Sisters Clock Is Ticking

You've been called into work and we both know it's ovulation day. I beg you to stay at least long enough to have sex and you lovingly agree. My clock is ticking and who knows when we'll get the chance again? I need to get pregnant! Please, before you go to work, fill me with your nice long dick and shoot a creampie deep into my cervix. Let's try to make a baby!
