Ok, heres my problem. I'll be at my girlfriends house, and we get into it, she starts giveing me a handjob and I start fingering her and rubbing her tits, were makeing out during all this by the way. Well I'll get her wet, then I get her to cum, but I never cum like I do when I jack off. I mean I do a little bit, but when shes done im still hard as hell, and didn't fully cum. And shes doing it nice and good, but her hand is down my pants, that wouldn't stop me from fully cumming though? Wtf is wrong here. Little help plz. Also sometimes shes starts grinding on me when were lieing on the couch, shes on top of me grinding on my dick, but im still won't cum all the way. HELP PLEASE, thank ya
