What do you get the person that has everything? Customized porn of their partner, obviously! Actually, It’s a pretty good gift for other people too. ;)
A good friend of mine is really into forearms (it’s a thing) and one of her partners is a weight lifter. For my friend’s birthday we collaborated and made a photo triptych of her partner rolling up the sleeves of a dress shirt.
I’m super happy with the result. (She seemed pretty happy with it too)
