Put your all into it

You lower yourself in front of Xyryx, and when the signal is given, you dive in with gusto. You run your tongue up her labia, delivering a kiss to her clit as you reach it.

As your mouth works hard, your arms encircle her waist, where the humanoid and arachnoid parts meet, holding you up as you extend your legs underneath her. Obstructed by your overfilled womb, you find it difficult to identify your target as you reach a leg up and trail it gently across her underside.

Then you find it.

Near the back of her spider body is a narrow slit. You carefully push your toes into the tight gap, and start to slowly slide your foot along the length of it.

Xyryx's moans, already significant due to your efforts with your mouth, rapidly grow far stronger.

Your foot is suddenly ejected from the slit, pushed by a rapidly extending ovipositor. Taking a deep breath, you bring your other leg up, gripping the thick shaft with both feet. You are now hanging underneath her, supporting the full weight of yourself and Mistress's eggs with just your arms and the tenuous grip of your feet. You won't be able to to keep this up for long.

You redouble your oral efforts, and start to pump your legs in and out, sliding your feet along the length of the ovipositor.

Xyryx lets out a loud scream as your face is drenched with her juices. A spray of liquid also hits your nethers, shot from her ovipositor as she came. As the orgasm subsides, you drop your feet back down and gently pull your face out of her muff, before collapsing to the web beneath her, panting.

Once you've caught your breath, you check how Mistress is doing with Tal, but it seems they are already finished, with Mistress in a similar state to Xyryx.

"I would call that a draw," Mistress says, "but I think we are both winners. Your **** is very good at that."

"Yours pulled something I have not seen before, but intend to train my own slaves to do."

"The benefits of letting her take initiative. With a little more training, she might become even better."

"Good work, Tarissa," Mistress says as she leads you home.

"Thank you, Mistress."

"You did not win, but given the skills of your opponent, and that you managed to draw with her, I do not hold that against you at all.

"I saw what you were doing with your feet, and believe me I want to experience that for myself, but it seemed to tire you out, so I will allow you to perform some less strenuous tasks for now."

"Thank you, Mistress."

"Now, once we get home, you are to go and prepare dinner for yourself, and then feed the incubators."
