Hearing Lucy's word I said," of course Lucy for you anything".
Lucy said," don't talk nonsense and f*CK me already".
I said," okay".
Then I began to f*CK Lucy while Oreo who was looking at us making love could not suppress her desire so she bent down and stuck her ass and said," Robin play with my pussy".
I saw her Oreo's ass and then decided to use black card skill sensitivity. So I activated it two times sensitivity which made Lucy have her orgasm within the next few seconds Oreo was shaking her ass and she said," F*CK Robin your finger feels so good. Play with it more".
As I fingered Oreo in the next few seconds she also had her orgasm.
After trying my sensitivity skill I go the following result.
First, it doesn't increase my body sensitivity rather it increases the sensitivity of the person with physical contact.
Second, it could be used for torturing and getting information.
