I read a story on here a while back, a woman and her boyfriend and her sister and her boyfriend all sharing a beach house. The woman does not like her sister's boyfriend. The woman's boyfriend comes in late from working and is very tired. The woman ended up needing more sunscreen, goes back to beach house and sister's boyfriend follows her, he ends up coming on to her in the kitchen. He eats her out on the counter, they end up breaking a glass, then have sex and he pulls out and makes her swallow his cum. I feel like the title had something to do with emerald, but I can't remember for sure. Anyone know what story I am thinking of?
