Step-sibling's morning hangover and sexual encounter with POV

I woke up early with a throbbing headache and a nagging suspicion that I had a wild night I couldn't remember. As I stumbled into the kitchen, my step-sister was already there, looking equally hungover and confused. We exchanged awkward glances before she finally broke the silence. "We had sex last night, didn't we?" she asked, her eyes filled with uncertainty. I confirmed her suspicion, and as the realization dawned on her, she let out a sigh of relief. The morning light filtered through the windows, casting a soft glow on her blonde hair and the curves of her body. I couldn't resist the urge to kiss her, and soon we found ourselves lost in a passionate embrace. The sight of her writhing in pleasure beneath me was enough to make me hard again. I took her from behind, my thrusts echoing through the empty house as I watched her face contort with pleasure. It was a wild, unbridled encounter that left us both breathless and satisfied.
