As the bout of pleasure was transferred to me when Rae started stroking my dick, my mouth bit onto Kana's bra, lifting it up to give me access to her bountiful marshmallowy softness.
While I started kissing and savoring Kana's assets, the two started a conversation among themselves.
"A-am I doing this right, Kana-senpai?" A bit flustered because it's her first time seeing and holding a dick in her hand, Rae asked for Kana's advice.
"Hhng… Yes, you're doing it well enough. Just continue stroking it until it stands upright. That's when you will know Ruki is fully turned on to us." Amidst her silent moan and her tightening fingers on my hair, Kana answered.
As Rae followed that advice by gripping my cock tight before moving it up and down, my lips and tongue slowly moved from the middle of Kana's chest to one of her pinkish nipples.
Tasting her sweetness after a few days of not being with her became another stimulant for both of us to enjoy this time together.
In time, Kana stopped patting my head and instead hugged it tightly as she tried to press my head further into her softness.
Alternating between her nipples and playing with them using my fingers and my tongue, Kana's sweet moans gradually filled the room.
And because of that, Rae who's intently watching my dick while she's playing with it started breathing heavily on it.
From the side of my eye, I saw Rae looking up at me to see my reaction. When she noticed how I was focusing on Kana, she bit her lips as she slowly drew her face closer to my cock.
"Mirae, use your tongue on its head. Haahhn… Ruki will feel it better if you focus on it while you continue stroking its length."
Acting as a Mentor for the knowledge girl, Kana instructed Rae who seemed so lost on what to do.
Looking at her lips that were about to kiss the tip of my cock, I paused at what I was doing to let her know that I was also watching her.
Even if I became engrossed with Kana, there's no way I would forget that she's also here with us. Moreover, she's doing her best to return the favor I did for her back at that Equipment Storage room.
"Rae, you're doing it well, I won't be that hard if not for you. But remember, don't push yourself if you can't."
Upon hearing that, she immediately shook her head and the glasses adorning her face somewhat flashed a glint of her determination.
Soon after that, she put her face closer to my cock while her tongue slowly peeked out, stretching itself to lick the tip.
At first, she was only trying to taste it but as time passed, her tongue's movement gradually grew wide enough for her to not only focus on the tip but the entirety of the head. Licking every spot wet including the frenulum with her saliva, Rae eventually opened her mouth to take it in inside.
Although clumsy, seeing the girl doing her best for the first time was a huge turn-on for me.
I reached my hand and placed it on top of her head before I intimately caressed it.
When she felt my hand, Rae lifted her gaze to meet mine and gave me her beautiful smile. With that kind of picture with my cock next to her, I somehow felt that it was a shame not to snap a photo of it.
Well, instead of that, I burned it in my memory. After this day, I could recall it anytime.
As I felt the warmth and moist feeling when my cock entered her mouth, I turned to Kana and pulled her head down for a kiss while my hand went down and invaded her skirt.
Tracing my fingers on her slit, I parted the cloth covering her private part to give me access to her sacred place.
Without breaking our kiss off, I began rubbing her slit with my fingers before focusing on her clit.
As soon as I pinch that part of hers, Kana moaned loudly, startling Rae.
However, when she looked up and saw that we're back at locking our lips together, Rae went back to what she was doing, sucking the head and stroking my cock at a faster pace than earlier.
Being pleasured by one and pleasuring the other, our situation eventually reached the point where both Kana and I were about to cum.
Rae did great from using her mouth and tongue that no place became left untouched by her mouth. Due to that, I also became eager at romancing Kana through the use of my fingers.
In time, Kana slumped her body to my chest as she's trying to focus on the sensation that I was bringing her.
As we both moaned out from the pleasure, my finger inside Kana felt how she almost twisted her body from the pleasure. At the same time as that, although I warned Rae about it, she held my cock inside her mouth to receive everything I shot out.
As Kana erotically gasped for her lost breath, Rae, whose cheeks became somewhat bloated from my semen, gulped it down before standing up from there to sit next to me.
"It tasted weird but I couldn't just waste it, you did the same for me back then," Rae whispered in my ear before leaning her head on my shoulder. There's an erotic smile on her face that was further accentuated by how she adoringly stared at me.
Upon seeing that, I couldn't help but lament how I corrupted this innocent girl. Back then, she's just focusing on gaining more knowledge but at this point, although she's still doing the same by gaining knowledge for this sort of thing, her expression and the way she looked at me were now too unbearable. I was already deliberating if I should take her this time, in this room.
"I'm sorry for corrupting you to this extent." I circled my arm around her back and placed it on her shoulder.
When she heard those words from me, her gentle gaze instantly turned into a glare as her moist lips pouted.
"If you say sorry again, I'll bite that off next time. You know that's not the case. I was perverted like you and only for you."
"W-what are you two talking about?"
Kana, who had just recovered, wondered after seeing how we were staring at each other.
"I'm scolding him, Kana-senpai. He keeps saying sorry again."
With a rare smirk from the knowledge girl, she tried garnering Kana's support.
Blinking her eyes as she alternated her gaze between the two of us, a somewhat impish smile bloomed from Kana's lips.
"I see. We have to punish him. Rae, you still haven't had your first time, right? You can watch us and learn."
As soon as her words ended, Kana stood up and went to her favorite position, straddling me.
Curious about what we will do, Rae was eventually enlightened when Kana adjusted herself on top of my dick and lifted her skirt, showing that wet part of hers wherein a trickle of her love juice was flowing down from the side of her legs.
In front of Rae's eyes, Kana grabbed my still erect cock and aimed it at her sacred hole. As Kana lowered her hips bit by bit, Rae watched on as my length slowly entered Kana's insides.
"Hahh… Ruki." Kana instantly moaned as soon as my cock fully entered her.
This cute and shy senpai, which part is the punishment here? Not only Rae, but I also corrupted this girl to this extent. This should be the second time wherein we had an audience.
But unlike Otsuka-senpai, Rae wasn't an ordinary audience.
As Kana slowly moved her hips on top of me to let me start grinding her with my cock, Rae watched intently first before grabbing my head to have me kiss her.
As she didn't want to be left out when Kana and I began having sex, Rae not only took my lips for her but also my hand to slip it inside her skirt, wanting the same treatment I gave to Kana earlier.
Although I did what she wanted, that was proven not enough for her.
After a few minutes of watching Kana move her hips up and down my cock, Rae pulled on my arm and my body.
Understanding her intention, I grabbed onto Kana's buttocks to keep her in place before I gradually laid down the sofa.
With an erotic smile on her lips, Rae climbed up, lifted her skirt and sat on my face with that part of hers directly touching my lips.
In this kind of position, the room soon began to be filled by the two girls' sweet and lust-inducing moans.
Below them, I eagerly used my mouth, tongue as well as hips to pleasure the two women until we all reached the climax at the same time.
In the end, the Kana slumped down onto my body before squeezing herself to my right side while Rae placed herself to my left, using my arm to prevent her from falling down the floor.
If we continue using this room, I guess it won't be long before this sofa breaks down on us.
Ah, well, that's not important, if it breaks, we'll just bring a new one or perhaps a proper bed for a change. As long as this room continued to be empty… This is the most ideal place to bring my girls.
I just don't know if the club next door can hear us inside. Given that no one's knocking on the door to tell us to keep quiet then I guess it's still safe.
