I'm eighteen and live with my mother and older sister. My old man took off ten years ago and the only time we hear from him is when his lawyer gives Mom her alimony check. I had always planned to move out and get my own place as soon as I turned eighteen but now I think I'll stay.
Day before yesterday, Saturday, Mom and Sarah went shopping and I cleaned up the yard after Friday's storm. I was still at it when they came home, yacking away a mile a minute like they always do.
It was a nice warm spring say and I saw Mom opening up the windows. When I went past her bedroom window I stopped short, the window was open, the blind was up and Mom and Sarah were trying on the clothes they bought. We were a fairly easygoing family but this was the first time I ever saw either one of them in their underwear. Sarah saw me watching and said something to Mom, Mom said something to her and they both laughed. But they didn't pull the blind down. So I took that as an invitation to get a closer look.
I leaned on the window sill and grinned, "You're lucky it's only me out here, what if I'd been some pervert and saw you half naked?"
"I'd say there's already a pervert watching us, wouldn't you, Mother?"
"Oh, I don't know, I guess it's normal for a boy to want to see women change clothes."
"Don't let me stop you. Like you say, it's normal for a man to watch women changing clothes," then I got brave, "You didn't happen to buy any new undies, did you?"
"Jesus, Mother, I think he wants us to strip for him."
"It does sound that way, doesn't it?"
Sarah came closer to the window and reached for the blind, "If you want to see any more you're going to have to come inside. We're not entertaining the whole neighborhood."
She pulled the shade and I ran to Mom's room.
Sarah still had her panties and bra on, Mom had removed her bra and had her back to me, taking off her panties. I stopped at the door and gawked.
"Your horny son's here, Mother."
Mom looked over her shoulder, "You're not coming in here like that. Leave your clothes in your room."
I flew across the hall, stripped and hurried back.
"Whoa, would you look at the love muscle on the kid!"
"You wrap your twat around this love muscle and you won't call me kid anymore."
"Is that an invitation or a challenge?"
