So, I am in a pickle. My gf is finally giving me alone time tomorrow. Since we are home so much with everything going on. I am looking to find a provider for fun tomorrow. But here is the second issue. I am on call for work. I'm in IT its all remote work. I don't know if I could do a full session. I never know if I will get a call or not. So, I was thinking a make out session and blowjob would be good since it wouldn't be a super long session.  

I'm probably just being selfish and should wait until I have more time. Not sure. Just really need some fun.

I gotta agree with MyaMichelle here.  You are NOT paying for the activities done; you are paying for the provider's time and company.  Which means what you do while together is irrelevant.  Whether it's just _____ or everything but the kitchen sink, the rate is the same.  At the same time, if *you* need to end early, whether because you chose to or because your work called, that's still on you; there is no rate cut.  You booked an hour of her time (or two or three), you pay for that time.  Besides, a 22-year-old whippersnapper, which I was when I first started hobbying, can fit everything and then some into 30 minutes, let alone 1 hour.

OP, your post is unwarranted, sorry.  Either book a full hour and accept the possibility of your work interrupting you, or wait until you're off call and book then.

I never said anything about paying less. I just meant. Would it be rude if I cut the session short. I might just have to stop in the middle.  

Anyways, I did not schedule anything.
