"Were you just watching porn!?" shouts Kanna Shinozaki, barging into the room in a fit of anger. She's a coworker staying in the adjacent room. Spotting beer on the table, she immediately cheers, "Kanpai!!" livening up the night atmosphere. Right after, a furious "Boom!!" echoes from the room on the opposite side—a loud thud against the wall. "Crap… this hotel has super thin walls," we whisper, continuing our quiet toast. Gradually getting drunk, Kanna keeps drinking while venting about work frustrations, eventually passing out and falling asleep on my lap. Watching over her, I can't help but notice her top slipping with every toss and turn, her ample cleavage exposed, soft breasts tempting my hands. I resist at first, holding back—but just as I hesitate, she suddenly grabs my hand and whispers, "Go ahead… touch me already. You're making me impatient," guiding my hand into her cleavage, urging me to fondle her breasts. Giving in, I start kneading her tits, and she twitches in response, letting out soft moans. My restraint shatters. I dig my fingers into her fair skin and areolas, gripping and squeezing her soft, plump breasts over and over. Kanna's face flushes deeply. My cock hardens with arousal, and when I place it in her hand, she says, "Getting a rock-hard dick leaking pre-cum in my hand? That's turning me on…" Suddenly switching to an aggressive mode, she licks and teases my nipples, then eagerly takes my fully erect cock into her mouth, swirling her tongue to drive me wild. Then, using her large, soft breasts, she gives me an exquisite titty fuck. "I'm gonna take it now…" she says, straddling me in a face-to-face sitting position, impaling herself on my bare cock, riding me hard with intense thrusts, chasing orgasm after orgasm before I climax inside her with a creampie. Lost in pleasure, we forget to keep quiet. An illicit office romance consummated through raw, unprotected sex on a business trip.
