I argued with my wife and went to the guest room, to my surprise my sister-in-law arrived and we started talking... She has always been quite flirtatious but this time she came on too much to me, she came into the room with an anal plug stuck in her ass and started teasing me when she found out I was arguing with my wife... It was really hard to resist but the slut managed to convince me and let me penetrate her huge, delicious ass until I came inside it!
