Sonic screw-driver

As the Doctor slide in and out of Rose's tight ass, he got his sonic screwdriver out of his pocket. He set it to a very special setting and slipped it into Rose's wet pussy.

"Oh my God," gasped Rose as the sonic screwdriver started giving her a very sonic screw. The sound waves made her pussy vibrate in ways she had never dreamt of. In a matter of moments she was gushing after her first of many orgasms.

The Doctor meanwhile was pounding her ass with all his might, his Time Lord cock able to undergo multiple orgasms whilst remaining rock hard. His first took Rose by surprise as her ass was filled with his cum, but the second and third just added to the intense pleasure she was having.
