Feeling how my preggo girlfriend was smelling made me willing to try something different.. And dirtier. It was summer and we walked a lot that day so before our daily sex I didn't let her take a shower and guided her to out bed. Smelling each others feet and assholes made us incredibly wet! Putting my finger deep inside her tight ass then sniffing it together as I finger her again with my other hand.. she masturbated till orgasm!
