Nice expressions Yuma! i did it raw with my GF and we both felt spiritually very fulfilled, i guess i can imagine your feelings too, thanks for reminding me of my unforgettable times with her
I once had sex with my Japanese gf in an open air onsen, compared with salty water i think onsen water tends to be more lubricating .. and of course, you've gotta be able to stay hard inside 40 degrees hot water !!
