Her finger slipped inside the knicker elastic round my legs. I looked up to see her smiling at me. “That’s fine isn’t it?” she said “so come a little closer, young man”.

I moved forward and felt her right hand slide inside the knickers and rub against my member; I could feel it start to grow under her caress, but she didn’t stop just smiled again and gripped me tighter.

“Mmm,” she whispered, “you are growing up aren’t you Alex”. Her other hand started to pull my blue school knickers aside as she said, “We don’t want you spoiling another pair of panties now do we?”

I could feel my member start to peep out of the knicker leg as she bent over me. I closed my eyes and then I felt something warm, soft and wet move over my rigid member. I felt a hand hold my testicles, and just before I erupted into her mouth, she pulled away, tucking me back into the knickers.

She gave me a hug and said,” hurry now, Alex,” as her hand went round and felt my bum, “Pull up you trousers”.  But it was to late, I was now very wet and sticky.

She winked at me and said, ”I will be checking you put on clean panties when we get back”.

I hastily pulled up my trousers and set off behind her down the hill after the others.
