Watch me ask my step son if i can get his opinion on something.. my panties seem to be really smelly recently and was wondering if he could sniff them while im wearing them.. I explain its completely natural thing to do... I then rub my finger along my lips and ask my son to sniff my finger... Mmm smells dirty dosnt it... How about mummys arsehole i finger it and give it to my son to sniff.... You seem to be getting an erection.. its only right i help you out i get you to rub your tip around mommys stinky bumhole.. and then i stroke your dick till your white liquid spurts all over mummys satin nighty... Your such a good boy
