A middle-aged Arachne with a younger one following behind

You give them a little wave and a wink as you spread your pussy for them to see.

The older one looks at the younger, who grins and nods, before the pair walk over to you. The older Arachne looks over you appraisingly as you try to make a good impression. Seemingly satisfied with what she sees, she nods approvingly, and then speaks to you. "My daughter is moving out of my web tomorrow to make her own way in life. Tradition dictates that I should gift her her first ****, either from my own harem, or newly purchased. Tell me honestly, how would you feel about being my daughter's ****."

As requested, you reply honestly, telling her that you are slightly nervous, but find the girl attractive, and that the idea does arouse you.

She nods. "I would be surprised if you were not slightly nervous, girl, but you seem to not be against the idea of it." She looks back at her daughter, a pretty girl with braided, dirty-blonde hair. "Well, Xyl?"

A fanged grin breaks out on the daughter's face. "She is perfect."

"In that case, I will purchase her for you. Now, away with you, you know the traditions."

Xyl skitters away, though not without a nervous glance back at her mother. Her mother watches until she is out of sight, before turning and entering the slavemarket.

A few minutes later, she is back with a much more stern look on her face, wearing the bracelet which allows her to give you commands on her right wrist.

"Stand up straight, ****, and listen to me." She waits until you are standing normally. "I do not agree with my daughter's foolish desire for a **** who will be as happy with her as she is with them. A ****'s feelings are irrelevant. I am willing to humour her, but I want some insurance. Tell me the names of your parents, and any siblings you have, and how to find where they live."

You immediately tell her what she wants to know, listing off both of your parents, and your younger sister, Lyna.

"Good. If you hurt my daughter, I will personally arrange for all three of them to be captured. Your father will be made a cumslave, while your sister and your mother will be made incubators, one for me and one for a friend of mine, and I will make you watch as we stuff them with eggs fertilised by your father. Do I make myself clear?"

"Yes, er... Mistress? Mistress's mother?"

"You will call me Lady Axi, as despite our current status, you are not to be my ****."

"Yes, Lady Axi."

"Good. Now, hold your legs tightly together, with your arms straight down by your sides."

You obey.

"I believe you humans also have a tradition of unwrapping gifts on special occasions," she says, stepping forward. "Hold that position while I wrap you for my daughter."

Her abdomen lowers, a jet of sticky web shooting out and attaching firmly to your crotch. She moves forward and lifts you off the ground, passing you back until you are beneath her spinnerets. She starts to roll you over, wrapping you in a tight cocoon and leaving your mouth as the only opening.

You are jostled around as she takes you somewhere you can't see, then left lying in the darkness, listening to various things happening on the (presumed) web around you. After several hours, you are fed, more of the bread and bland paste put into your mouth through the gap in the cocoon. Then you are left again. You presume it is night time when all the sounds are replaced with gentle snores, and you try to get some sleep.

You are confused when you wake up in darkness. You are jostled around a lot and it takes a few moments to remember where you are. You finally realise that you have been picked up in your cocoon.

Once the jostling stops, you are mostly upright, with a gentle sway which makes you think your cocoon is hanging from a strand of web.

You are fed once more, before being left to wait to be let out.
