I'm only staying with my gf cause she gives the best bj
Are her blowjobs really the only reason you stay with her?
I don't know, maybe I liked the time we played sex games and of course how much we make out.
It's pretty awesome that she can please you that well but being with her just for the sex is really unfair to her. You would be better off just being friends instead of leading her on just to keep her around. When she realizes she isn't happy anymore, or that you are not committed to her, it's going to be a really bad time for both of you.
I know what I'm doing. Ah yeah me and her used to make love-sex last fall and that winter.
It sounds like your girlfriend is enjoying herself as much as you are, so maybe things are going well for you.  However, she should be aware that this is mostly a physical, impassioned relationship.  If she is expecting long-term commitment, then you may need to talk it over.
