” Mary-Kate said quietly with tears in her eyes.I grinned wickedly as I looked at her. She was a picture on innocence as she stood there in her scho...l uniform. The contrast between her and the lewd scene behind her was really getting me hard. It was time! Time for Mary-Kate to make that irreversible journey from girl to woman.“Come here and sit on my lap Mary-Kate and we can watch and see who cums first. I think Ashley is winning at the moment,” I told Mary-Kate.Mary-Kate gingerly sat down on. Enjoying the naughtiness of masturbating in the car, she slides forward in the seat and her skirt rides up to reveal her smooth fanny. Smiling and again and deciding to leave it until later, she opens the door and swings one leg out.Forgetting that her skirt has ridden right up, she is shocked to see a man standing in the trees, looking in her direction. Still hot from fingering herself and realising that he must have seen her pussy as she swung her leg out, she wonders if it would be possible.

They're getting quite big now, and though I think they looknicer for it, that they better suit his new proportions, he's stillgetting used to the weight and how they force him to walk, etc. Nothing abig girl his age would have too much trouble with, I don't think.

They were both in bathrobes, but as soon as the door was closed behind them they took their robes off. Underneath they were just in bras and panties, Ann in white and Becky in pastel blue. In spite of our previous bravado we boys just sat there staring incredulously at them.Ann picked up a porn magazine, leafed through it and held it open at a centrefold of a girl not much older than herself sprawled nude on a bed.“If you want to see us like this, let’s see some cock first” she said. Ann saying.
