Rude Awakening

I was awoken the next morning to the feeling of someone crawling into my bed. That someone wasted no time in removing my shorts and exposing my sopping wet pussy. It was then that became mildly aware that I was in heat, but it didn't REALLY hit me until I felt myself be rolled onto my back, my legs spread and a nice, thick, long, warm cock slide to the hilt inside me, eliciting a nice long moan of pleasure from me. The cock pulled nearly all the way as my brain started to gather focus and it wasn't until it thrust roughly back in that my eyes finally rid themselves of the morning haze and I looked up to see Mara between my legs, a bright smile on her face that oddly put my at ease a bit, but she was still my new dad. "Dad?" I exclaimed.

"Morning, sleepy head. Noticed you were in a bit of a need, so I figured I'd help ya out," she greeted, not stopping for a moment, instead, she started to build up a good rhythm and it was really driving me nuts. "I must say, you have a great pussy. So nice and warm. Almost as good as your mom."

"But, you're my dad," I protested weakly.

"Stepdad," she corrected.
