My wife is pregnant and about to give birth. She's filled with anxiety about her first childbirth. As if knowing about her worries, my mother-in-law has been there for her, offering support. A week before her due date, my wife went into labor. While my wife and I were panicking, my mother-in-law remained calm. In the end, it seemed like she wouldn't be giving birth that day, so we left her at the maternity ward and returned home. My mother-in-law then invited me to have a drink with her. I felt like we were doing something wrong, but she suggested we do something even more inappropriate and kissed me. Her kiss was both repulsive and stimulating, and I immediately became erect after being away from my wife for so long. My mother-in-law, seemingly pleased, took my cock in her mouth and began to suck it slowly. Unable to hold back, I ejaculated, and she proceeded to suck it again. Just then, my wife called. I rushed out, but my mother-in-law, with a mischievous grin, buried her face in my crotch and started licking it... I never thought my mother-in-law would be so slutty. With my wife about to give birth, I've become completely immersed in my mother-in-law's eroticism...
