Hand fired from behind! (2)

It was sudden! The hot and soft two bulbs that I feel on my back, the hot breath that blows gently to my ear, and the girl who spans me behind her hold me tight. I couldn't move for a moment. But only the Po Po reacts. She is glad to have a sock and a swell. I can't put up with her hand feeling as she feels her warmth in the whole body. It is packed in all seven corners.
