Ever since I first met my older brother's wife, I've had feelings for her. When my brother and his wife came back to visit our parents' home, I couldn't help but turn my attention to my sister-in-law. Her sweet smile captivated me, and at 25 years old, even through her clothes, her perky breasts, round, plump ass, and smooth, thick thighs were impossible to ignore. An uncontrollable desire to see her bare skin grew stronger inside me. I started secretly watching her bathe and peeking in on my brother and her during their intimate moments. Seeing her moan lewdly drove me wild with excitement. Eventually, my sister-in-law gives in to my persistent feelings. "Just once," she says, before kneeling in the kitchen and taking my cock into her mouth. Overcome with ecstasy from this forbidden act, I erupt deeply inside her mouth. Later that night, with the rest of the family asleep, we finally give in to our sinful desires and have sex.
