Mike took three dildo's. First one was dark blue one, a very long slender and smooth rubber dildo. But it was solid like a club. it was no thicker than thumb at the tip but it rapidly widened to thick as adult man's wrist. Mike said; "Well, try this one. It widens after the tip and you can train stretching by pressing more of it into your ass. Just keep a constant motion, going back and forth while stretching." Mike took a lube and poured some clear substance on the dildo, he spreads it with his hand, making the whole dildo glisten expect small area at the base. Free from oil so Anna can get a solid grip on it. Mike then says; "Also you need find comfortable position as possible when you stretch. Comfortable at least you do not anyway pressure your stomach nor ass with muscle activity." Mike then is giving the dildo towards Anna, up to her now experiment with it.
