AQUBE-052 - Content depicting the experience of a first girlfriend being sexually assaulted in front of the user, resulting in an erection, and expressing self-loathing. Aimy Mizuki.

I got my first girlfriend. Today is a date at my place! "I've never been to your room before" she says, immediately taking my hand. Could it be she wants to get intimate with me?! But I'm still a virgin. I didn't know what to do after that... "You can be a little more manly and have some courage," my girlfriend said, and I was about to pin her down and lose my virginity today! Just as I was about to kiss her... oh? I got a message from a senior. "You're at home, right? I heard you got a girlfriend? Let me see her for a bit." This senior is scary... if I refuse, it'll be a hassle later, so I guess I have no choice. I'll have to call him... The senior, when he came, praised my girlfriend, saying "She's so cute!" and asked, "Mizuki, can I borrow her for a day?" ...Senior?! Aren't you getting a little too close to my girlfriend? Huh? Are you going to kiss her? Huh, are you going to touch her breasts? Are you going to go to bed?! Watching that, I can no longer stop my excitement!! Yes, I am the pathetic man who gets an erection while watching his girlfriend being sexually assaulted in front of him.
