Was i wrong to trick my Mom into Headscissors?

Is it wrong i tricked my Mom into Headscissoring me?

I've always loved the idea of a headscissor. But never knew how to go about getting one from a girl. So, one evening after swim practise, i came home and started complaining about a sore neck/jaw. It was just my and my Mom at home. It was a hot night so i was just wearing my usual briefs. I asked if she'd press her hands on my neck and she did. I asked her to use her biceps and she did. So i plucked up the courage and asked her to use her thighs...Just to try and squeeze the tension out of my neck. She did. I was writhing about in my underwear, eyes nearly popping out. It was awesome. But is it wrong i tricked her into it?
