My twin step-sister is such a slut you know. So we still share a bedroom (which is annoying) and I swear every night before we go to bed (after we say goodnight to step-daddy), she starts making funny noises below me in our bunk bed. She starts breathing heavily, then she starts moaning like she's hurting herself. I'm always too scared to look and see what she's doing... Then I start hearing these wet noises, like a sploshing sound. Like the sound your hands make when your washing with soap you know? It sounds gross. I can't every imagine what she's doing. It last's about 10 minutes with her moaning and this wet sound getting louder and louder and faster and faster. I'm sure she thinks I'm asleep. Then the bed starts shacking and she lets out this little scream and then I usually see this watery stuff spray across the room. It startles me. I think whether she has a squirting water toy or something that she plays with but it sounds so silly. The last few nights I've started touching myself while she makes these sounds. I feel really naughty doing it but I have this urge to touch and rub my fanny. Last night my fanny got so wet and it was like I was weeing. I was so embarrassed but it felt amazing. If she knew what I was doing she would think I'm so dirty, I'm her twin step-sister!! But tonight I think I'm going to pluck up the courage and look over the bed to see what she's doing, I need to know why she makes those funny sounds....
