I seduce my step-sister-in-law and have sex with her while her boyfriend is away

After a steamy encounter with my friend's girlfriend, I found myself back at her place, eager for more. Though her boyfriend was around, the allure of her voluptuous curves and luscious lips was too strong to resist. As we lounged on the bed, our hands roaming freely, the boyfriend casually strolled in, oblivious to our growing arousal. Seizing the opportunity, I swiftly took her to the bathroom for some private, passionate lovemaking.There, under the shower, we indulged in each other's bodies, her ample curves and I, lost in the ecstasy. Once the coast was clear, we returned to the bedroom, where I took her from behind, relishing her full figure. As we switched positions, she eagerly took me in her mouth, her expert skills leaving me breathless. Finally, we settled into a rhythm, our bodies entwined in a dance of pleasure, culminating in an explosive climax that left us both satisfied.
