POV - I should feel guilty but it's hard to with such a smile on my face. I wasn't expecting her to creep into my room after her night out with the girls, she just flung my bedroom door open and dragged off my boxers, no care in the world for step-dad overhearing. Sucked me, fucked me, gushed all over me and then held me in tight when I was about to cum. She had no guilty conscience over heading back to my step-dads bed leaking my cum down her thigh.
