It's a bright sunny day, which is good because it means you can go to the Lido where they have a big waterslide instead of the boring indoor pool. In the kitchen, Father is already eating his toast and marmalade, while Mother's tucking into a bowl of her disgusting looking muesli. You settle for cornflakes and just as you sit down, Janet comes in wearing her swimming costume. She must have grown since last year because it's very tight and it's so stretched over her pussy and you can see the slit. She says something about needing a new one and Mother agrees. Your Father looks up from his paper and you see him shift around in his seat.
Janet grabbed a piece of toast and you both meet Susan at the bus stop. Janet's put a white tennis dress on over her costume and looks really sexy. Susan looked pretty good too in short shorts and a T-shirt. You're wearing shorts and a T-shirt as well and are carrying a backpack with all the kit.
On the bus, you all go down to the back seat and you end up sitting between the two girls, who promptly start talking across you. Apart from the driver, the only other people on the bus are an elderly couple sitting right down the front. Janet keeps wriggling about and you see her put her hand up her skirt. "What's the matter? Got an itch," you ask.
"Do you want some help," Susan says, and you detect a little frisson of something. She doesn't wait for a reply but slips off the seat on her knees in front of Janet. She pushes Janet's knees apart and her short skirt rides up, exposing the problem area. "I can see what the problem is," Susan says with a giggle and she slides a finger through the gusset of Janet's costume and tugs at it. "You need to lift your bottom up," she says.
Janet uses her hands to push herself up and now Susan is able to pull her swimsuit away from her pussy where it's cutting in. "Phew, that's better," Janet says as she lowers herself back down. Susan keeps her hand where it was and you realise that she now has two fingers buried in your kid sister's pussy. Your cock is stuck down the leg of your shorts and, acting on impulse, you catch hold of Susan's spare hand and put it on your thigh.
She giggles and wraps her fingers around your stiff shaft. You look down the bus and wonder what the driver can see in his mirror, but Susan keeps squeezing and pulling your cock while diddling Janet at the same time. Suddenly, she stands up and you see that she has spotted the conductor coming to check tickets.
