I am super heavily pregnant! Days away from giving birth and everything aches! One student must stay behind as he got some work wrong. My back aches so i get him to give me a back rub, he confesses he has always had a thing for me and the feeling is mutual. This sends me into labour! I return the back rub favour by jerking him off and then riding his cock, i inform him he must never tell his parents. I finish on his cock by having an orgasm and contraction.
