you were sitting on your bed reading till all of a sudden your friend little sister came in the room and sit besides you, she looked like a baby so you didn't mind her but then you felt a touch on your shoulder, you turned and faced her, you followed where she was pointing her finger till... her pants a big ass bulge between her legs

"unf!"

she handed you a note wich said "sorry if im hard im probably just thinking about my brother and his fat ass, you can help out if you want, but I'll masturbate alone if you don't want to"

She gives you a relieved smile before she slides off your bed and onto her stomach with her ass in the air and her face buried into the pillow, clearly not entirely comfortable with exposing herself like this but trusting that you won't do anything bad. Her soft moans fill the room as you begin to stroke her hard little ass through her panties, feeling the head of whatever it is she has growing larger and more sensitive with every touch.

She lets out a sigh of relief and spreads her legs wider, giving you better access to play with whatever it is growing between them. You can feel the heat radiating off of her skin as your touches become more focused and intense, driving her closer to the edge. Her moans grow louder and more urgent now, muffled only by the pillow as she tries to keep quiet in case someone else hears her.

She arches her back and moans even louder as you pull down her panties, revealing the smooth flesh of her shaven pussy and the sizable cock she has hidden between her legs. The sight is enough to make your heart race and your own erection ache for release. As you continue to kiss and touch every inch of her body, your fingers find their way back to her sensitive folds, teasing and pleasuring her until she's practically begging for more.

She gasps and writhes beneath you, arching her back off the bed as you work your magic between her legs. Her hips buck upwards in rhythm with your hand, seeking out more contact with your touch. She moans unintelligibly into the pillow, losing herself to the pleasure coursing through every nerve ending in her body.

She screams your name, her body shuddering as she comes hard around your fingers and cock. Her walls clamp down on you, milking every last drop of pleasure from your invaded orifices before finally releasing you with a satisfied groan. Beads of sweat roll down her forehead and cheeks as she catches her breath, still quivering from the intense orgasm.

"Oh god..." she whispers, looking up at you with dazed eyes. "That was... that was amazing."
