Quite as she can be, Kasumi is sneaking through a warehouse while carrying a pink-haired boy named Arthur Farron on her back. Since he's light and sleeping, Kasumi's stealth is not hindered. "Kidnapping and experimenting on a mother's child, how could they?!" Kasumi thought angrily. She had to stop for a moment because guards were coming her way.
"Find the test subjects, they haven't gotten far!" one of the guards said.
Kasumi only moved once she knew for sure no more guards were heading her way.
She got out of the warehouse and once she made it to a safe enough distance, pulled out a small device and pressed the button on it. As soon as she did, the warehouse blew up. Destroying the building and killing everyone inside. Kasumi didn't care because of all the horrible things those people did in that warehouse.
Kasumi didn't say long to admire the destruction she did because she wants to check on what they did to the boy he saved. She also made sure to send a message to the boy's mother, Lightning Farron, that her son is safe. The mother quickly responded with a heartfelt thank you and that both she and Ayane had rescued the other children.
As Kasumi checks on Arthur, he seems to be healthy but she does discover one thing wrong about him, his dick is throbbing and rock hard. What is worrying about this is Arthur has been like this for two and a half hours and Kasumi heard being erect for more than four hours is bad. So with no other choice, Kasumi open's Arthur's pants who is still sleeping.
"Oh my!" Kasumi gasped "He's big for his age!" Kasumi takes a deep breath and wraps her hand around Arthur's shaft. Young Arthur starts to moan when Kasumi starts to stroke his shaft.
Arthur finally wakes up, "Kasumi? What are you doing?" he asked with a groggy voice.
"Oh! Um, you're poisoned and I'm trying to heal you," Kasumi said nervously.
"I thought the stuff those jerks injected me was poison," Arthur then moans, "Your hand feels good for some reason,"
"That means my treatment is doing its thing," Kasumi smiles, "Did you hear what those mean men said when they were injecting you?" Kasumi asked.
Arthur shrugs, "Something about being irresistible and someone being hooked and being like orcs?"
"I see," Kasumi then thought, "So that's what they are doing," she then looks at Arthur's large cock and can tell that her hand job alone is not going to make him cum, "I'm going to do something different. Just close your eyes and relax," Kasumi said softly.
Arthur nods, "Okay," he does what Kasumi asked because knows and trusts Kasumi because she was his babysitter during the time she was pretending to be a high school student and developed a strong bond.
Taking another deep breath, Kasumi opens her mouth and wraps her soft lips around Arthur's cock. Immediately as her tongue touched his shaft, her whole body started to heat up. Confirming Kasumi's theory. Those scumbags were kidnapping boys Arthur's age and using them to find a way to make a human's dick irresistible like an orc's.
After many failures, they succeed with Arthur. Evident by how hungrily Kasumi is sucking off Arthur and rubbing her pussy vigorously and she got started. Even though the leather of her outfit, Kasumi can tell how wet she is.
The drugs they injected him with didn't change the size of his dick, he was naturally well hung, it only gave his manhood aphrodisiac-like properties. That didn't bother Kasumi because Arthur's a sweet and good boy, he deserves something nice for the horrid treatment he went through. Also, Arthur is both cute and handsome.
"K-Kasumi!" Arthur moans, "I feel…WEIRD!" his hips bucks and shoots his cum in Kasumi's mouth. This catches her off guard but regains her composure and drinks Arthur's seed. It too has aphrodisiac-like properties, resulting in Kasumi's sexual desires to increase even more. Thanks to her ninja training, she still has control of herself, for now.
Opening his eyes, Arthur sees Kasumi pulling his dick out of her mouth and his cum on her lips. "Why is my pee white?" Arthur asked.
"It's not pee, it's cum. It's what comes out of a boy's penis when he feels really good," Kasumi explains. "Normally, once a boy cums his penis gets soft and limp but you…" Kasumi smiles and gently strokes Arthur's dick, making him moan again, "Are still hard~ Looks like I have to do something else~" Kasumi purrs and licks Arthur's cum off her lips.
Young Arthur is not sure why but seeing Kasumi doing that made him feel excited, "What do you have in mind?" Arthur asked.
Kasumi smiles and repositions herself so her large breasts are parallel with Arthur's cock. "I know you've been looking at my chest a lot lately," Arthur is about to say something but Kasumi stops him by putting a finger on his lips, "It's okay Arthur, it's normal for a boy your age to look," Kasumi holds her breasts and wraps them around Arthur's cock and starts to move her breasts up and while pressing them together. She didn't have to pull her breasts out of her black leather leotard because the valley between her breasts is already exposed, "So? How do my breasts feel?"
"Soft!" Arthur moans and grips the bedsheets tightly, "And good!"
"Then I'll keep going~" Kasumi purred, "And remember Arthur, relax~"
"Okay," Arthur nods and closes his eyes. He lets himself enjoy the sensation of Kasumi's breasts rubbing against every inch of his cock. He's not sure which one feels better, Kasumi's mouth or her breasts. But he pushes that thought aside and enjoys the moment.
Both Arthur's cum and Kasumi's saliva worked as lube so Kasumi's breasts could move smoothly.
Kasumi moans with Arthur because she's getting pleasure from titty fucking him. Her hardened nipples are rubbing against the soft white cloth under her leotard, sweat building up and her pussy is aching for Arthur's cock.
Biting her lip, Kasumi fought the urge to rip a hole on her leotard and ride Arthur, "He's going to cum soon! I can feel him throbbing between my breasts! Just a little while longer!" Kasumi thought and moves her breasts a bit faster.
"Kasumi! I'm doing that cum thing again!" Arthur moans loudly and shoots his second load of cum. He lets out a lot more than before. His cum covered Kasumi's breasts and a bit of her face.
"You let out so much!" Kasumi gasps happily.
Arthur opens his eyes and sees Kasumi licking his cum off her breasts and face. The sight caused Arthur's cock to twitch. Something that Kasumi noticed, "It looks like you still go for round three~" Kasumi smiled. She stands up and moves the lower part of her leotard to the side, letting her love juices drip down her thighs, she then pulls her breasts out of her leotard. Showing young Arthur her bare breasts. His eyes locked onto her nipples and his mouth felt dry.
"What I'm going to do next is going to make you a man~," Kasumi said sexually and slowly crawls on top of Arthur. She grabs and holds his dick still and rubs her wet slit against the tip of Arthur's cock.
"W-What do you mean?" Arthur asked while moaning.
"It's better if I showed you~" Kasumi smiles and slowly (she didn't have sex in long while) lowers her hips. Both of them moan at the same time as Arthur's cock enters deep inside Kasumi's pussy.
"I'm inside you!" Arthur moans.
"Yes, you are!" Kasumi moans. She leans forward and puts her hand over Arthur's head. Her large breasts hang over Arthur's face. Her breasts swings up and down as Kasumi moved her hips, "You're so big! Arthur!" Kasumi moans, "The biggest by far!" she suddenly moans loudly when Arthur starts sucking and rubbing her nipples.
He groans when feeling Kasumi's pussy tighten, "Her insides feel warm, wet but good!" Arthur thought.
"No milk is going to come out but keep sucking anyways~" Kasumi moans. She closes her eyes and tilts her head back, "I can't believe I'm having sex with a young boy but his cock feels so good~," Kasumi thought lustfully. Her hips keep moving faster and faster until the bed they're on starts to squeak.
Kasumi's hips stop from time to time because she was cumming but due to how much lust is overwhelming her, starts to move her hips again.
After a while, Kasumi and Arthur changed positions, both are laying on their side, Arthur is behind Kasumi, holding up her left leg and is reaching around to grab Kasumi's breast, Kasumi meanwhile has an arm around Arthur's shoulder and is gripping the bedsheet, "Oh yeah! Thrust your hips just like that!" Kasumi moans, "I'm so glad Claire gave Arthur so much stamina and strength training~," Kasumi thought.
They stayed in this position until Arthur cums for the third time. Kasumi cums with him, mixing her juices and his cum. Kasumi can tell Arthur has finally reached his limit because she can feel his dick getting soft.
Changing positions one more time, Kasumi holds Arthur in her arms, "What we just did is called sex, it's something you do with a person who you love the most," Kasumi said softly.
"Well, I love you," Arthur said blushing.
Kasumi smiles warmly "I love you too," she gently touches his face and kisses him on the lips.
The next day, Kasumi nervously tells Claire that she had sex with her son. Claire wasn't mad, she's happy, "I'm glad my son's first time was with someone wonderful like you," hearing that puts Kasumi at ease. Claire continues, "The poison my son had is gone thanks to your treatment but there are still some lingering effects,"
"Like what?" Kasumi asked.
"Not sure, from what Lisa said, it's nothing but she's doing a follow-up to make sure," Claire said then puts a hand on Kasumi's shoulder, "So in the meantime, keep giving my son your special treatment and don't worry, I asked a few ladies to help you out and give you a chance to recover," Claire smiles.
Kasumi blushes madly, "WHAT?!"
