This is a small story about a straight couple in which both partners are open to share and try fantasies.
The man's name is Nick. He's an average body guy, with short brown hair and brown eyes and an attractive 20cm cock when hard.
The woman's name is Helen. She is short, with long blonde hair and has a beautiful pair of big breasts and a nice fit ass.
It's 11 pm, the time Nick and Helen usually go to bed. Nick approaches the bathroom sink to brush his teeth. However, he finds that his toothbrush is missing. Soon, his partner, Helen, appears at the bathroom's door.
"Looking for something honey?" says Helen.
"I am looking for my toothbrush, did you throw it away?"
Helen smiles and says "Not exactly, I just had to use it for a while."
She slightly raises the night dress she's wearing. Nick notices something sticking out from under her dress. Some blood starts rushing into his cock as he realizes where his toothbrush has been.
"Go ahead, you can brush your teeth now, I don't need it anymore."
Nick approaches Helen and kneels down in front of her legs. He reaches for the toothbrush and slowly pulls it out of her butthole. Helen moans a little in an attempt to arouse Nick even more.
"You know... I like when you do things like this." says Nick.
"I know" she says as she looks at the hard cock in his pants.
Nick starts brushing his teeth while Helen stays there and observes.
"I had an idea we could try. You've always talked about how you find me hot while I am sleeping. So here is the idea: Each night one of us uses the other during their sleep, in turns. You don't reveal anything in the morning. Just be careful not to wake me up. You can be the first one tonight".
Nick's cock starts getting harder as he hears the idea, thinking of the possible ways he could exploit his partner.
