Yin Lu and I can be regarded as an old couple. In the count of the confrontation on the bed, we have already had a full and detailed understanding of each other's bodies. Just as I know almost all the sensitive belts on her body, she is also familiar with how to arouse my impulse. This familiarity has made us feel a little more tacit understanding, but it must have been less passionate. Just like a middle-aged couple, close their eyes and complete a piston movement like holding their left and right hands in a very familiar way. Yin Lu and I are also experiencing the crisis after the passion fades away recently. I often look at Yin Lu's beautiful face and are very excited, but when I get on the bed, I don't feel very good.
