Every woman should master the art = and it is an art = of using her pussy lips to massage a cock like that. It takes self discipline from both the man and woman but it is worth it to the man. Plus, I guarantee that who receives that as foreplay will get (or stay) hard again and make it worth her while.
How he stayed limp when she initially put thee lube oil on his cock is beyond my comprehension. When a babe like her talks like that and touches me, I immediately get hard as steel.
