When I read the old video "How To Give Your Girl A Screaming Orgasm" I got my idea about mom teaching teen cunnilingus and old cock riding techniques from there. As a matter of fact I use the same theories that mom used in the video to teach my daughter how to give a good blow job to her boyfriend every night. In fact our sex life is so much better than it ever was since I started using these techniques on my wife, now we have couples' cunnilingus sessions every night and it really feels good..
