Me too!! BIG-TIME!!!!! Grrrrrrrrrrrrr!!!!!!!I like lifting the ball sack up, so I can see my wife's vaginal opening stretched out to accommodate the BBC.
Then laying the flat of my tongue on the burgeoning muscular pump-bulge of the thrusting erection of her lover to pleasure him more intensely and let him know I'm loving him doing her----as I always do when my beautifully huge-cocked young black buddy is fucking my ex.
Then lifting his uptightened ball-sac to watch his thick youngman spunk welling back out between the jerking root of his ejaculating cock and the grossly overstretched rim of my ex's vagina.
Oh my oh my, does that get me going!!
