Even if you have a girlfriend you love, you're still a man, so you can't help but have a thing for big breasts.
Your eyes are instinctively drawn to big breasts.
But my girlfriend is quick to notice this.
And then my girlfriend gets angry.
But she doesn't just get angry.

Jealousy is the aphrodisiac fuel that makes her incredibly passionate and erotic.

She sucks out all my sperm until I'm completely satisfied, then teases my nipples with an angry look on her face.

My weak-willed dick is always overwhelmed by her jealousy.
