I know I shouldn't have gone in there, but he was late for work again. Like every other morning, I walked into my stepson's room to wake him up. I did what I always do I pulled back the blanket to get him moving but today was different. He was lying there completely naked, and his huge morning wood was impossible to ignore. I stood there for a second, my heart racing, and then I just couldn't help myself. I reached down and started stroking him. One thing led to another, and before I knew it, I was cheating on my husband right there in his bed. I needed that hard cock so badly. I climbed on top and started riding him, feeling every inch. He reached for the bottle and started pouring warm oil all over my big tits, and the sensation sent me over the edge. I started bouncing my huge oily tits like crazy, giving him a show he’ll never forget. I’ve never had such intense, amazing orgasms in my life. I didn't stop until I was covered. I kept stroking him until he couldn't take it anymore, and he finished with a massive cumshot all over my tits. Now that we've crossed this line, I don't think I can ever go back.
