Nothing personal.

Oz held her in that position and he grabbed hold of her leg which wanted to go down, so she was now slightly made to spread her legs as if she were a dog taking a piss. She felt very embarrassed and couldn’t say anything. The act of balancing herself on one foot was taking enough of her attention. Meanwhile Oz caressed the insides of her thighs and rubbed around her buttocks with his free hand. Maria seemed ticklish upon doing so, so he kept doing it until he saw that her panties were getting slightly damp again. It was at this point he realised that she was probably beginning to enjoy his caressing.

His free hand went towards her large buttock again, he pressed his finger into her panties right where her butthole was and began to prod against it in a rhythmical motion. Her butt squeezed gently on his finger and he felt a twitching beneath the fabric. Maria gave out a little shriek, but was barely able to do anything against it while keeping her position. Once Oz loosened his finger on her butt, he moved his hands towards her crotch. When Maria felt the finger approach her vulva and imagined the touch of his strong finger on her sensitive skin, she shook violently and lost her footing.

Oz noticed that she began to fall down, together with a few packs of canned tuna, so he quickly extended his other hand too. In this way: in one arm he was holding on to her by her shoulder and back area, while with the other he kept a firm grasp on her buttocks.
