This story contains some pretty extreme enhancement of genitals. Please skip the story if that is not your cup of tea.
Nikki walked towards the 2 women and kissed the taller one on the lips. Then she bent down and kissed her new wife for quite a while, also on the lips. Then Nikki showed them both to Leah.
'Guy's I want you to meet my daughter Leah. Leah this is your new grand mother, Sherry.' Nikki pointed towards the red head woman.
'And this is your new mum Sasha,' Nikki pointed towards the girl.
Sherry gasped. 'Oh my God, you are absolutely beautiful, Leah. I never expected to become a grandmother at the age of 23 let alone be the grandmother of a super hot busty girl like you. My God those boobs are huge, can you even touch your own nipples?' Sherry said softly giving a squeeze to Leah's nipples.
Leah giggled. 'I can barely touch my nipples grandma, they feel like they grow every day. I hope you like them.' Leah said cheerfully hugging her new grandma.
'I definitely like them honey,' Sasha finally spoke. She sounded so much older than her age, and much more mature. 'No daughter of mine is going to fall behind on the genitals department.' Sasha said with a wink.
Leah hugged her new mother. 'Mum your penis, its just amazing,' Leah said softly touching the limp vascular shaft.
'I don't know where she gets it from, definitely not from me.' Sherry commented.
'I just said the same thing to Leah about her tits,' Nikki said laughing.
'Like mother like daughter,' Leah said giggling as she stood beside her new 10 year old mum.
'But one problem, it's going to get confusing calling you both mum,' Leah looked at Nikki and Sasha.
All 4 women fell deep in thought.
'Hmm, I know. How about you call me penis mum and you call Nikki pussy mum?' Sasha came up with a solution.
'That sounds great and so erotic penis mum,' Leah jumped up with joy.
'I wish I had a bigger mouth penis mum so I can give you a blow job as a thank you. But your penis is so big.'
'Yeah sorry baby. It's about 6 inches in diameter when I'm limp, but gets bigger when I get hard.' Sasha winked.
'Oh my God, really? But it's already like a 3rd leg for you and that's when its limp? I have the best penis mum ever!' Leah yelped in excitement.
'Well you wouldn't want anything less for a girl with such huge tits now will you? So how about you get on that sun bed and give your penis mum a nice boob job?' Sasha asked.
'Oh my God, that sounds great penis mum.' Leah instantly got up on the sun bed and lay down obediently. Her giant tits pointing straight up at the clear sky.
'Hold on Leah honey, let me lube you.' Sherry got out a bottle of lube and squirted the entire bottle all over Leah's monster breasts. Leah's breasts looked amazing with so much lube on them.
Sasha got up on the sun bed, put both her legs on the bed beside Leah's stomach then she softly rested her penis against Leah's breasts. Sasha was already semi hard.
'Grandma do you think you can finger my pussy? I don't think I can take on my 10 year old mother with such a monster cock without some pussy action.'
'Sure baby.' Sherry pulled aside Leah's tear drop crotch of her g-string and began to finger fuck her pussy like an expert.
Leah bit her lower lips and squeezed her tits together and looked up at her penis mum.
'I am ready for you penis mum.' Leah said.
'Alright baby, show mummy how much you love her.' Sasha whispered then she slowly pushed her penis in between Leah's tits and then started to thrust.
Leah felt like she was ready to die, being fingered and watching the humongous circumcised mushroom head of her mothers cock coming and going away from her face with each thrust. Sasha had to hold on to Nikki for support, her penis was now fully hard and it was becoming difficult for her body to thrust that giant thing. Nikki had one hand at the back of Sasha's waist helping her thrust.
'FUCKKK OH MY GOD, GRANDMA YOU ARE SO FUCKING GOOD AT FINGERING.' Leah screamed.
'Squeeze your tits tighter Leah baby. Squeeze your tits tighter for your 10 year old penis mum.' Sasha moaned as she carried on thrusting with enormous will power.
Leah had her eyes closed the whole time due to the pleasure shooting through her body. But she opened her eyes a little and almost fainted from what she saw. Sasha's penis was now fully hard and it was just heavenly to look at. It must have been well over 35 inch long by now. It was still 6 inches in diameter at the base, but it got thicker as you got further away from the base and closer to the tip. The tip must have been over 15 inches in diameter. Her 10 year old mums cock was literally like a tree trunk. Sasha's penis was nearly as big as her own body if not bigger. Then Leah saw the smooth mushroom tip coming and going through the gap between her tits and she saw the monster piss hole that a 15 inch wide dick head would have. The tip of her 10 year old mum's dick had a piss slit nearly as big as the width of a coke can and it was opening up even further every time Sasha thrust and the dick came close to Leah's face.
'Oh Fuck that elephant cock.' Was all Leah could muster before she came, pissed and shat herself all in one go and then fell unconscious.
