Swallowing your potential babies can be a great chance for her that her mouth is the only mouth that comes near your dick. That being said, she might even thing about being the only one in your bed for a very long time.
She knows that taking care of you by cooking delicious meals and giving you a relaxing foot massage is one way to keep you, but she also knows that the best way to keep a man is by satisfying him in the bedroom.
Sorry, but it’s the truth. I haven’t yet met a man who thought about making a girl his girlfriend because she was so good at giving foot massages. However, I met quite a few guys who told me with excitement that their current girlfriend is the best lover they ever had.
When a girl gives you one blowjob after another and swallows every drop of your semen, you can be quite sure that she wants to keep you.
