An encounter in the night

Kim couldn't sleep and decided to make herself a cup of tea. She quietly got out of bed so as not to wake Roger, and crept toward the stairs. She noticed the light was on in the spare room where she had heard Roger's son earlier. The thought of her earlier curiosity and arousal about the noises coming from that room made her wet. She realised she'd forgotten about Ben being here when she'd got out of bed, otherwise she'd have put her dressing gown on. Instead all she wore were her panties and a flimsy loose fitting night dress that barely covered her ass and hung loosely over her large breasts.

Kim felt slightly exposed, hovering at the top of the stairs, aroused thinking about Ben and what she would have seen if she'd investigated those noises before. She wasn't expecting the door she was staring at to open. Ben stepped out wearing just a pair of boxer shorts. The pair stared at each other uncomfortably for a second. It was Kim that broke the silence, "For god's sake Ben, put some clothes on!"

"I could say the same to you", Ben smirked. Kim blushed at this and tried to pull her night dress down. This only succeeded in increasing the amount of her cleavage on view. She could see him looking, and that made her both uncomfortable and proud that she was worth staring at.

"I am wearing a night dress, not just my underwear. Now please go and put some clothes on", Kim implored Ben before heading downstairs to make herself a cup of tea.

Ben returned to his room, and slid a t-shirt on. He couldn't believe how sexy his step-mom looked in that skimpy night dress. She'd certainly kept in shape, and those breasts were magnificent. They'd looked like they wanted to jump right out of that night dress. Ben wanted another look at them, and he was hungry so he figured he'd get himself something to eat from the kitchen and maybe catch another glimpse of those huge tits.

Downstairs Kim was distracted thinking about Ben's muscular young body, and managed to spill milk all over the floor. She grabbed a cloth and sunk to her knees to mop it up. It was then that Ben walked in. Kim was scrubbing the floor facing toward him. She lifted her head to say something to him, but Ben didn't hear a word of it. As she lifted her head he could see her loose night dress hung low enough that her ripe, full breasts and juicy nipples were completely exposed.

Kim was staring at him with an expectant look on her face, clearly waiting for an answer to a question Ben hadn't heard. Ben couldn't take his eyes off Kim's tits, and it took him a while to realise she wasn't staring expectantly, more in shock. Looking down he realised he had a clearly visible hard-on jutting outwards in his boxers.
