Let her ungag herself...

Helen reached up behind her head and unbuckled the gag and sucked of some salive from the ball before she removed it. The ballgag flopped down to her crotch unceremoniously. "Thank you Mr Johnson. I really love your birthday gift." She said and snuggled up more next to me. I kissed her on the cheek and hugged her. "Thank you for submitting to me, I really enjoyed myself."

After that you started making out passionetly. As we keept it up I pushed her down on the sofa and started to finger her pussy. As she starts moan higher and higher I decided to simply clamp my hand down over her mouth. "Now now, don´t wanna wake the neighbours?"

Helen came soon after I started rubbing her G-spot. That´s also when I heard a car coming up the driveway. Both me and Helen froze, terrified!
