I crawl into my stepmom's bed and stick my cock in her mouth and she doesn't want me to cum. Part 1 of 2

It was night, I was touching my dick in my bedroom. My sexy stepmom was alone in bed. So I thought what would happen if I went to her bed and asked her to make me cum? She is always very nice to me, I think she won't be offended. Ok I'll go! I get into her stepmom's bed and stick my dick in her mouth and she doesn't want to make me cum. She sucks me for a long time and when she sees that I'm about to come, she slows down, so I can't cum. Her domination is difficult, I want to cum and she stops me!
