Bitchy pregnant 19yr old girlfriend wants to get fucked

I have a 19 yr old girlfriend that is 8 and half months pregnant. Seeing her nude and smoking really turns me on. Today was typical, she came out of our bedroom naked and smoking. She was raging on me for some stupid thing I did or didn't do. She wanted to get fucked again. We go to the bedroom, and she practically rips my clothes off and starts sucking my cock. When she gets it hard enough to fuck, she says she wants her pussy eaten. So, I eat her pussy while she smokes. I climb on top of her and cock slap her a little. We fuck in all kinds of positions. When I'm about to cum, I decide it's time to give her a favorite snack which is my hot cum. I grab her by the hair and shoot my load into her mouth.
