Twisted blowjob training

I am so nervous. I have a date with an older guy... old like daddy... I don't know anything about pleasing a man... Luckily, mommy steps in and teaches me how to... she said we are an open minded family and she brought a huge toy and showed me how to suck a dick. This is weird as fuck. To have a dick in the mouth... but I guess I'll have to get used to it....
