Lusting After You (GirlxIntersex)

The only person being there for Kiana in life is her step mom for 2 years now and maybe one day she's there more than she expected to.

Kiana feels her relationship being shifted further from her mother and closer to her step mother. A heat slowly began to raised between the two in which they just can't stop.

"It's me, Kiana... I-I really, really need you." I declared,
I took a gamble and climbed on her.

"Your mom is right there." She expressed her surprise.

"Please just take me." I moaned on her lips, breathless. I eased my ass up to pull her underwear down to her thigh, grasped her cock, and carefully sat on it.

"Oh my sh-shit..." She grumbled as my moist pussy swallowed her whole. Instead of waiting for my pussy to get used to the length, I began to rock on her and almost screamed out in agony.

"You're going to injure yourself... You're still new at this."

"I don't mind; I'm horny and I need you." My finger traced down her lips before resting on them.
I tried to rush it, to get the first round over with, but something twist in me and I collapse on her. It hurt so much, but I want it all at once.
I felt her lift my upper body, my cock still deep within me, and rush me into the restroom. She turned on the light and pressed the buttons to lock the door behind her.

She positioned me on the counter where I had made a mistake and opened my legs wide, causing her cock to sink deeper.

"Oh my god... Don't pull it out quite yet!" I demand, my voice booming around the room.
She placed a finger on my lips and pointed to the room.

"Sorry." I whimpered in agony. But when a 12 inch cock is buried deep into my womb, being silent is the least I can do.
