"That's it... squeeze your hands together. Can you feel the warmth? This is the proof of Ito-sensei's excitement..."
Before Shinju could adapt to the shame, Marin began her lesson. Rin sat on the black leather sofa, Shinju knelt before him, and Marin stood behind her, holding Shinju's stiff hands to teach her how to serve him.
It took a while for Shinju's mind to return from the blank void. "See? Isn't it because of your body that he's like this? So stop saying you're ugly. Go on, try it yourself."
Marin slowly let go. Instinctively, Shinju followed the movements Marin had shown her.
Gather, squeeze, release.
Though the movements were simple and the service was green, combined with the softness of her massive breasts, it drove Rin wild.
"This sticky fluid is also proof of excitement. Shinju, you can spit some saliva on it... yes, just like that~"
Following Marin's instructions, Shinju gathered some spit and let it slide onto her breasts. With the lubrication, every movement she made produced a wet, squelching sound.
While Marin taught and Shinju served, Rin wasn't idle either. His hands gripped her nipples, twisting them half a turn with a mischievous tug.
"Ugh!!!" A soft cry escaped her. The unprecedented tingle made her legs tremble so much she nearly slumped to the floor, but she steadied herself just in time.
As she endured the tingling, her movements caused even more friction, sending shocks like electricity straight to her brain and then down to her crotch. Her legs instinctively pressed together, rubbing against each other.
The strange sensation confused her. Why does it feel so different when the President touches me compared to when I touch myself in the bath?
Unlike her sister, Shinju had no experience with "self-pleasure." Sajuna would occasionally "generate electricity" at home, but Shinju had only ever felt similar sensations when clutching a duvet or a body pillow. It was weird, but... it felt so good.
The instinct for pleasure caused her to speed up her movements unconsciously. The friction between her thighs intensified.
What... what is this feeling? It feels like... like something is coming!!!!
A bit... a bit faster, a bit harder...
Like a student daydreaming in class who thinks they're being subtle, Shinju's small movements were obvious to those watching. Marin, standing behind her, smirked and winked at Rin. Then...
"Ah!!!" An exclamation burst from Shinju's lips as her hands stopped. "Marin... what... what are you doing?"
While Shinju was lost in pleasure, Marin had reached around and slid her hand between her buttocks, her slender fingers easily finding the gap between her pressed-together thighs. Even through the fabric of her panties, the experienced Marin could feel the dampness.
"You can't stop, Shinju-chan. You have to keep going until Ito-sensei comes~"
In her confusion, Shinju resumed her movements. The tingle from her clit, now magnified by Marin's finger through the fabric, was something she had never experienced.
Moeha, sitting next to Rin, also pressed her legs together tightly. Her heart was pounding—not because she liked Shinju, but because... the idea of "staining" a pure girl white was just too good!!!!
Even when they were outside, Moeha had pegged Shinju as the soft type who wouldn't speak up even if bullied. So cute! Though Moeha loved bullying girls in her heart, she never did it at school; in fact, she often helped those who were bullied. But now...
I'm glad I came. Staying with Big Brother lets me see cute girls being bullied and trained~ Seeing a pure girl being corrupted... it's amazing!
Rin glanced at the excited Moeha. She seems to really enjoy this... is she a lesbian? In his past life's memories, Moeha wasn't a major character. He only vaguely remembered her being "Pink on the outside, Black on the inside." He didn't recall her having lesbian interests.
However, she was different from Hinata or Saya, who were true lesbians. Unless she had a cuckold fetish like them, she wouldn't have pushed his ass during the party. While she liked cute girls, her orientation seemed normal—more like Sagiri, who shouted about wanting to see cute girls' panties but still liked men.
And judging by how hard she pushed him when her sister Chika was being fucked at the hotel, her tastes were quite heavy. He'd have to find a chance to test her. But not today.
Rin turned his focus back to Shinju. She was visibly shaking now. Her crotch was soaked from Marin's finger, and her nipples were rock hard. To endure the pleasure flooding her lower abdomen, she had closed her eyes tight, her hands mechanically squeezing her breasts around his cock.
The technique was crude and mechanical, making it a bit difficult for Rin to finish. Seeing that Shinju was at her limit, Rin let go of her nipples and grabbed her hands, guiding them in his own rhythm while thrusting his hips slightly.
With her head lowered, his cock poked Shinju's face repeatedly. From her pink lips to her cheeks and the bridge of her nose, she was getting covered in pre-cum. Marin watched Rin, timing her finger movements with his thrusts.
"Ah... ugh!!!!"
Shinju felt a sudden rush of heat as she gasped. By the time she realized what was happening and closed her mouth, it was too late. Not just her mouth, but her entire face was stained with Rin's color.
Seeing Shinju's messy state, Moeha's legs clamped shut, and her toes curled. To be honest, just watching her made me cum a little.
Her face was stained, and even her long eyelashes and the corners of her eyes were painted with Rin's seed. A dazed Shinju slumped back into Marin's arms.
Marin, her eyes full of lust, smeared the wetness from her fingers onto Shinju's face. She wiped a bit of grime from the corner of Shinju's mouth and then pried open her neat teeth.
"This is the proof of Shinju-chan's charm~"
