Were you an anime character, you would no doubt have a sweatdrop three times your size running down the back of your head at this moment. Unfortunately, you aren't, so you have only your furiously blushing cheeks to show your embarrassment as you approach Nidorina's vagina. Once you're up close to it, you tenuously stroke the slit with your hand, causing her body to shudder as she let out a soft coo. You look up at her own blushing face. "A-are you sure I can enter through here? I think that-"
"Just... Don't worry about it." Nidorina replied, looking more red in the face than blue, "And, if this is making you uncomfortable, then I could always-"
"No, no, it's alright. Let's get this over with."
You gently pry apart the slit and climb inside, immediately gaining a feeling of warmth as you enter Nidorina's womanhood. Echoing through the walls you hear her moan in pleasure, and saw the imprint of her hand rubbing against her crotch. After about a minute, though, her lust abated, and she stood up and started walking somewhere, causing you to stumble and land on the sensitive tissue. "Hey, careful!" she said with a giggle, "I'm kinda ticklish down there!"
"Sorry." You gingerly got up again, moving slowly and deliberately away from her labia. "Um, if I may ask, where are we going?"
"To my home. Maybe I can find something there to help you, but I don't have full confidence in that. In the meantime, just... relax, I guess."
You figured Nidorina had considered saying things more... racy than relaxation. Behind you, you noticed the entrance to her cervix, which seemed to be pulsing in time with her heartbeat. Would you consider climbing in it, to see what you could find deep within this girl? Or were you going to exercise better judgement and not risk Nidorina's wrath?
