Carrie steps over him and decends to a schoolgirlpin (SGP) on his chest, let him feel her immens weight and soon she moves further and sits on his mouth.
Now the nose right in fron of her pussy he must inhale all the odors from there... sitll a little bit of oxygene... with some spices ;-)
The its finish with breathing, she moves further and covers all of the face, her flesh seals properly.
For sitting mor comfortable, she streches out her legs, more comfortable for her more weight and presssure for him... he tries to survive under the mountain of flesh.
