A great home improvement we made a while back was to fit a twin size bath, so now there is no more worries about who has the tap end! I hated always having the tap end, now the taps are in the middle, we have a combi boiler so no more tanks that run out of hot water anymore and we are happy.
Did a great deep bubble bath the other eve, got the candles burning, and we both sank in, ahhh, my wife sometimes brings in her waterproof vibe, it makes a deep humming sound right through the tub, I love her feet up on my knees while she buzzes away too.
When we got dried, I like to towel her off, she immediately gets both feet up on my shoulders/face and teases the hell out of me with her toes, jeez it's not very long before I am sent flying into orbit!

Hmm, I prefer to use bath partner as a cushion! course feet would be further away in that case...
