Same here,My wife is Filipino.She is 40 & very high sex drive.Everytime I fucked her I could tell that she wants for longer duration but I cum so quickly.She was very tradition,but I did introduce a 8'' cock toy & anal plus along with getting her watch those amateur threesome while we fucked a few years ago to her,at first she was very uncomfortable but didn't rejected and her pussy discharge more lube(that was a good start & I knew she would be fine with the idea taking another cock in our bedroom).After a couple of years of trying,she is now enjoying sucking my cock until I cum in her mouth while I use toy fucking her pussy(her favorite is fucking the beer bottle while sucking me & swallow my cum,not sure why but she admitted she crave for my sperm sometime).Once she has the bottle moving in & out from her cunt she would suck any guy & swallow every drop of it and finally she admitted that she refer better if someone fucking her either her ass or pussy from behind while sucking me.unfortunately we didn't have any chance yet to try on the real guys even that she finally agrees to invite another couple of guys to joint in where they could continue to fuck her right after I cum in her.
