I agree with you. Next time you are on top and having trouble getting it in just ask hubby to give your lovers cock a good suck to get it good and slippery and have him guide it into your ready and waiting pussy. He might also enjoy giving your anus a little bit of tongue when you are in this position, It also opens up the opportunity for him to run his tongue up your lovers shaft or to hold and caress his balls as he ejaculates into you. Myself, I love it if she tells him to hold my balls and feel my seed pumping into her this way
