Keep on exploring

Surprised by the girl's reaction, but sure not one to complain about it, I continued my slow exploration of her sweet little butt.

Within a couple of moments I had worked my way down the back of her panties and in between her slender legs, to where I could feel a spot of wetness forming right at the opening of her delicate pussy.

A soft moan escaped her as I kept investigating, tracing her outer lips with my finger through the silky material of her underwear, while she hesitated and then spread herself wider for me to reach.

Barely believing my luck I delved even further, nudging gently at her clit before going back to tease her by caressing her inner thighs and the outer edges of her mound. The spot in her panties was definitively growing bigger by now, making my fingers all sticky while she started humping herself back into my hand.

If we went on like this then someone would surely notice us, especially if she'd keep on moaning any louder...
