Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

Just imagine you're my gym instructor then suddenly you put your

What will you do if you were my gym instructor..
