Close up handjob with urethral penetration - part 4

Part 4: When sounding with the glass drinking straw, my mistress is always very careful, as the glass must be well wetted with lubricant. It seems to work best with oil. She makes sure that the rod slides smoothly into my penis. It is also very helpful if the cock is already dripping with excitement. She carefully inserts the tube all the way to the end. The sperm enters the tube very deeply during orgasm and can thus be extracted easily and almost without loss.
