"Hey Gohan, you're awake finally. Guess who this is in my arm right now. It's your new baby brother, Goten! He looks exactly like Goku. Do you want to hold him?" asked Bulma as she handed Gohan the mini-Goku.
"Sure, Bulma. One question though: Where is my mom?" asked Gohan.
Tears started to form in Bulma's eyes. "You see, Gohan, your mother had leukemia, which is a type of cancer, and she died after giving birth to Goten."
Gohan was also silently sobbing now. "Damn it! Mom is also dead! I never even got to say good-bye! Haaa!!!" Gohan's hair changed from pitch black to a brilliant gold, and his eyes to a kind of teal. His hair grew longer, he grew slightly taller, and static energy formed bolts of energy surrounding his body. But he wasn't done there. Gohan's hair grew in size until it reached the length of Radditz's hair in proportion to his body. The young super-saiyan grew about an inch and his eyebrows disappeared altogether, making the tops of his eye sockets seem to bulge out.
Them, just as quickly as it started, the process reversed itself as Gohan's hair shrank back to normal size and turned black again. He fell unconscious in the front hall, Bulma staring in awe.
I know it's pretty short and fast-paced, but it's my first story, and it's 2:30 AM right now where I live, after all. Please review.
