Seiji quickly headed upstairs, his head buzzing like a fully charged phone. Never in his life had he considered being hugged, kissed—or more—by his stepmom.
More??
Was it really possible? Was it within the power of the amulet for him to do more with Haruko?
Sure, she was nice to him, and seemed like a decent wife, able to keep Jun afloat, not letting him completely disappear into his phone. But more? With Seiji?
Then he heard footsteps behind him. He turned just in time to see Yumi on her way to her room, totally oblivious. He waved and immediately jogged over to her.
"What is it, Seiji?" Yumi asked, looking surprised.
For a second, they just stared at each other, the only sound the soft hum of the hallway lights.
Then, without a word, Yumi just walked into her room, leaving the door open behind her. Seiji followed, his eyes glued to the way she moved. He was totally revved up after the encounter with his stepmom.
He closed the door behind him and pulled Yumi closer.
"You're too sexy," he said, sounding almost smooth and confident. "I can't stop thinking about it."
"Shh," she whispered. "You can't let the parents hear you."
Seiji never liked how she used the word "parents" when talking about his dad and stepmother. Haruko wasn't his mother, and he was never going to treat her as one of his parents. She was his father's second wife, someone who happened to live in the same house – but she wasn't his parent.
Still, he lowered his voice, while his hand slid up Yumi's body: "I want to see your breasts again."
"That's enough for one day, Seiji," Yumi whispered, meekly pushing him away.
"No," replied Seiji, getting hold of one of her breasts.
Yumi gasped from discomfort and awkwardly landed on a chair. "Auch," she muttered. "She just bit me when feeding."
Yumi's hand brushed Seiji's cock, and her demeanor quickly changed.
Seiji finally realized that the amulet must have given his cock the magic powers his grandfather was hinting at. Who would've thought it'd be so simple? The source of his power was his own penis! No wonder he had stared at it so many times in the past – it was clearly special.
Yumi squeezed his cock through his pants, not willing to let go.
"Mmm, it's so hard again," she murmured dreamily, suddenly all limp. "Let me see."
She pulled Seiji's pants down, smiling at what she discovered. Seiji's engorged cock stood right before her eyes in all its heated glory. It was bright red, with veins pulsing around the outside.
"Wow, it must be really painful," she uttered. "I must help you."
Wrapping her fingers around it, Yumi began to jerk Seiji off.
"Ah, sis," he whispered. "I want to rub it against your boobs again."
Yumi shook her head. "They're not comfortable at the moment," she said, gazing at Seiji's cock with obvious desire.
"But I want it," Seiji insisted.
"Quiet!" Yumi whispered and suddenly took him in her mouth.
Seiji moaned involuntarily from the strong sensation. Yumi's mouth was warm and wet, and her tongue was sliding around his shaft with an incredible sweetness.
"Sis…" Seiji muttered. "Fuck! That's awesome."
With a proud smile, Yumi began to move her head, sucking and licking Seiji's cock, her hand jerking the base of his shaft.
The feeling was almost too much to bear, and Seiji grabbed Yumi's head to push himself deeper. Yumi hummed something, but he couldn't stop.
Her mouth continued to move, slurping sounds of her sucking driving Seiji crazy.
"Yumi…" he panted. "You mouth… is…"
He then lost his train of thought. In any case, her sucking was indescribable.
Soon, Seiji was over the edge. Without warning, his cum started shooting into Yumi's mouth, as he held her head in place, his fingers tightening around her hair.
Seiji moaned loudly, his legs shaking. He was over the moon as Yumi's tongue brushed the underside of his cock while he shot the last load deep into her throat.
The sensation of release was so intense that stars and circles floated inside his eyes. It was like he was flying somewhere out in space.
Gradually, he released his grip on Yumi's head, and she let his cock slip out, her mouth closing as she swallowed.
"Your milk tastes good," Yumi murmured. "But I think mine is better."
Seiji could barely catch his breath. "Your milk is great, sis," he said finally.
Yumi smiled and pulled his pants back up.
"Now go back to your room before anyone notices," she whispered loudly.
"Okay," Seiji stuttered. At the door, he stopped and looked back at Yumi, who was happily licking her lips. "Thanks, sis."
