Titfuck

"First of all..." You say, sitting on the bed. "I think **** needs to earn my cock."
Sue whines pitifully, making you even harder than you were before. You beckon her closer with a finger, and she scurries to her knees in front of you, eyes welling up with tears.
"Please master...just fuck me..."
"Not yet." You say absent-mindedly. "...take your top off."
Sue sighs and unzipps her suit, pulling it down to her waist and letting her glorious breasts bounce free. Smiling, you tweak a nipple, making her breath catch in her throat again. "I know what you can do with these."
You pull your trousers down, and Sue's eyes widen with lust. "Wrap your tits around them, and maybe I'll let you feel master's cock inside you."
Sue obeys instantly, kneeling forward and wrapping your cock with her breasts. Spitting down to lubricate them, she immediately starts bouncing up and down, staring up at you with desire and hope as she did so.
"Am I doing well, master?"
You gasp from the feeling and grin. "Yes, ****...carry on..."
After a few moments, you feel yourself rapidly approaching orgasm.
