Rebecca walks into the room dressed in a sexy dress as her master has directed her to - she has a sexy short dress with stockings and high heels. He kisses her on the lips as he eases the shoulder straps of her dress over her shoulders causing the dress to fall to the floor. Rebecca stands in her bra, g string and stockings with heels. He takes a knife and cuts her bra straps tearing it from her body. He massages her breasts sucking each nipple deep into his mouth and lickig them until they are errect. He puts his hands in his pockets and pulls out a pair of nipple clamps with long string. He quickly attaches them to her nipples causing her to cry out. He walks her over to a table bending her over it and roughly tears the g string from her body her wet pussy is clearly visible showing she is clearly aroused even though tears run down her cheeks from the painful clamps. He takes a bottle of lube squirting it liberally inside her anus sliding a finger inside and starts to finger her. She begins to grunt as he gets quicker. Soon the lube is seeping from her bottom and he knows she is ready. He walks her over to a symbian machine and asks her to remove her shoes and to straddle it. He assists her as her legs are trembling scared by the two dildos that protrude the Symbian. He gentally lowers her rubbing her clit as the dildos start to violate her vagina and ass. She gasps as inch by inch they fill her. With one final push down on her shoulders her body betrays her and she screams out as her groin joins with the body of the Symbian. He roughly pulls up her ankles and secures them to a strap at the side of the symbian and starts to feed another strap around her thighs. He pulls the straps until the last hole is visible and feeds the needle through to lock them in place. He checks and she is unable to move an inch. Just to check he slides his hand between her legs and pinches her clit hard - she immediately screams out and ties to lift herself off the Symbian but it's pointless - she can't move her lower body. Rebecca feels the string attached to her nipple clamps move and opens her eyes to see him threading it through a metal ring attached to the floor. He loosely ties it before going out of sight. Rebecca starts to wonder if he has left her when a rope is put over her head and pulled down around her neck and pulled tight. Her hands instinctively move to her neck to remove the rope he quicky cuffs them and attaches each one to ropes attached to the wall. He pulls the neck rope tight and ties it off against the wall. Her body is the. Forced forward and the rope from her nipple clamps is pulled very tight. She cries out and starts to sweat at the pain and eventually has to lean forward to ease the tension on the rope and ease the pain in her nipples. She quickly realises that as she does this the noose around her neck tightens and she starts to struggle to breathe and the pain from her nipples is intensified. She hears a laugh and the voice of her master tells her she must balance between the pain of her nipples and the need for oxygen. He tells her that he test will now begin. With that a leather hood is placed over her head. She is now totally in darkness and can hear buttons being pressed. Immediately she feels a low frequency vibration start between her legs which travel up the dildos. Her master immediately starts to pump the attached bulbs inflating the dildos until they are noticeably causing her to struggle. She machine is set to run for an hour - increasing in intensity and speed. Her master watches as her body starts to thrash around, her breathing getting increasingly desperate as the reduced oxygen starts to make her feight he turns the Symbian to full speed she starts to grunt and pant as the rope tightens , her pussy and ass are on fire and her nipples numb. Rebecca starts to get dizzy as a massive orgasm builds - she is gasping for each breath and she starts to cum he body thrashes uncontrollably and her veins in her arms are clearly visible as she stretches the arm ropes trying to pull off the noose as she starts to go pale with lack of oxygen the orgasm hits her - she now is on the verge of asphyxiation and is forced to throw her head back to take the pressure off her neck. As she does this the nipple clamps are ripped from her nipples she slumps against the wall behind and passes out.
