What a fuck?! Step son risky putting cock in step mom's mouth! Step mommy gets oral creampie

I had a bad back and my husband wasn't home. It was good that my stepson agreed to help me. I lay on his lap to give him a massage and at one point he pulled out his huge dick. I was shocked! He put it in my mouth and started fucking me at the same time as he touched my firm tits. Fuck, he cum in my mouth! Ewww....
