This time, the older sister we have here is a rare type who's never experienced piss drinking before. But the girls who come to shoot are always sincere, honest, and give their all. Although we were worried whether she'd really keep her promise—since she doesn't get easily flustered by small things—she ultimately kept her word completely, gulping down every last drop of the copious piss I'd held back right into her mouth. Since it's her first time, her mixed expressions of shock and regret are definitely a highlight. So let's start recording with our usual interview! She mentioned feeling lonely lately due to not having a boyfriend, and since drinking piss was completely new to her, she looked like she might burst into tears at any moment. Saying she didn't want to spill on her clothes, we stripped her completely naked just 15 minutes after meeting. Her small, pink nipples peeking from her pink bra instantly got my cock hard. Taking off her lower clothes revealed her slender, attractive legs. Wanting a good look at her most intimate parts, we had her spread into a wide M shape—her embarrassed expression was adorable. We also got close-ups of her anus before fully observing her entire female body. Now, finally, her first piss drinking experience. I poured the full load of yellow piss I'd been holding straight into her mouth, which she opened wide for me. The filthy yellow liquid pooling in her cute mouth, mixed with pre-cum and thicker in consistency, was even dirtier—gulp…! (Turn up the volume here—you can clearly hear it.) Be sure to watch her genuine reactions in the main video. For the second round, we used a fixed wide-angle camera shot. Since my cock was hard, it was harder to release, so only pre-cum went into her mouth this time (lol). Let's try again! This time, a strong stream hitting the back of her throat! For the third attempt, she took my cock into her mouth and drank continuously. Sucking my erect cock like a blowjob, her mouth became my personal urinal. Enjoy the loud gulping sounds and the movement of her throat! Even as she says, "It's disgusting… I feel like throwing up…" the challenge continues. The fourth round has her drinking from a glass. We filmed in one continuous shot as the bright yellow male piss flowed from my cock into her stomach. She bravely chugged down more than half a large glass—gulp, gulp, gulp, gulp—giving it her absolute all. (You can hear it perfectly even without turning up the volume lol.) Watch it over and over again! Next, she keeps my cock in her mouth while swallowing every last drop—piss flowing directly from my cock into her stomach. It's so damn hot I get excited just watching it…! She's gulping it down like post-workout sports drink—definitely something you need to see ☆ Finally, the last piss drinking scene takes place in the bathroom. I keep her mouth open, making her drink nonstop since she promised to finish it all. Her expression grows increasingly pained as the endless stream continues. I'm having so much fun pissing that I don't stop, releasing without pause—all of it straight into her mouth, deep into her throat. And finally, the ultimate climax: I push my cock deep into her mouth as she becomes the world's most pleasurable toilet, filling her with a massive load of piss. I emptied my entire bladder, pouring every drop into her body! (Afterword: She said she never wants to do this again! So this is the only place you'll ever see this!) She kept saying she felt like throwing up—but still finished every drop with satisfaction! Thank you, big sister!! Now that my cock feels refreshed, let's make it even more refreshed (lol). Since she hasn't had sex in a long time due to having no boyfriend, I playfully tease her slightly small breasts while we make out. Seems she's getting turned on—she asks me to lick her pussy, so I happily oblige. She twitches and makes such pleasurable expressions (a total contrast to earlier piss drinking lol). I'm so turned on I'm rock hard, so right there on the sofa, this man and woman who just met fuse together. I slowly sink my cock into her soft, warm depths. Since we're sitting on the sofa, we can both clearly see where we're connected. After enjoying ourselves on the sofa, we move straight to the bed. We have sex while chatting, hold each other tightly, endlessly suck her small, cute nipples, switch to doggystyle while still connected, thrust deeply and intensely… It's a very natural, intimate sex scene—kind of embarrassing but real. Finally, I finish by blasting her with a generous load of cum!! ※ Full face visible in main video
