Stepson is sad, stepmother blows the pain away

I cum into my bedroom and what do I see? My stepson is lying in my bed - nude again, of course. The young boy really drives me crazy. But this time something was different. It was actually his anniversary with his girlfriend, which he wanted to celebrate. However, she had a "headache", which of course he didn't like at all. How do I get him back on his feet now? I have an idea. A blowjob from his stepmother should be a good start. Just blow away the pain - just like before. And to make sure I get something out of it, he can then fuck me good and spread his cum on and inside me. Win-win situation ?
