Sexy Fun Times/Sleep/Mom

"Anyone home?"

You are standing in the shower with your cock in your hand, thinking about Katie's cute ass when you hear your Mom. She has her own key, so by the time you grab your robe, she is already in the sitting room. "Hi, Mom... Coffee?" you say and head for the kitchen.

"Where's Katie, she asks and you realise that your ten-year-old sister is probably still sprawled out on your bed as naked as the day she was born.

"Did you enjoy your date," you ask, hoping to distract her, but too late. She goes straight into your bedroom you hear voices through the closed door. There's not much you can do now, but finish making the coffee and you're sitting on the couch, halfway through yours, when Mom comes out leading your naked sister by the hand.

"It looks as if you enjoyed your date," Mom says and turns to Katie. "I think you'd better go get a shower don't you young lady." Katie giggles and runs off to the bathroom. Mom pics up her mug and sits down in the armchair opposite you. It's only now that you realise that she still dressed for a night out. A low-cut top that, combined with a push-up bra, reveals a great deal of cleavage, fishnet stockings (she kicked her shoes off as soon as she came in the door), and a short skirt that barely reaches the top of her stockings, showing that she is using an old-fashioned suspender belt to hold them up.

She sipped her coffee and looks at you across the top of the mug. "So?" She says.

In spite of yourself, you can't help blushing. You shrug. "We were just messing around last night and she fell asleep in my bed," you say.

Mum's eyebrows go up. "You think I don't know you fucked her," she says.

You gulp, but then it dawns on you that she doesn't actually seem to be mad at you. "I, I couldn't help myself," you say, turning on the smile that, ever since you were a small boy, always got around her.

She stands up and your cock twitches as you get a glimpse of her red panties under her short skirt. "I'd better go and check on her. She said she was okay, but…" She goes into the bathroom and closes the door behind her leaving you sitting on the couch wondering what the hell is going to happen now.
