Between Nylonlegs And Smotherbox

My nylonlegs spread above his head while his head is caught movelessly inwards the smotherbox. Its the flawless seating position to squeeze out his breathing air with both of my arms without grace! In between I allow him to have a break. But not because he deserved a break to breathe, but because I wanna exploit his relief! I wanna brutally take his new won joy by pressing my hands again on his mouth and nose, and that time Ill increase the pressure and make it last even longer!
