Pregnant teacher wants you to cum on her belly

I think that I'm alone but I turn around and see you, my student. What are you doing here? Oh, judging by the large bulge in your pants I think I know. And well, being blowed out pregnant and not feeling so great about myself, I'm flattered. And I'm turned on. So I decide to give you what you want (well, almost). I encourage you to take your cock out and start stroking it for me. Eventually I take off all my clothes and instruct you to cum when I finish my countdown and I want you to cum all over my big round pregnant belly!
