Give you a golden drink

Your sister moans as you continue to lick and suck on her pussy, knowing how to make her feel good. You know your morning ritual well and know what is likely going to come from her. "Time for your drink sis. Make sure not to spill a drop." She says with a giggle. Before she was finished speaking, she pressed you against her pussy even harder and started to piss in your mouth. Her piss was warm and familiar, like all of your family's piss, and you greedily drank it up now. You are often used as a toilet for your family and while when you were younger, you opposed it now you enjoy it a lot and drinking their piss alone can often make you orgasm.

As you drink your sister's piss, you cum again and soaked your fingers and legs, even more, causing your sister the laugh. "God you are such a piss slut. I love how you can cum from drinking piss. It makes you such a good toilet for the family." she said.

As she finished pissing you could hear the sounds of someone walking into your room and could only assume that it was your older sister Katie. When Rebecca was finished pissing she quickly came and started to squirt into your mouth as you lapped her remaining piss and swallowed her juices. She finally let go of your head, and you could finally take your hand out of your pussy, which you did slowly. You sat up and looked at Katie who was still naked, only just waking up.
