You and Sophia time your thrusts into Emma

Without exchanging words - just looking at each others eyes you and Sophia connect in your current endeavors - you want to give Sophia the best, most glorious, over the top fuck of her life.

You time your thrusts to match so that while Sophia's big cock sends a shock wave of pleasure through Emma's body your cock, filling her mouth disorients her from making sense of the moment. She cannot think about how her best friend is fucking her - she cannot think about anything - she is simply consumed by sex.

You and Sophia continue to treat your girlfriend like the sex object she is. Sophia doesn't even know that Emma is actually your sex **** - but that hasn't prevented her from using her best friend as a fuck hole.

You lock eyes with Sophia and she gives you a smile, a sexy smile that you've never seen from her - she's always been too reserved. She's so sexy when she's in her element. You've always imagined what she looked like when she was having sex - or specifically what it would look like if you were fucking her - but this, you imagine, watching her fuck someone else (your girlfriend and her best friend nevertheless) was beyond your wildest fantasies. Sophia is just pure sexiness.
