Carter Cruise is always over your house using the pool whenever your sister isn't home. She's been her best friend for as long as you can remember. Looking out the window at her tight tan body and wet skin in the hot tub. You start getting hard as she takes the water and starts rubbing her tits as if she knows you're watching. Every time you think you're caught she looks away, that was a close call. Carter comes back inside and asks you if you enjoyed the show. She has more to show you and it is what you have always been waiting for.
