Chapter 1. Bulma Briefs
Gohan had just arrived back at Bulma's place after another training session with Trunks. He had complete faith in the younger half-Saiyan, but he was still having trouble unlocking the power of the Super Saiyan.
At this rate, all life on Earth will be gone thanks to the Androids. He was the only one left of the Z-fighters and even he can't stop them. Despite being able to go Super Saiyan.
After he placed Trunks in his bed to sleep, he exited his room while closing the door behind him. He then made his way to his room.
On the way, he saw a light coming from a room. No doubt it was Bulma going over something. Deciding to check in on her, he knock on the door.
"Come in." Bulma said.
Opening the door, he saw that his hunch was right. Bulma was at her computer. He didn't know what it was since the back of her computer was facing him.
"Hey, Bulma." Gohan said in greeting.
Looking up from her computer, Bulma said with a smile "Hey, Gohan. How's training coming along?"
Giving a sigh, the son of Goku said "It could be better. Trunks is still having trouble becoming a Super Saiyan."
"I'm not gonna say I know much about Super Saiyans, but even you should know that it doesn't come easy. It just takes time." Bulma pointed out.
"I know, but time is something we are in short supply of. If we don't get stronger, the planet will be nothing but a massive graveyard." Gohan said grimly.
"You'll find a way to stop the Androids, Gohan. I believe in you just as much as I believe in my son. You two are the son's of two greet warriors." Bulma said comfortingly.
"Thanks, Bulma. But despite my power, I stand far worse of a chance against the Androids. And if anything happens to me, Trunks will be the only one to pickup the slack. That's something I'm hoping to avoid if possible." Gohan said solemnly. He trained to become the Earth's protector ever since his father died.
But when the Androids attacked, they wiped out his friends. Even Vegeta was no match for them and he was a Super Saiyan before him.
Bulma could see the troubled look on her godson's face. He had no other choice but to step up to protect the world at such a young age after all those they cared about lost their lives to the Androids.
And she knew that while he was strong, he wasn't immortal. Goku and the others were proof of that and the former was the strongest out of everyone.
Should Gohan lose his life against the Androids, that will be the end of the Son family line. The very line of her deceased childhood friend.
It was then she came to a decision to prevent that from happening. Going over to him, she grabbed his arm while saying "Come with me."
Gohan was a bit confused as to what Bulma wanted to show him. He simply did as she asked and let her pull him out of the lab.

Gohan could only groan in pleasure as he sat on the edge of Bulma's bed while she was on her knees and sucking on his dick.
He honestly didn't what possessed Bulma to do this, but he couldn't say that he didn't enjoy it. The feel of her warm and wet mouth around cock was amazing.
Bulma bobbed her head back and forth on the half-Saiyan's meat stick with great fervor. It has been along while since she last had sex.
Now she was going to do it again with her godson. She was only doing this so she could make sure her friends bloodline didn't end with his son's death.
But the aroused side of her couldn't deny that she was turned on. Gohan was much longer and thicker than Vegeta.
'Those Saiyan genes are really something.' Bulma thought as she continued to blow the young man. She even started to rub her pussy through her soaked panties. This was turning her on even more.
Deciding to kick it up a notch, the blue haired woman brought her E-cup breasts up and wrapped them around the half-alien shlong.
Gohan threw his head back as he groaned from not only Bulma's mouth, but also her squishy mellons. They felt so good around his shaft.
The busty technician's skilled mouth was doing wonders to his dick. It was a wonder that he didn't blow his load early since it was his first time. No doubt his Saiyan instincts were helping him with that.
Bulma has been orally stimulating Gohan's penis for a long while and yet the young warrior wasn't showing any signs of reaching his peak. Not that it matter's as she fully intends to have every single drop of his fertilizing sauce inside her.
Once she pooled him out of her mouth, Bulma looked up at Gohan and said in a sultry tone "Gohan, I can't wait anymore. Lie down so we can begin."
Not trusting his own voice, Gohan did as he was instructed. It wasn't long until Bulma crawled onto the bed and hovered over his meaty tower.
After reaching down and aiming it at her entrance, Bulma descended down until the head of his pillar entered her body. Causing her to moan from the welcomed intrusion.
She was halfway down until she felt her godson reach her cervix. Looking down, she saw that there were ten inches of man meat left.
With a deep breath, Bulma took the rest of his staff into her cunt.
"AAAAAAH!"
Bulma threw her head back and let out a pleasure filled cry as she felt her son's friend punch past her cervix and all the way to the back of her womb. It was a good thing her room was soundproof.
Gohan growled as his former virgin cock was surrounded by Bulma's warm and wet pussy. Letting his instincts guide him, he started to thrust his hips up into her.
Bulma moaned while groping her milk tanks and meeting Gohan's upwards thrusts with her bouncing. It got better when she felt Gohan grab her bubble cheeks.
"Ah, yes! Fuck me! Fuck me, Gohan! Oh, you are so big!" Bulma cried out in rapture. All the years of no sex were being pounded right out of her.
"Ugh, Bulma! You're so tight! I never knew sex would feel so good!" Gohan grunted as he continued to thrust up into his students mother.
"That's because, ah, studying and experience are two different things! Oh, god! Hit me right there again, baby!" Bulma moaned as she felt her G-spot being stimulated.
Which Gohan kept hitting over and over again. He found the pleasure in Bulma's voice to be arousing. He then spotted her bouncing bosom.
Getting up into the sitting position, he took her right nipple into his mouth and started sucking the pink nub.
"Yes, Gohan! Suck my nipple, baby! My breasts are all yours!" Bulma cried while pushing his face further into her tit.
Gohan continued thrusting into his godmother's cunt for twenty minutes while still mauling the fleshy globe before switching to the other one.
This continued until he rolled them over into the missionary position. Gohan grunted as he resumed thrusting into Bulma even harder. Much to her pleasure.
The two soon came together in a kiss while still answering the call of the wild. The squeaking bed springs filled the room along with the sounds of skin slapping skin, moaning, and grunting.
The human and half-Saiyan swirled their tongues around each other while gazing into each other's eyes with lust and passion.
'I know I'm only doing this to continue my friends family line, but I never knew how handsome Gohan was. If we weren't in an era where we weren't being threatened by the Androids, he would be beating off girls with a stick.' Bulma thought in pleasure.
The luminous light of the moon filled the room. Revealing the two to be in the throes of carnal passion and lust.
Much later, Bulma was on her hands and knees with her face buried in the pillow and her ass in the air with Gohan slamming into her from behind.
While he no longer has his tail, the full moon's light had an effect on him. The half-Saiyan felt his primal side aroused from it's long slumber and had him go a bit more harder into the human female below him.
Bulma felt her eyes roll into the back of her head as she didn't know what has brought about this change in her godson, but she wasn't complaining as this was even more better than before.
She could feel her release was upon her while also feeling her young lover breathing harder as well as twitching around inside her.
No words of encouragement was needed as she could feel Gohan stopping in the least.
'Do it, Gohan! Put a baby into me! Use me to continue your family's line!' Bulma thought wantonly.
A few more thrusts later, Gohan threw his head back as he unloaded his sperm into his godmother's womb. Bulma let out a silent cry as her orgasm hit her like train. But the feel of Gohan's warm cock milk filling her made the experience even better.

Five gallon's of sperm was pumped into Bulma's womb. The blue haired beauty smiled while sighing in pleasure as she not only accomplished what she had primarily intended to do, but also felt years of no sex melt away.
The amount of half-Saiyan sperm was amazing. But then again it was no surprise that Gohan was so backed up.
But just as she was about to fade away into a pleasure filled slumber, Bulma felt herself being turned onto her back. She looked up and saw the primal look in Gohan's eyes.
With a savage growl, the son of Goku descended down onto his godmother and resumed pounding her into oblivion. All the while Bulma was unable to get him to stop so she could rest.
An hour later
Gohan was thrusting into Bulma while having her up against the wall back first. He didn't stop until he poured another five gallons of sperm into her.
Another hour later
Bulma was in the standing position with Gohan thrusting into her. She had trouble standing on one foot while her other leg was being held up. This continued until her overstuffed womb was filled with more of his white water.
Thirty minutes later
Gohan held Bulma up with both arms under her knees while still thrusting up into her. The black haired warrior and blue haired female was kissing until the former came inside her again.
Twenty minutes later
Gohan was on top of Bulma once more and was thrusting into her sore snatch until he distributed another helping of cock chowder into her one more time.
(Lemon End)
After being in multiple positions, Bulma was finally allowed to sleep as Gohan finally exhausted himself from pumping his thick and creamy fluids into her body.
She almost looked like she was 4 months pregnant. But with how much sperm she had inside her, it would be a surprise if she wasn't.
Inside Bulma's womb
Gohan's half-Saiyan sperm cells surrounded Bulma's eggs and continuously assaulted them until the broke through and fertilized them.
Epilogue
Bulma placed her hand on her pregnant belly as she watched her son disappear into the sky along with her the time machine she built and into the past so he could change their present. Gohan would've gone, but he was still recovering after their last encounter with the Androids.
End
Authors Note: In this story, Gohan survived his encounter with the Androids, but was injured in battle. And instead of giving away who Gohan will sleep with in the next chapter, I'll let you all decide.
