Hikari is my grade supervisor, and today's agenda is a site inspection for next year's school trip to Tokyo—just the two of us alone together. We've been having an affair for several months now, and every day after school she secretly visits my room, occasionally indulging in sex. Students see her as "strict" and "scary," but in reality, she's cute, shy, and absolutely loves sex. Her stunning beauty combined with her incredibly erotic nature makes her the perfect woman for me. Lately, I've genuinely come to think how lucky I am that she was assigned to this school. After casually drinking at an izakaya, we head to our reserved hotel. She joyfully admires the Tokyo night view, her innocent excitement making her even more irresistible. When she says, "Such a wonderful place... thank you so much," she suddenly becomes aggressive, whispering, "I want to lick you a lot too." Her perfectly shaped, massive tits are incredible. The moment she removes her bra, they softly sway, an insanely erotic sight. Kneeling down, she hungrily devours my cock, gently licking the tip at first—chup chup—then gradually taking it deep into her throat. Her devoted blowjob, using her tongue and lips to tease and entice, completely shatters my self-control. Unable to hold back, I immediately thrust inside her bare. Her pussy is already soaked and slippery. Her skilled hip movements are so intense I feel like I'll cum instantly. In cowgirl position, she slowly sinks down, then starts rhythmically thrusting her hips back and forth in small, precise motions, directly stimulating her cervix. Moaning, "Mmm... there... I love that spot..." she grinds her inner walls against me on her own. The glass-walled bathroom is pure temptation—her gorgeous tits pressed against the transparent glass, fully visible from outside. I wrap around her from behind, thrusting hard and deep in raw gonzo style. Reaching my limit, I push all the way in and creampie her. She seems to feel the hot spurts hitting her cervix, innocently giggling, "You came so much~." After a short rest, round two begins—she surprises me with sexy lingerie she brought specially for tonight. Seeing her, usually dressed in suits or gym wear, in such erotic underwear, her flawless body completely exposed, leaves no room for resistance. I can't hold back—I pin her down and pound into her relentlessly, thrusting over and over with fierce intensity, repeatedly slamming into the deepest part of her womb. It was truly the most amazing night.
