Erika decided to take advantage of something she had but her sister did not; her much larger bust. Pulling back, she grinned up at her servant and slid down the straps of her dress, letting it fall to her waist and expose those lush swells. She cupped the ample mounds, squeezing them together, her nipples stiff little peaks. Pressing in close, she trapped Galen's cock between her tits, massaging the soft swells against his achingly hard shaft. A few inches of his cock was exposed between those tits so that's what she worked on, her lips sealing back around his head and suckling softly, gliding up and down those thick inches.
