It’s perfectly fine. F1 students are allowed to (and many do) go home on vacation. Why are you even bothering to apply for a B visa? It’s unnecessary and You don’t need it until you complete your study program.
As long as you’re in valid F1 student status, you can travel in and out of the USA for as long as you like and as frequently as you like. During the summer break it’s assumed you will enroll for the following semester so far as your program has not ended, and hence your F1 visa is still valid and able to be used to travel in and out of the USA.
During vacations you’re allowed to live in the USA or anywhere you choose. This is not a problem at all.
