[Full stroke with both hands very tight to M=50 to the edge]
Now the girls join the energy and begin to stroke together with two hands one for the shaft and the other for the head, stimulating all the cock simultaneously. The feeling is amazing, even if the rate is very slow the edge gets close relentlessly.
GIRLS: Do you like the double special attack? The slow rate permits to feel every step that your cock makes to the edge.
KELLY: Wow, very nice technique! I admit that you are ready to become expert.
