After a weekend of hunting for male barbie dolls that bend at the knee (with no luck) I have managed to come up with another position that Ken and Kenneth are quite capable of doing. However, by next Wednesday, hopefully they will be further evolved and be able to fuck in a world of new ways!
This position is rather simple but the key is eye contact. Straddle your man and let him bounce you up and down. Then the rest is up to you, get verbal, move your arms, switch it up, and repeat!
