Endless Pleasure Training with My Gloomy, Well-Endowed Ex

It's been 2 weeks since I broke up with my boyfriend. "A guy who tracks your location with GPS is no good" (according to a friend)—that's the truth. The heroine is calling every day, hasn't blocked him on social media, and her words don't match her actions—are they really broken up? You know, those kinds of women. "I don't mind being a sex friend, I just want to be by your side." A guy who says that is no good, but she's no better, saying things like, "If we're both just looking for sex, it's better to be with someone I know well." Even though I know it's abnormal, she's been bathed in his obsessive love and is in a state of dependency. The two reunite, but 憲一郎くん's behavior is like that of an abusive boyfriend. Scary. When the heroine kisses him, he completely changes. The look in 憲一郎くん's eyes when he changes is so intense it's terrifying, and the forced kiss while holding her neck is also way too scary. "I can't wait for a shower because I'm just here for sex"—what kind of reason is that? lol I had to laugh. The heroine is exhausted just from the foreplay. 憲一郎くん teasing her is mean and amazing, and the scene where she begs for penetration was super erotic and great. The heroine is about to climax right after penetration, but he calls sex a collaborative effort to feel good together and keeps pushing her until she's completely confused. 憲一郎くん's technique is incredible... By the way, what does "syncing our breathing" even mean?! lol Even if they fight or have issues, in the end, her thoughts are completely destroyed by 憲一郎くん's huge cock and she goes back to him. You can't beat a huge cock. Everything is forgiven. It was 憲一郎くん's turn the whole time, but then it became the heroine's turn once. He said he'd stop all the crazy things he's been doing just to be with her, followed by intense sex, so I thought, "Oh, so this is a happy(?) ending." But then 憲一郎くん calmly asked, "What's your answer?" That was scary lol. The way he kept pushing her, saying it wouldn't end until they got back together, was very erotic but genuinely terrifying. After reading the ending, I felt relieved that he was just a normal guy who loved the heroine too much, someone who could return to the side of normal people(?). Thank you for this wonderful work.
