This time, the Shinjuku Koyuen girl is an ultra, ultra busty beauty—K-cup!! And her bust measures a staggering 116cm, way over 1 meter!? I've met countless big-breasted girls before, but this size is completely beyond standard! ...Though I've been talking about her breasts the whole time (my bad). This busty girl's name is Sora (works at a girls' bar). Even when she's clothed, it's obvious, but seeing her in person is overwhelmingly intense. When I squeeze her breasts, they're soft, squishy, and incredibly tender! While enduring the strain on her shoulders and the sheer weight, she still maintains that sexy firmness—so I keep groping them nonstop! Sora says she hasn't had a boyfriend for a long time, and the reason is simple—she just wants to have sex with all kinds of guys. Yet she insists, "I'm not some slut!" But come on, look at her grinning while giving head—total slut confirmed, lol. She's definitely sucked countless dicks by now. And shoved just as many between those massive tits... While thinking these things, I thoroughly enjoyed Sora's titfuck. She even says, "It's cute how it twitches between my breasts," then starts increasing the pace of her titjob... Ahh, I can't... I'm done... And just like that, I explosively cum. But Sora, you definitely want it inside, right? Then hurry up and get this old man hard again!! ...As I watch her provocative self-titjob, my cock quickly revives! Alright, time to fuck! Sora's breasts are huge, but her pussy is tight as hell. I pound her hard in missionary, and even from behind, her tits swing wildly, visible over her back. I thrust so hard her breasts shake uncontrollably, bringing her to orgasm again and again. Yet Sora, the slutty K-cup girl, isn't satisfied—she begs for more... more! I try grabbing her bouncing tits to stop the motion, but one hand isn't enough to hold them... And so, we keep fucking relentlessly. I managed to hold out despite cumming heavily once, but now a second climax is approaching... In the end, I unleash a massive, pulsating creampie deep inside her, eyes locked on her super-sexy K-cup breasts and Sora's ahegao face. Wow... Koyuen is the best!!
