Things my Ex-wife would do.

The one thing that my ex-wife would do to me, and it drove me wild, was play with my cock when I was going down on her.  That made me so hard.  I would tweak her nipples a I licked her clit and she would begin playing with my cock with her feet.  Running her toes up and down the shaft and teasing my balls.  The more I licked and sucked her pussy, the more frenzied her feet would work.  When I worked my tongue down to her asshole, she had my dick between her feet stroking it with all she could.  I always fought the urge to cum, but I made sure she came before me.  I could tell when she was close by the rhythm of her hips and how wet she was getting.  That and her talking dirty, begging me to shove my cock into her and fill her pussy with hot cum.  I loved to torture her at that point, and when she started to say "I'm cumming", I would stick my finger up her ass and suck hard on her clit.  She would begin to convulse, her asshole clinching my finger as she came.  Her feet pushed together, trapping my cock.   I would begin to fuck her feet when she did that.  When I was close to cumming, I would shift my body, straddling her upper body and trap her arms while I stroked my shaft and came on her face.  She would try to lick my cock, but I would tease her by keeping it just out of reach until she begged me to let her suck me until I came in her mouth.  I do miss her at times...
