She claims the magic wand isnt powerful enough to do anything for her, but you insist she proceed for 2-minutes, and after a few seconds, Beth admits that it feels pretty good. She begins to squirm and actually looks like shes enjoying it. After a minute or so, Beth confesses that it feels very good and she starts begging you to let her stop. But youre in charge and make her keep going much, much longer than the 2-minutes you said several minutes ago. It all proves too much for her after 10-minutes. After she cums, she tells you, You win!
