You Are Not Sure.

You stand there as Gwen continues to fuck your thighs. You reach down and start to play with the head of her cock as it pokes out from between your thighs. You then push it up against you clit harder. Her head was now on your shoulder as she continued to give off deep grunts. She was lost in heaven as you were getting closer to the edge with her movements. However like before you didn't seem to get there.

'Fuck' you cursed to yourself as you pussy continued to leak down your thighs. Gwen's cock was mere millimeters from giving you the pleasure you need but that tiny voice inside your head was still screaming to stop. Gwen started to speak.

"Sara I need to get off but I can't quite get there. Maybe we could try something different." Gwen says as you feel her start to shift. Her cock was still thrusting but moving the angle.
