Your best friend with benefits is knocked up. You're not the father, so you've respectfully kept your distance since she became pregnant - until she calls you with a pregnancy emergency! The fertility pills she took to become pregnant have the side effect of making her uncontrollably horny throughout her pregnancy. She needs cock NOW and you are happy to provide it. Pregnant women turn you on, even though you're not ready to be a dad yourself. But since your friend is already knocked up, there's no harm in blowing a load inside her. To the surprise of you both, her belly immediately begins to expand with a SECOND pregnancy. Still, the knocked up slut is insatiable, and your dick is still hard, so she keeps riding your cock, working out load after load. Her tits begin to expand as well as her belly, growing heavy with milk. The fucking only stops when she is too top-heavy to keep going and must fall back on the bed to spend the rest of her hyper pregnancy on bedrest while you do your best to quell her out-of-control hormones with your cock.
