Perhaps sensing your change, Faye calms down, and says: "That's it, just let it all come out!"
You pump into her faster and faster, passing the point of no return.
Then just as you start cumming, Faye says "Now!". Then Sydney grabs you by the shoulder and pulls, while Faye pushes you off of her! Together they both ruin your orgasm!
Your ejaculate drips helplessly into the condom as you scream, begging them to let your cock back into Faye's pussy. Sydney holds your arms behind your back so you can't stroke yourself... You feel incredibly frustrated and controlled!
