My girlfriend always insists on using condoms and forbids creampie. But her older sister allows creampie, has big tits, a great figure, and is incredibly attractive. When I visit my girlfriend's home, I get seduced by her sister and secretly enjoy sex behind her back. The older sister smiles sweetly and says, "You can creampie me♪." The thrill of betrayal and the pleasure of creampie I can't normally have draw me in. The excitement of not getting caught by my girlfriend is irresistible. Gradually, I fall deeper into temptation, and in the end, I creampie her sister with a massive load right before my girlfriend's eyes.
