She is a high-class young lady with an elegant and intelligent aura who attends a famous private university. However, after tasting my big cock with her freshly awakened adolescent pussy, she became a convenient onahole woman who offers her pussy whenever I call her because I want to cum, despite her pure and cute appearance. Her personality and looks are great, and she's a convenient woman to use as an onahole, so I have no complaints. But after fucking the same pussy many times, I naturally started to get bored, so this time, I decided to suggest losing her anal virginity. Being naturally refined, she seemed unable to comprehend the idea of having a penis inserted into her anus and reacted with rejection, wearing an anxious expression. But since she's a slut who drowns in sex for the sake of a huge cock, when I tempted her by saying, "Everyone says it feels better than a pussy," she began to pant heavily, unable to hide that she was getting horny from the fantasy that her own asshole would bring more pleasure than her pussy. "Did you get horny just from imagining it? Then your asshole is confirmed," I said, and decided to give my huge cock to her anal. When I made her crawl on the floor on all fours with her private parts fully exposed, she was terrified, saying, "It's my first time, so please be gentle..." However, her horny pussy was overflowing with juices in anticipation of being penetrated in the ass. Using that pussy juice as lotion, I thrust my finger up to the first joint into her asshole, and she immediately climaxed with a super lewd reaction, screaming, "Ah, no... I'm cumming from my ass, not my pussy!" I was amazed by her slutty behavior, which lacked any dignity of a high-class lady. I stuffed a massive cock that could dislocate her jaw into her mouth, and while making her stroke it with her throat, I pressed her, "Where do you want this big cock to go?" She gagged with tears in her eyes and miserably begged for anal fucking herself, "Please put it in my ass...!" Although she pretends to be refined, she revealed her true nature as a total pervert who climaxes through her asshole. As the abnormally large cock was tightly buried into her anal, she initially wore a pained expression, but when I thrust it in all the way to the base without hesitation, she cried out in admiration at losing her anal virginity, "Ah, my stomach is full of big cock, amazing... amazing!" When I pistoned her just like I would her pussy, she writhed so intensely that her pupils dilated wide open and she almost lost consciousness from the sheer pleasure. With both her pussy and anal drenched and soiled with cum, the aura of the refined high-class lady completely vanished, and she fell into being a semen-toilet woman.
