My sister opened her eyes to find herself chained down on my bed “…..what the fuck Matt?!” she yelled as she saw me standing next to her with my muscular arms holding a whip in my right hand and a gag ball in the other. she saw i was shirtless showing off my 6-pack and tanned skin to her.

“whats wrong sis? don’t like being tied down by a man?” i teased her, knowing that by now she loved being pinned or helpless around me.

“you better untie me bro unless you want to be in serious trouble!” she threatened.

“empty threats again sis? they never work……” i held the whip up after putting the gag in her mouth “now….its time i showed you who your master is!” with that i cracked the whip across the floor making her jump(as little as she could) in fear of the whip.

“y-you better not touch me with that!” she said trying to keep a straight angry face when it was obvious she was scared.

“or what sis?” i asked bravely, not scared of her doing anything. she did not answer ,so i continued “well if your not going to do anything, i will!” i grabbed her shirt and pulled a knife off the computer desk next to me, then cut her shirt down the middle as she took in air from a gasp not expecting me to tear one of her shirts like that.

I held tightly onto the blade as i traced it over her belly slowly making sure not to cut her. “like it baby sis? knowing i hold a very painful tool in my hand…..and i control whether you feel pain or not right now……” she glared at me as i talked, then i moved the knife slowly up towards her bra, and traced the fabric around her tits as the blade lightly got caught in some of the fibers and cut them as it continued on.

I sighed loudly suddenly “I’m bored playing with you…..” i stuck the blade under the front of her bra and cut the middle strap connecting the two. her bra flew open making her tits flop out and jiggle a little. she blushed as soon as this happened a light red color. “aw sis you look so cute like that!” i said to tease her and she let out a low growl at me as i smiles looking down at her tits.

I laughed a little loving when she growled like that. its so cute because she tries to act tough, and resist the things i do to her, but she loves it. since neither our mom nor our dad were home i realized we did not need the gag ball, so i took it out, the second i did she yelled “fucker!” at me.

“ooh, sis…..how naughty of you! you don’t call your master a fucker!” with that i took my whip and cracked it across her tits once on each making her arch her back and squeal with pain. “you okay sis? did that hurt? not too much i hope…..you have a lot more in store for you……” with that i leaned down and played with her soft tits.

Beckie knew she was defenseless and without any means to stop me at all. mom and dad were on a second honeymoon. their 23rd year had been ruined by a freak tornado, so they left me in charge. being the oldest, even if only by two minutes, they considered me the better leader. so they left me and my fraternal twin sister home alone for an entire week.

Beckie was now starting to feel her pussy get wet as she realized that i could do whatever i wanted and she could not stop me no matter what she may have wanted. ad she found herself arching her back to the feeling of my hands.

“In fact i haven’t even started yet!” i said enthusiastically as i felt her nipples harden and her tits get firmer as i leaned down and sucked on them slowly.

“M-Matt!” she said while blushing still. she was arching her back trying to get more of her boobs into my hungry mouth. i started nibbling on the tips at a soft bite, she sighed lightly, then i bit harder suddenly and she let out a loud gasp and whimpered a little.

Beckie was not even sure why she was so turned on. normally she would not give in like she was. she normally put up a lot better of a resistance. we had not had sex in over two weeks since dad got laid off from work. all i could do was tease her all the time. so she figured that was why she was acting this way.

“do you like it baby sister?”i let go of her tits and whispered softly in her ear, then i moved my hand slowly down to her belly and lower still.
