She can't control her power

Inari focused her power, trying to summon a Fox Fire that could set the female ablaze. She felt the power starting to gather and launched it. But it only took a moment for her to realize her mistake. The energy that struck the female Arachne had no form and couldn't be seen by the others in the clearing. But the effects were noticeable to Inari. The female's cheeks flushed even more and her pussy was suddenly soaking wet even though Moseph's cock hadn't touched her and she was still clearly afraid of what she was about to do. Then realization dawned on Inari: She was a deity that could increase fertility, and that was exactly what she had done.

As the female began to lower her waist and take Moseph's cock into her, Inari screamed and tears rolled down her cheek. The female looked up in alarm and stopped for a moment, but the male barked some kind of command before stepping in front of Inari and grabbing her head. His own waist silk was gone and a large cock was not in her face. Before she could react he began pushing the impressive member between her lips and into her mouth. Although Inari couldn't see the female and Moseph, she could still hear their grunts and moans as the female resumed her work. Inari knew that fighting the cock in her mouth would just get her killed so she remained still and continued to cry silently as the male began slowly fucking her face.

Moseph had tried to struggle when this ordeal had first began, but with both of them wrapped in the Arachne's silk, there was no way to escape or fight back. Inari was still too new to this reincarnation to be able to fight with magic and Moseph was too weak to use his. When the Female approached him, their goal became apparent and he hoped that if he was compliant, that the pair would leave after they were done. But he hadn't counted on how much watching the female start to mount him would hurt Inari. Or how much it would hurt him when the male began using her mouth for his pleasure. He kept the pain and jealousy locked inside as the female began slowly riding his cock. She was nervous and he was amazed when he felt her hymen tear. She gave a soft cry but for some reason she was panting as if she was in heat. After a few moments of slow riding to let her body adjust to his size, she placed her hands on his shoulders and began riding him frantically. Her large, purple tits bounced in his face as she moaned her joy at having his cock. The bite of lust venom had made it so Moseph was enjoying the ride just as much and he too was moaning. But when one of those glorious tits pressed too close to his mouth, he took the chance and began sucking on the nipple, causing the female to squeal in delight.

Inari couldn't help herself. Even though listening to them moaning was killing her, it was also making her insanely horny. Add to it the dick in her mouth and she felt her pussy growing wetter and wetter. Before she realized she was doing it, her tongue was swirling around the cock invading her mouth and her lips were wrapping around it tighter. The male gave a husky moan and patted her head before slamming his cock into her mouth harder and faster and she bobbed her head as best she could to meet his thrusting. Soon the sound of her slurping on his cock was almost as loud as Moseph and the female's mating.

Inari was lost in pleasuring the cock in front of her and didn't hear the female's scream of ecstasy as she came on Moseph's cock, or his return moan of triumph as this pushed him over the edge. Moseph's cum filled her little pussy and she quickly climbed off him and reached back to her spider half to collect some silk. She quicky used it to seal her pussy shut before making herself another waist covering. She blushed and gave Moseph a kiss on the cheek before turning to look at the male and Inari. The male was now hamming his cock into her mouth and Inari was cooing happily. Suddenly he pulled out and aimed his cock right for her face. With a deep groan it began firing its cum onto her cheeks and across her tongue. When the beast finally stopped her face and hair were covered in his seed and he was panting hard. Inari blinked in surprise for a moment and then suddenly stiffened and seemed to pass out. Moseph called out to her, worried that the male had done something to hurt her but she didn't answer. The male walked over to him and used one sharp leg to cut partially through the silk binding Moseph. It would still be a struggle for him to get free, but it was now manageable. As he started tearing at his bindings, the Arachne turned and went back into the dark forest.
