Head for home first

As John got home, his gorgeous mother greeted him, she'd always been called a MILF by all of his mates; she had divorced his dad 4 years ago, and hadnt met anyone since- he didnt know how- with blonde hair with large D cup breasts, and she was in such good shape for a 42 year old, her ass was renound across the village, it was an older womans ass, but was still amazing.
"hey John, you've been a while! Anyway your sisters are still out and im going upstairs for a bit."
His sisters were Daisy his bubbly younger sister, she was cute with brown hair and a pretty face. She used to be insecure as she was quite chubby but she's lost all the weight and now is just left with the tits! They are DD cup and she only just learnt what they can do to men, so wears alot of low cut tops.
His older sister Fiona was 23 and completely different; she was very strict and domineering. She also had brown hair but had a more athletic figure, not that she showed it off too much- with her new job she practically lived in her business suits, attempting to be conservative, it was still quite sexy.
To his surprise she took absolutely no notice to the pretty blonde in fancy dress standing next to him.
" I'm invisible to everyone else, unless you state otherwise"
"oh right, cool, i guess, What do you wanna do then Gina?"
She laughed cutely "i think thats my question, its all up to you"
