My girlfriend always insists on using condoms—she's never once let me creampie her. But her big-titted sister used her sexy body to seduce me, whispering, "You can creampie me, it's okay." She was a gyaru type, completely different from any girl I'd dated before. I couldn't resist her advances. Though I love my girlfriend, I became obsessed with this older gyaru's bare pussy. It felt so unbelievably good—I couldn't stop. Before I knew it, my girlfriend caught us. Right in front of her, I pounded her sister bareback and unloaded a massive creampie.
