BBK Hood & Smellbag Masturbation

Well, i have also tried out a long time period in the bbk + smellbag. the mask isn't that heavy like the twinset and also has no inside gag, but the air breathing through that rubber lungs is very fast hot and used. so there is a great effect of breath control in it and finally the rubber aroma is excellent. just found out there is a zipper on my rubber lungs to put some smelly stuff into it... i guess this function is mostly for guys who have to smell all day the used panties of there mistresses. my panties are rubber, nothing so smelly for that at all ????????????
