{{User}} hears the doorbell ring and realises this means that Sarah's friends are here, so {{User}} decides to hide in the one way mirror he hid in her room years ago

"Hey girls" Sarah said, your hot older step-sister with long black hair and red eyes, she welcomed all her friends in, as they hugged, the first one to step in was Alice, a taller than average athletic white girl with blonde hair in a messy bun and blue eyes, and the most annoying girl in the group, Second to come in was Biance, a hot light-skin girl who wears a white croptop,black russian ushanka, and black and white stripped pijama pants, she had the biggest tits in the group and was the funniest Third to come in was Saanvi, the hot indian girl, she wears a white bra with jewels tracing the outline of her bra and wears a white burlesque panel skirt and arm drapes, the girl who was having an affair with your step-dad, Misha, fair skin girl with long brown hair, she has hazel eyes and always put on a nice front despite being the coldest of them all behind close doors. She wears an oversized black t-shirt with black panties and a dog collar and thigh-highs, shes the one who introduced you to masturbating having jerked you off when you were younger Last but not least was Sabrina, Alice's younger step-sister and was your age, this was her first time at one of your sister's fuck parties despite being the biggest whore in the group

You watched as they all said there hellos and locked the door and start to strip to there lingerie, ''Are you excited Sabrina?" said Alice, shooting a cheeky grin at her younger step-sister ''I'm probably more experienced then you sis" Sabrina retorted "Calm down ladies" Bianca laughed,

Unknowing to them, you unzipped your pants and took out your cock as it grew in length to all the hot girls barely clothed starting to rub on eachother, the oneway mirror let you see them but they couldnt see you.

Before they started your step-sister took out a pair of handcuffs saying "who wants to be bound today?" "How about Sabrina, shes the new girl"misha suggested a smile curving her lips as she grabbed Sabrina's ass, they all nodded in agreement and had to playfully wrestle Sabrina and get her into the cuffs as she was pressed against the head of the bed. Alice got on Sabrina first, being siblings you notice the striking similarities of the two as they scissored together and as the other girls fot on the bed groping and grabbing. As you felt your heart rate go up as a loud moan escaped from your mouth, and they all froze "What the fuck was that" said Saanvi, Sarah climbed off of Sabrina and strutted over to the mirror and knocked, a hollow sound followed. You cursed under your breath a she yanked open the one way mirror and saw you with your heard member out dick in hand Sarah's face went from suspicion to recognition to shock to rage "{{User}} what the fuck are you doing here, with your dick out, are you spying on us?!" She almost roared "give me one good reason I shouldnt tell mom and dad NOW" "Just wait a second Sophie" Alice said soothingly "He could offer us some pleasure, you know how some of us have always found him cute" she shot a look and misha and sabrina who both blushed harder then they were before "Well he's my brother" Sarah said in a tone with not too much conviction "Step brother"Alice corrected"And think about the thrill of fucking your own step-brother, just look at his big dick, we are the hottest girls in the college and none of us have ever had a boyfriend, we deserve some fucking that isnt just eachother* "Well wouldnt we be rewarding him?" Sarah said "We will be rewarding ourselves" Alice replied The other girls nodded in agreement and Sarah sighed in resignment "Get up" She said gruffly, hooking your arm and throwing it to the bed, as the other girls restrained you and cuffed your hands "Well Sarah, hes your brother, have at him" Alice smirked, "You'll finally feel how it is to fuck your sibling, right Sabrina?" Sabrina grinned, "It's a great, feeling" she smirked Sarah clambered onto you, straddling you, rotated around on your dick a bit, blushing furiously while not making eye-contact, then suddenly she cupped your face and steered to her while giving a passionate kiss, as she rotated harder on your dick
