Chapter 10: Chapter 10: Between the Older Sister and the Girlfriend***
"Cough, I'm fine, really." He pretended to cough, thinking of an excuse, and said, "I just... must have stayed in the bath a little longer than usual..."
"I understand, be careful, don't stay in the bath too long, I've warned you before, right?" Her voice sounded understanding and worried.
On the other hand, what would she think if she knew the real reason his voice sounded strange was because his girlfriend was being impertinent, teasing his dick while he was on the call with her?
Covering the phone with his hand, he said softly, moving the phone away and leaning towards her: "Rei, stop teasing me, she'll end up noticing."
Looking at him, she thought for a moment before nodding: "Okay."
Sighing in relief, he removed his hand and continued talking to his sister.
While Hisashi was talking to his sister on speakerphone, he never took his eyes off Rei and saw her grabbing a hair tie. As she grabbed it, she started tying her hair into a high ponytail. So far so good...
However, it seemed that her mischievous side was stronger than herself. Rei crawled towards him as soon as she tied her hair, licking her now swollen, red, and plump lips after so many kisses, getting just a few centimeters away from his lips and the head of his dick.
Even hearing his sister ask, "Hisashi, I always come home on Saturday mornings, right?" he couldn't take his eyes off Rei.
Deep down, maybe he had some expectation for what was about to happen? After all, he never made a real effort to push her away...
The situation itself made it difficult for him to concentrate on the call while watching Rei reach his cock. With her small and adorable tongue, she licked the underside of the head up to the hole of the glans, swirling her tongue a bit around the hole and a bit around the head.
Taking a deep breath, trying not to make a loud sound, Hisashi only responded seconds after hearing his sister repeat the same question and ask if he was listening: "Y-Yes, I heard, and yes, I know."
"So..." She continued: "It looks like I'll be back a bit later that day, I'll need to stay a bit longer here in the city."
And she started explaining about a group project she needed to do, which was the reason for her delay.
While his sister continued talking on the phone, mentioning how there was an annoying girl in her group whom she regretted teaming up with, who kept talking all sorts of nonsense about her more than five boyfriends, etc...
Hisashi watched Rei licking his glans as if it were an ice cream. Sometimes, she looked very innocent, covering his glans with the foreskin, and her eyes shone with satisfaction. Soon after, she uncovered the glans and licked it again with her tongue...
'What kind of entertainment is this?' Hisashi didn't know whether to laugh or cry. But he couldn't say he totally disliked it...
"Hisashi! You can't be like someone like her!" Suddenly, his sister just blurted out these words for no apparent reason.
Hisashi was obviously confused, thinking: 'Where did all this come from?'
Even Rei stopped what she was doing, raising an eyebrow and looking at him dangerously.
"Of course, I wouldn't do something like that." He denied it, without even knowing what the hell she meant by that. He remembered she was talking about the girl in her group who had more than five boyfriends, but at some point, he just stopped listening and didn't recall what she said next.
But his answer might have been the right one because his sister said, satisfied: "That's good! Hehe, yes, yes, you certainly won't be like someone like her, right, right?"
Even though she seemed to partially believe him, at the same time, it seemed like she doubted his character. Did the original Hisashi do something that made her believe he was that kind of person?
Although he had his memories, Hisashi couldn't think of anything upon seeing the memories that could suggest that was the case...
"Mmm..." Hisashi let out a muffled sigh.
The reason was that, after getting used to her playing with the head of his dick, Rei didn't seem as satisfied just doing that. She leaned in again, wrapping her now wide-open little mouth around the smooth head of his dick.
Hisashi sighed once, then twice with the heat of her mouth as she gently sucked him.
Rei held his thick dick near the base and soon began pushing her lips up and down on his dick, taking more of his length into her lovely mouth with each thrust.
If he wasn't fully hard before, now he was as rigid as a rock, and Rei was struggling to take more than half of his big, thick dick into her mouth.
Hisashi could see Rei's swollen red lips stretching to accommodate his dick. Her lovely mouth was really tight around him, and he felt like he was in heaven.
"Hisashi?" His mind was brought back to the phone.
"Sorry, I got a bit distracted." He apologized.
"Seriously, are you really okay, Hisashi?" She sounded more worried than before: "You've been distracted since I called you. Did something happen?"
"About that..." Hisashi took a deep breath, thinking to himself as he felt the wonderful sensation of Rei eagerly sucking him, even better than when she did it for him before, being even better at it compared to the first time...
But he couldn't just say: 'Sorry, Tsuki-nee. Rei was being naughty and playing with my dick all this time... That's why I couldn't respond properly.'
"Actually, there's something I need to tell you, something that's been distracting me..." When he said that much, he saw Rei stop what she was doing, her seductive reddish-brown eyes widening.
Taking advantage of this opening, he continued: "There's something I need to talk to you about, but it has to be in person. But, it's not that urgent, we can talk tomorrow after you return."
"Ah, okay then." She replied, curious but not enough to make him say what it was over the phone: "In that case, I'll see you tomorrow."
"Yes, see you tomorrow." Hisashi said and held his breath once more to keep his voice from escaping, because Rei seemed to have gotten furious for some reason...
She lowered her head as much as she could, taking more than half of his cock into her mouth and throat, making small gagging sounds as she moved her head. Her brownish-orange ponytail swayed from side to side with the motion.
Hisashi didn't even hear what his sister said before ending the call because the heavenly sensation of having Rei's warm mouth taking more than half of his cock was intense. She went deep enough for him to feel his dick passing through her throat, stopping only when more than 15 cm of his cock were in her mouth.
Throwing the phone to the other side of the bed after confirming the call was ended and knowing that Rei heard everything since it was on speakerphone, he placed his hand on her head and growled softly: "You've been very naughty this whole time, haven't you? When did you become a bad girl who takes her boyfriend's dick while he's on a call with his sister?"
Without fully removing him from her mouth, Rei looked at him with her big reddish-brown eyes. At that moment, she looked so innocent, despite having her red lips wrapped around his hard cock.
Her cheeks flushed at his words, but she used her right to remain silent, mainly because her mouth was occupied and she seemed reluctant to take his cock out of her delicious mouth.
"Never mind." Seeing that she wasn't going to respond, Hisashi didn't insist.
After all, having such a stunning beauty sucking him, even if she had been a bit naughty, didn't bother him. Moreover, the sight of his cock disappearing into her small mouth while she looked at him made it even harder, and he could feel his orgasm approaching, knowing he wouldn't be able to hold back for much longer.
"Mmnn~" Hisashi moaned.
Rei, who could feel the change in him, grabbed his thick cock with both her small hands. Moving her mouth to have just the smooth head and a little more in her mouth, she began to pump his cock with her hands and move her tongue around the glans while maintaining eye contact with him, seeing that he was enjoying it and moaning loudly.
Hearing his moans, Rei felt they were so hot and sexy that she got wet and thought randomly: 'Who said men don't moan and that if they do, it's not sexy?'
She wanted to bring that person here and have them hear her boyfriend moan because of her... actually no, on second thought, she retracted what she 'said,' she preferred only that she could hear his sexy moans...
Coming back to herself, she felt the cock in her hands and mouth twitch and heard him say he was going to cum, so she closed her lips around the glans while continuing to pump his cock.
"Mhmm, God!" Hisashi seemed to be in heaven while she did this for him. Soon, he felt a strong surge of happiness as he ejaculated his jet of cum into her mouth, going deep and coating her tongue.
Rei's eyelids closed for a second when she received his bursts of cum, but she quickly opened her eyes and looked at him as he continued to spray his cum into her mouth.
Rei kept pumping his now sensitive cock with her hands firmly gripping it. With her tongue, she licked the head of his cock, even as it continued to shoot its final loads of cum into her willing mouth.
"Sigh... You're amazing, Rei." He caressed her head.
Feeling his touch on her head and hearing his words, Rei felt happy and proud of herself.
Rei could feel the sticky cum flowing down from inside her; it was warm, viscous, and incredibly addictive!
Swallowing nonstop, she could swear she had swallowed at least a liter of cum... Of course, it was just her imagination since this time it seemed he had cum much more than the first time she had taken him into her mouth...
When his cock finally stopped twitching in her mouth, Rei withdrew it, but not before sucking one last time with her lips closed around the glans and, with a loud pop, she released her lips.
Rei, who felt some sticky cum slip from her mouth, licked her lips and swallowed. However, inevitably, some slipped from her lips, running down her face and chin, looking incredibly naughty as she gazed at him while breathing hot breaths and her reddish-brown eyes shone with lust.
"Wow, damn, that was good." Hisashi said.
Sitting back on her knees before him, she smiled innocently, which didn't match all that she had done, and said with flushed cheeks: "I'm glad you liked it~♪"
Smiling back at her, Hisashi saw that she was dripping when he looked down. Soon, he threw himself at her, making her yelp in surprise, then he went down to her breasts, sucking them and moving down her belly while kissing all the way...
"Wait, I'm not ready to have you inside me again..." She said, closing her legs and pushing his head away, distancing him.
"Don't worry, Rei." Hisashi assured, looking into her eyes: "I'm not going to fuck you, but rather just use my tongue."
"That..." Thinking about his tongue, she choked and thought: 'If he only uses his tongue, then...'
After thinking for a bit, she nodded, giving her permission.
