Masturbating in my girlfriend's underwear

I love nothing more than getting up early and sneaking into my girlfriend's room to play with her panties. It's a guilty pleasure, but one that I can't resist. The soft fabric against my skin, the delicate lace at the edge, it all sends shivers down my spine. I can't help but imagine what she would taste like, her sweet scent lingering on the fabric. I've been doing this for years, and I don't plan on stopping anytime soon. It's a secret I keep to myself, a little act of rebellion against the mundanity of our daily lives. It's a way to keep her close, even when she's not around. I hope she never finds out, but a part of me hopes she does. Maybe then, we could explore this side of our relationship together. For now, though, I'll continue to steal her panties and pleasure myself in the morning light, lost in my own world of lust and desire.
