and hes is pushing his pelvic area forward and rolling his hips
and shes bumping her butt on him

i was bubbling with this guy and he pulled me so tight to him, i could barely grind
i love bubbling its like GRINDING but better she usually goes full out- head down ass up
Very new drug craze mostly contained to the east coast of the united states.
