Any suggestions on some fun sex games we can play using items around the house (not looking to go out and buy anything).

One idea is indoor, strip volleyball:

You will need: balloon, long-thick string, clothes, two consenting adults

What to do: You clear your living room floor. Tie string across middle of living room, separating it into two halves. Each one of you takes an opposing side. You use the balloon as a volleyball, and play away. For every point scored, an item of clothing comes off. Once one person is naked, you can resort to sexual favors that have to be done to continue the game. Play however you want, & have fun.

I put this as an example, so you can know what I am looking for as far as a game goes.
