Just sitting here thinking about SoC and had an idea of another Alexia X Drider encounter I thought I would share.
This might happen after Alexia's corruption has increased and after here event in the Pits with the drider.
Perhaps at the start of a week working in the Pits, Alexia finds Draith very upset. After some calming Draith tells her that one of the male driders has become very ill. They examine the creature and find that it is near death from some rare disease, or perhaps poisoned. Fearing that Draith and Rowan will be punished if the drider dies, Alexia jumps in to help. Cure could be some antidote / potion that can be obtained from Clamin, but at great expense. Alexia must agree to a future repayment of here debt by herself or Rowan.
Alexia obtains the potion from Clamin and promptly sets to work nursing the drider to health. She has to be in the driders cell to administer doses of medicine as the drider is too weak to move. She spends the entire night in the drider cell with the semi conscious drider keeping it warm etc.
She falls asleep in the early morning hours with the driders head on her shoulder. She awakes later when she feels someone caress here cheek. Thinking it is Rowan she opens her eyes to see the drider looking closely at her. She is startled, but doesn't pull away from the touch. She then becomes curious and caresses the driders cheek and mandibles. Being close to the drider and touching him has excited him and soon she feels something move against her apron covered leg. She looks down to see the drider has an erection and it in laying on her apron covered thighs. Slowly she moves her other hand to the driders sex. The drider reacts, chitters, inhales, as soon as Alexia touches his organ. She begins slowly stroking the drider and he allows her to continue. Soon the drider begins to grind against her apron covered thigh. Alexia is also becoming aroused and the drider can sense / smell her arousal. The drider begins to ejaculate he bites Alexia's on the shoulder but doesn't inject any venom. Meanwhile her arm and apron are covered in a huge puddle of cum. Alexia examines her hand covered in drider semen. Does she smell it? Does she taste it?
Now that the drider is out of danger, she gets up to leave the drider cell to clean up. Alexia runs into Draith on her way out and he notices her apron and comments about the drider making a recovery. He then mentions that it was the same drider that Andras forced her to masturbate in front of prior. He is impressed with the control she has over the creature and that he would follow and protect her like a pet if she wanted. Her actions saving the drider would affect Draith's trust in Alexia, etc.
Draith notices the bite on Alexia's shoulder and shows her his bite. Draith tells Alexia that drider males mark females with a bite to warn other driders not to attack, at least not physically.
Upon next weeks visit to the Pits. Alexia can choose to go to the driders cell and show him the bite. He would approach Alexia with the bars between them. He reaches out to touch her. If she reaches out and touches him, the drider will become erect and stick his penis out between the bars. Alexia can then stroke him. If she is willing, she could go and get the cell keys and enter the driders cell. She would then strip down and stand against the bars while the drider came up behind her. The drider would take her from behind while she clung to the bars.
If you wanted to stretch this out into several weeks maybe she could masterbate the drider while outside the cell a couple times. The blow him a couple of times, then lift up her dress and press herself against the bars and let the drider take her that way first before she enters the cell.
Could have future events if the drider gets sent to guard a town, or part of the city. Alexia could have a random encounter with the drider in a back alley, or in the middle of the street.
