I'm pregnant and my husband cuckolds me with my sister-in-law in front of him

Being pregnant and full of desire, I never thought that seeing my husband fucking my sister-in-law in front of me could turn me on so much. The tension begins when she arrives at the house and her chemistry with him is felt in the air. I settle in, watching every movement as I touch myself slowly, unable to stop seeing how he grabs her tightly, how she moans and how they both get carried away by the moment. My breathing speeds up as my body responds on its own, enjoying every detail, every thrust, every moan. The scene gets so hot that I end up participating, touching myself harder as I watch my husband use it to vent. It is a forbidden fantasy that becomes reality, full of desire, family tension and a morbidity that does not let you breathe.
