<human>: My girlfriend and I have been dating for about 11 months, the first 9 of which we were always together and I got to know her parents well. We are currently in a long-distance relationship and we haven't seen each other in about a month and a half. She is coming up to visit me at my college and her mom won't let her go alone. We are both in college and her parents insist on one of them coming and babysitting. My girlfriend is paying for her flight and the hotel. I am paying for everything while she is here. It's not like we are asking them to pay for us.

We will be busy all the time with couple activities and when we aren't we will obviously want some alone time, which we won't be able to get. This is frustrating to both of us as we both have a high sex drive, especially with each other. Her parents do not know we have had sex and we are not really wanting to tell them we do. Her mom is basically coming up to be birth control. 

Basically what I am asking is what can we do to tell her parents they really don't need to come and it is more of an annoying waste of money than anything else?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My girlfriend is coming to visit; her mom insists on coming specifically to cockblock. Need some advice on what to tell her to let my girlfriend come alone.
