A couple in their room get into some naughty fun. The guy removes the girls panties and gives her a diaper to wear.
Together they have some sexy diaper fun which makes the girl cum in her diaper, which the man removes for her.
They now both diaper each other and have an afternoon of sex in diapers.
I have to agree with you about the Bambino Quadro. I sleep on my side mostly and they have made for a lot more dry sheets in the morning. I also have to agree about the tranquility there ok but no where near the quadro.
