Here is another useful tip:
Targeted Audience - married couples, about-to-divorce couples, not-creative couples, one-night-stand people, etc.
1) When banging in and out, try not to rush like a bull....
2) Begin with half-depth insertion
3) Follow by full-depth insertion
4) Retrieve your weapon and stay in the air for a while...then push violently inside...and very quickly, pull it out again and wait outside again....
5) Repeat step (4) for 5-10 min...
6) Pump gently for 10-15min until the 'engine' is warm...
7) Apply the 3-shallow, 1-deep penetration theory....

Then free style leow......
