After enduring a full month of abstinence for pregnancy efforts, my wife coldly rejected me... The next morning, I heard my mother-in-law's lewd moans from the next room! Peeking through the door crack, I saw her - a body like a woman in her 20s with pure white skin and massive J-cup tits - masturbating wildly! My pent-up cock snapped, rationality destroyed! I slammed my rock-hard cock into her exquisite pussy and fucked her raw like a beast! "Mother-in-law! You're way too erotic!!" Overwhelmed by bottomless lust, I completely forgot about my wife and creampied her again and again! The gradually addicted mother-in-law begged, "Forget about that child... Cum inside me!!" I pumped load after load of thick semen from a month's abstinence deep into her womb!
