"Okay, sister dear. Your son was generous enough to give me a fresh cream pie so get naked and dive in. It's been a long time since you've eaten me out! And you are such a good pussy licker!"
"It's been just a month, for God's sake!"
"But, this time it's covered with your son's slimy semen... Oh, easy... I've just come a jillion times on that big cock... and his tongue! You should know that I've been giving him lessons just so he can please you... Here I go again. Damn, you're good! You made me see flashes of light!"
"I think that was Bobby taking our picture. Hey, Son. Is that photo for the Internet or some kind of blackmail?"
"Both," I said. "It's just to make sure that Dad doesn't learn about the three of us from Aunty Helen."
Mom and her twin got out of bed and walked into the bathroom. Mom called out, "You'd better get in here quick and DO NOT bring the camera or I'll piss on IT!"
When I entered the bathroom, mother was squatting over her sister who was lying in the bottom of the bath tub. My Aunt was holding her own labia open so when Mom let loose with her pee, it splashed Helen's clit and all over her pussy.
"Oh, that feels good! Let me do you now..." and they changed positions.
"Let her flow!" said Mom. Mom rapidly rubbed the urine into her pubic hair trying to masturbate before Helen emptied her bladder completely. "Save some for my face... Come up here... Aim for my mouth... Aarrgh."
"Sorry, sis'" Helen panted. "I forgot you liked the taste of my pee. Bobby get over here. Give your mother what she needs... That's it. Put your feet between her legs and point your cock at her pussy. Now start peeing. Good. Hazel! Hold your pussy open wide! Tilt that pelvis up so he can pee right up your hole! Hot damn! Now, Bobby, aim for her nipples... Uh huh! And give it all the rest in that little mouth of hers. Hazel, don't swallow! Just let your son's piss fill it up! Just fan-fucking-tastic! Now, close your mouth. Don't swallow. Stand up. Bobby help her. Hold onto her. Now, kiss her and taste your own piss! I now pronounce you soul mates!"
"Someone turn on the shower. We've made a real mess in here..."

"Bobby wants to see us sixty-nine."
"And what's your son going to be doing? Taking our picture again?"
"I suppose so but if you let me be on the bottom and point your sweet ass toward the bottom of the bed, I'll ask him to fuck you again -- just to make sure that you're pregnant... And I'll make sure that he goes in the right hole this time! That was a joke..."
"An offer I can't refuse. Okay, Bobby, watch this."
