Goten is training with Trunks, while Bura decides to watch them, 'I like it when Goten visits us. He's so cute!' As she looked at Goten her body grew hit for a second and she thought, 'He's so cute!'
As they fought, Trunks sent an attack at Goten but missed and was going to hit Bulla but flew quickly and picked her up, saving her.
Trunks quickly flew down and asked, "Are you ok?" Bulla patted her clothes and said, "Yes, I'm fine." But then she kicked him in the balls making him fall to his knees, she then kissed Goten on the cheek, "Thank you!" Before walking away.
Goten touched his cheek and asked, "What's going on? I don't get it, why did she do that?" Trunks who was still holding his crotch moans out, "Nghh! It's because she likes you a lot. Nmgh! Aagh! She's always watching you, I have even heard her say that she loves you. God, it hurts so much! Ngh!" Hearing that Goten walked off to see Bulla who was blushing from kissing him, "Bulls can I have a word with you?" Bulla stops moving but doesn't turn to look at him as he rubs the back of his head, "About what happened a moment ago, I want to tell you… Was like a dream becoming real, because I like you!" Goten bows his head to his blushing face, Bulla moves to him and kisses him on the lips which he returns but they stop when she pulls back.
"I felt something really hard down here!" Bulla says as she moves a hand to his crotch making Goten moan, "Is it what I think it is?" She asks looking into Goten's eyes who shakes his head but Bulla pulls his belt while saying, "I want to see it!" This reveals a full adult cock attached to the young Half Saiyan's body, "Wow! It's the first time I see one of this way!" It was half hard and when she grabbed hold of it she could feel a 'heartbeat' in it, but now it started to grow, "Waah! It's growing even more!" Bulla then started to smell it, "Now it looks much better! And I like its perverted smell!"
Bulla started to lick it a couple of times, getting Goten to moan her name, "Ahhh! I Couldn't resist licking it! It tastes funny, but I like it! I want to keep licking it…" As she places her mouth around the tip she thinks to herself, 'Finally I have it in my hands!' And as slowly as she makes her way to the base, 'It's all mine now, there's no turning back!' She then pulled back and forth quickly until she had covered the whole thing in spit before pulling off, "Are you enjoying this?" Bulla asked Goten rubbing her blushed red face against his cock, "Feels good." Was all he could say before Bulla had pulled him into a bush and removing her clothes, "Do you like what you're seeing?" She said covering her chest getting a nod from him with made her smile before she pushed Goten onto his back and got onto him with her pussy above his face and her face at his crotch.
As Bulla started to lick Goten cock she noticed that he wasn't moving, What are you waiting for? Lick me!" As soon as Goten's tongue touches her she falls back and screams, "It feels really good!" As she got used to the pleasure Bulla moved forward and went back to sucking Goten off. At this moment they had no clue that Trunks was outside the bush looking for them, "Where would Bulla and Goten be?" He says to himself before hearing moans and looks into the bush only to go wide eyed, 'SHIT!' He stands there with blood coming out his nose before pulling his cock out and rubbing it
Back to the two Bulla was feeling enter and better as she thinks , 'This is driving me crazy!' But Goten was close to cumming but didn't get to tell Bulla before shooting it into her mouth who pulled back sitting on his face and moaned, "Mmmm! Tastes good!" As Goten was still eating her out, 'This pleasure feeling is getting stronger! I can't stop! Having his cum in my mouth gets me hot!' Her body felt like it was on fire and she had to scream and release it all, "Nnnngh! I cannot resist anymore! Omg! I'M CUMMING! AAAAH!" As she cum she went super Saiyan for the first time which everyone felt, her father and Goku who were training stopped and turned towards them, Krillin who was fucking 18 freezes as he was about to cum inside her, and Trunks who was watching kept masturbating, 'Bulla transformed into Super Saiyan, I didn't expect that!'
"That was amazing! I've never felt something so intense!" Bulla moaned as she drooled out her mouth "Now I want you inside me, let's do it!" Goten then tells her about her being super, so Bulla flips over and lays face to face on Goten's chest, "Go Super Saiyan." He quickly went Super as Bulla smiled before she took Goten into her pussy, getting her to cry, "It's inside me I will always cherish this moment, our first time!" She then starts bouncing up and down and Goten looks at her, "Are you ОК?" Bulla nodded as she slowed down until she got her rhythm, when she did she sat up straight with her hands behind her head and legs apart, "That's it! YES! Tee-hee! I like this!!!" But soon the pleasure was too much and she grabbed her head as one finally thrust down had them cumming together before Bulla laid her head onto Goten's.
"Wow! This was amazing! It felt so good just as I imagined it. I'm very pleased! I hope we can repeat this soon!" Bulla says as she rubs Goten's chest but he says, "I'm still not satisfied, though." This made Bulla look down at his cock with wide eyes, "Woah! It's still big!" With a smirk at Goten, "OK! It's time to try something else..." Bulla got onto all fours and pointed at her asshole, "Put it in here!" Goten went right to fucking her hole getting Bulla scream in pain but she hid it into her arm, as he started to thrust harder he gave her ass a smack getting a moan of pleasure, he repeated this for over half an hour, "You filled my ass, it was great!!" A none super Bulla moaned out as she laid next to Goten as they fell asleep in their 'hidden' bush as they both say, "I'll never forget this day." Before making out not noticing that Trunk's had cum onto the ground between them, "I'll pretend that nothing happened in here." He says as he walks away with his hands on his head.
Many months later the adult family members of Bulla and Goten were in a room talking over her, "I cannot believe this, their bodies haven't even reached maturity!" Bulma shouted having seen her younger daughter's body, her shout gets a cough from Goku, ChiChi, and Videl as they knew this was possible as Vegeta had told them after asking him about Saiyans, "Bulma, I told everyone this could happen, when Bulla was born." Vegeta said as he entered the room, "When saiyan females fall in love, they become able to have kids like any adult would." He then looks towards a room before rubbing his, "They will try anything to make that happen, primarily they will try to have sex with the man of their affections, and when they succeed in doing it, it's almost guaranteed they will get pregnant." Inside the room he was looking at was Goten laying on his back naked with a very pregnant Bulla reverse cowgirl riding him as she begged for more.
