Mark didn’t really know what to think of the sisters now, but it was clear to him they both liked him.
When Mark entered the hallway, Zoe came out of her room, her soft 3 inches cock dangling in front of her pussy.
ZOE – You taking a shower too? Wash my back?
MARK – Sure, why not.
ZOE -Wow, why are you covered in cum? It must be nice being able to ejaculate like that, we stroke it, but we only ever get frustrated.
MARK – It sure is great, but at least you have a pussy. Now come on, before someone else wakes up.
Both of them got under the shower and started washing each other.
ZOE – We have to back to school tomorrow...I like school, but I’m so tired already.
MARK – I know Z, me too, but look at the bright side, we can go see our friends.
ZOE – What friends?
MARK – Come on, look at these!
Mark reached around her to grab at her boobs, making Zoe moan.
MARK – With these, you can make as many friends as you want.
As Mark squeezed her tits his erection built between her legs, as did hers. He then let one of his hands go down to meet her cock.
MARK – Some people might be intimidated by this, but you don’t need to befriend those people. And remember, I’m always here.
As Mark jerked Zoe’s sick with his dick rubbing her pussy, small orbs began to form and rapidly grow, soon they were at the right size for Zoe to cum from her penis for the first time. The orgasm was so potent she fell to her knees.
ZOE - ***Pant***I love you brother ***pant ***
MARK – I love you too sis, now let’s finish this before we use all the hot water.
