Don't move and be her rag doll.

Spider girl uses her legs to wrap around your butt and bring you closer to her. You’re now pressing together. Through your pants, your large bulge rubs between her legs which sends a sensation through you that you can’t exactly describe.

The back of her other hand slides down your cheek. It’s smooth and you melt at the touch. You wonder where she learned this? A romance movie? An interactive erotia story? When you realize that she’s about to go in for a kiss, you move your head back. Normal girls would take it as some sort of hint, but spider girl’s hand reaches your neck and forces your head towards hers. Your lips meet as you let out a gasp. She sucks on your top lip while you try to escape. Though this is undoubtedly the hottest thing that has even happened to you, you think a more preferable partner would probably be... Human?

The spider lady is just too strong. You give in to her kiss, ignoring the sharp fangs of each of her cheeks that dig into your own. You fear that any moment the rest of your theorized friends will wake up to see this. Well, maybe if they did they’d all respect you a little more and not knock you out and leave you alone for anthropoid spiders to seduce you. Again, just a theory.
As you kiss more and more, a suction cup sound releases from both of your mouths. You think the sound just aroused you even more.

You open your eyes to see her staring at you with her strange blue and black eyes. You push on her with both of your hands, but end up cupping her firm breasts. You don’t know if everything is going bad for you today or if everything is going right.

Spider girl breaks the kiss and with both of her hands she grabs your shoulders with her yellow hands, letting go of her web. You gasp, hoping that this girl knows what she’s doing. It’s a good thing that the spider girl isn’t as heavy as she looks, not that she looks heavy or anything.

The girl’s sharp (confirmed) feet move up high to the waist of your pants. With her legs she tears the sides of your pants. Slowly they fall down the tree landing on a branch far below. When she sees that stripping your pants has been a success, spider girl crawls up your body. The girl must trust you, because easily you could push her and she would fall off... Wait. That's true!
