Seducing My Sister/First BJ/The Doctor/Swimming
Ever since I was little, Mum's been taking us swimming on Saturday mornings. She works weekday mornings in a shop that sells ladies underwear and they asked her to swap and do Saturdays and take Monday and Tuesday off instead. This means that Dad has to take us.
Usually, Suki gets changed in the ladies with Mum, but Dad can't go in there so she has to come in the gents with us. It isn't a problem since we all have our costumes on under our street clothes, although I did notice Suki staring at a naked boy in the shower. We all had a good time splashing around and Suki went down the big chute for the first time. Mum wouldn't let her before.
After, we all go to get changed and this means that Suki has to get out of her wet bathing costume. It's a one-piece, and pretty tight so she can't manage by herself. She pulls it down to her waist and Dad tells you to help her. You lift her up onto the bench and tug it down over her bum. This means that you get very close to her pussy and you can't help looking. "Girls are so neat down there," you think.
"What are you waiting for," Suki says, giving you a shove. Guiltily, you tug it right down and she puts a hand on your head to keep her balance. You are in a family cubicle, but Dad went for a shower and didn't shut the door. When you look up, there's a boy standing there watching. He's about the same age as you and his dick is sticking straight out in front of him. When he realises that you saw him, he blushes bright red and runs off.
When Dad gets back, with a towel round his waist, you and Suki are dressed. He tries to be discrete, but we both get a good look at his cock as he dries himself off. It's quite shrunk and hanging down at first, but when he notices you both looking, he quickly turns his back.
"Isn't it a bit weird, having all that stuff hanging down between your legs," Suki asks. She's wearing a nightie this evening and you are in shorts, so as you squash up next to her to look at the book, your bare legs are pressed together.
"I dunno, I never thought about it," you say. Thinking about the close-up look you had at her pussy. "Girls are pretty neat though."
"Did you see Dad's willy? It's really big isn't it," she says with an embarrassed giggle. You can't help giggling with her. "Did you notice," she asks.
"What?"
"How it started getting even bigger before he turned round."
"No."
"Well. it did. Why did it do that?"
"It's complicated."
"Why are you going red?" she jabs you with her elbow.
Mum comes up and saves you from further embarrassment. Later on, when she's tucked Suki in and we are downstairs, she says: "We really do appreciate how you get on together. You will let me know if she gets too clingy won't you."
"Is Dad taking us swimming every Saturday now," you ask.
"Probably. It pays more and we are saving up for a special holiday this summer," she says.
