Obviously the real pleasure is in the young but 姣, 這些不是沒有可能性, 但需要MM本人愛好色情。She needs to like it enough to persue the feel and have a boyfriend who can teach her or patient enough to match her enthusiasm. Young boys are often to quick to spill their juice to make it last so the girls just know ti lie there and do nothing because it would be over in 30 seconds. It therefore, take a few years in the business for them to discover the pleasure. By that time, they are too old to be picked.
I agree with 7Siu, alternate thethe choices. play but know the limitations of each. Just like picking for looks or boobs. that, I know 7Siu's preference. Haha
