Twisted Desire

We were both hot and went totally with the passion (or maybe it was just lust) we were feeling.  But as my lips slurped up and down Donald's rigid pole, I heard something.  Without stopping, I glanced up at the doorway and saw Jason standing back in the shadows, watching his mother give a blow-job to her date! I couldn't believe my horrendous luck!  The first time I ever did anything like that in the house since my divorce, and I was caught!  But at the same time, I was feeling guilty I was also getting even more excited. 
            Donald's breathing quickened and he soon tensed and came into my mouth.  As much as I wanted to continue and feel my own orgasm, I felt that Jason had spied on quite enough for the evening, so I sat up and rebuttoned my blouse.  I walked Donald to the door and kissed him goodnight as he promised to call me.      
            Still angry with Jason for spying, but still turned on and needing some release, I went to bed and buried my fingers in my cunt, squeezing my nipple and clit between my fingers.  Smelling my own wetness and still tasting Donald's salty cum on my lips, I slammed into an intense orgasm, moaning my passion through my clenched teeth as I bit into my pillow to muffle my screams.  I released my clit and fell asleep almost immediately.
