The hand covering her mouth was abruptly withdrawn and fingers and a thumb pressed into her cheeks coaxing her jaws open and before Tanya could react a rubber ring had been jammed into her mouth pinning her jaws wide. As she gurgled in protest and tried shaking her head a thick rubber strap was dragged around her cheeks and jerked tight and buckled fast.

'Nuuhh!'

As Tanya shook her head, crying out incoherently through the ring-gag for them to stop, the men calmly took another rope, fed it behind the small of her back, bound it tightly around one of her arms then drew it back behind her and pulled it tight around her other arm and tied it leaving her arms now all the more firmly pinned against her sides. Looking up at the men and the girl and dragging her wrists and ankles ineffectually against the tight ropes, Tanya felt a surge of fear but also a rush of excitement as after all the experiences of the last couple of weeks she realised that she was in store for some even more demanding time at the hands of these people. The piquant bite of the steel clamps on her labia was as tormenting as it was painful and a dark voice in her head was already urging them to flick on the switch that would send a jolt of electricity into her pussy. The thought alone was almost enough to make her come. Panting hard through the gag she looked at the faces around then realised that she'd stopped trying to scream and shout for them to let her go.

When the first short, sharp shot came it was like a dart that seemed to shoot from her pussy straight to her brain and made her cry out as best the gag allowed. With the second shock Tanya came and as she lay breathless and basking in the after glow of her orgasm, she saw the leader of the gang watching her closely then giving an order to one of the others, the rubber gag was removed, Tanya was left free to speak once more.

'Uhhh!'

The next shock made her writhe helplessly where she lay tethered but other than crying out at the intensity of what she as being subjected to, Tanya made no protest. She tried to convince herself that this was because she knew they wouldn't free her but she knew deep down it was because she was now helplessly aroused and deeply enjoying being forced into such a state of helpless submission and then tortured in the way these people were.

'You want more?'

Tanya turned her head to see the young woman questioning her. Dreamily she nodded affirmatively. The woman smiled triumphantly and said something to the men. There was a moment's pause and then Tanya was trying to convulse against the ropes as the searing sensation of the electricity rippled through her naked body.

'Uhhh...God... enough...please...'

The next shock was more prolonged and seemed too much for Tanya to bear but it had left her pussy throbbing with arousal and very close to coming yet again. Tanya gazed up at the girl, panting hard and whimpering as the ropes bit into her flesh where she struggled so much.

'You had enough?' the girl questioned.

'Make me come... please...' gasped Tanya.

The girl turned to the men and nodded. Two of the men left the bed and turning her head Tanya watched them cross the room to where there was a large box and when she saw what they unpacked she could hardly believe her eyes.

Tanya hoped that they would subject her to the machine straight away, she was so aroused, she was desperate for gratification but her tormentors had other ideas. The ropes that bound her ankles and wrists were all removed and the men hauled Tanya to her feet and dragged her across the room to the padded cross. Her arms were held outstretched to either side of her and bound with ropes against the padded red vinyl. They didn't bother to bind her legs but there was still no way that she could have freed herself and although in moving her from bed to cross the ropes and cords had been removed from her breasts, once she was tethered against the cross the young woman examined her aching breasts and satisfied that they could take more punishment she had one of the men hold each tit in turn whilst she bound it with cord.

'Hurts... stop... please...' Tanya begged, as she watched first her right breast being cruelly constricted with cord. Her pleading was ignored and if the men had earlier bound her breasts achingly tight the girl subjected them to an even more mercilessly tight binding.

With both her tits bound into swollen cones of dark crimson flesh, Tanya could only jerk her arms ineffectually as the tears coursed down her cheeks and she was forced to watch her tits turn from crimson to purple. The young girl was plainly delighted by Tanya's acute suffering and to torment and humiliate her further she pulled her own white T-shirt off over her head and mockingly caressed her own pert breasts, pulling the cotton of her bra cups down under the swell of her breasts to reveal her tits and stroke and caress them as she stood before where Tanya hung bound by her outstretched arms. Speaking in Spanish she then invited one of the men to sample her breasts and Tanya was forced to watch as the man buried his head in her cleavage before closing his mouth on one of her dark nipples, sucking vigorously until it stood firm and hard, glistening with wetness while the man's mouth roamed from the girl's breast to her neck and then mouth.
