Das schlafzimmer der stieftochter

One of my guys has come over for some fun.... and for some reason, I quite fancied giving him his regular seeing to in the stepdaughter's bedroom. The problem is, I'm forever changing and washing the bedding from our bedroom, and the hubby's noticing that I'm washing bedsheets for our room every day, but everyone elses only get a weekly wash. Didn't wanna tell him it's cos our sheets are usually covered in stranger's cum stains!
