Stepmother gives me a blowjob while multitasking on her phone

I was doing some work for my company when my stepmother came in and started to talk to me. She was a big fan of her phone, so while we were talking, she started to play with my dick. I was surprised, because I didn't think that my stepmother would be interested in sex with me. But it turns out, she has a very big cock and she wanted to give me a blowjob. She started sucking my cock while talking on the phone at the same time. I was very surprised by this, because I never thought that my stepmother would do something like that. She was fingering my cock with one hand and sucking it with another hand. I came very fast and I had an orgasm.
