Tentacles Sakura
Sakura glared angrily at Emily as she pointed out just how easily she had managed to convince Sakura to fall into this trap, her anger and annoyance only increased by the fact that the girl was largely correct. Even as Sakura contined to moan from the abuse being heaped upon her by the monster, which obviously saw her as nothing more than a sex toy, her betrayer continued to speak.
"Oh, Chiasm, just so you know", she continued, "those things keeping you from getting inside her are clothes. It's fine if you just tear them off. That aside, the woman you've caught is being rather rude to you, so you shouldn't worry all too much about hurting her. Maybe keep hitting her rear like you were just now...."
The look of anger on Sakura's face intensified as Emily continued her betrayal by giving this "Chiasm" thing more information to aid it in abusing her. Then, the reprecussions of what she had said dawned on Sakura, the anger was replaced by fear of what the monster might do to her, particularly since it now knew of the utter contempt she was treating it with. With the apendages that it possessed and all of the horrible torture devices lying around the room, there was no limit to the amount of pain and suffering it could inflict upon her if it so chose.
However, her thoughts of what may be to come were soon interrupted when the monster suddenly flipped up her skirt, leaving it hanging down her back and exposing her panty-covered rear. Sakura braced herself for her clothes to be ripped off, as Emily had suggested. To her surprise, however, the monster did not do as its "friend" had suggested, instead beginning to move Sakura's legs around, before releasing them and instead grabbing hold of the lace panties. Sakura let out a yelp of pain as the panties, which were now supporting the weight of her lower body, dug painfully into her folds. At the same time, the tentacles surrounding her upper body began to contract and pulsate, restricting her breathing and painfully squashing her soft breasts, leading her to let out another moan.
And, the monster was not finished yet, either. Not content with simply sucking on her asshole, a small, brush-like tendril formed from the larger one, pushing directly into Sakura's asshole. The captive girl let out a loud yelp of surprise as the tendril pushed into her, rubbing against and tickling her inner walls in a manner that was not entirely unpleasant. Entirely against Sakura's will, a small amount of dampness began to appear on the stretched panties as the sensation began to arouse her, her clitoris and nipples beginning to harden, causing her moans of pain to become a little louder as the stretched panties pushed against her sensitive nub.
Sakura's moans became louder still, this time more from pleasure, as a tendril slipped out of the monster's mouth and wrapped itself around her rapidly-hardening nipple, brushing it sensually and covering it with the monster's juices. At the same time, almost as if it were counteracting the pleasure, the monster's tentacles, which had been lightly prodding at and patting her bottom, suddenly sucked theirselves down onto her soft flesh, causing her to yelp once more from the shock. A more pained hint came to her moans once more as the suction cups pulled painfully on the flesh.
Sakura felt degraded, abused and frightened. The sensations she was feeling were not entirely unpleasant, but they were most certainly unwelcome. Her eyes began to tear up as she moaned from the pleasure and pain she was in, her body being tormented and pleasured in a variety of ways. She wanted this to stop, before it went any further. Deciding to change tack and see if she could appeal to the more human side that the monster apparently possessed, Sakura addressed her once more, this time more politely.
"Please, Chiasm, please stop!" she said, almost in tears, her speech interrupted by moans of pleasure and pain, her speech constrained by the tendrils wrapped around her. "I don't want this. Emily, please, ask her to stop."
