Arapocolypse (Part XII)

I have no idea how to do this, and to be honest I don't want to, but Maddie is very eager.

“Come on! The feeling in your tummy will go away if you do this, at least for a little while.”

I sigh and try to mimic what she did earlier, rubbing the odd-feeling spot and fingering myself. It doesn't seem to be working, so I begin to push and do it harder; I can feel something. The ball in my gut loosens and feels like it's coming apart. Something rather unpleasant begins to come out of what I think is my cervix, and coaxing it out with my fingers a number of tentacles similar to Maddie's sticks out of my vagina, albeit there's a few more and they're noticeably thicker. Maddie stares at them. They're personally revolting, but the feeling in my gut is gone, and it feels nice to let them “hang out,” so to speak.

“I'm impressed,” she says, “now come here!”

I scoot over to her and pull her closer. It feels too weird actually moving these things on my own, so I put them inside her by hand and wrap my legs around her. Maddie lets out a quite moan, and I begin to actually move them around. It feels nice, but it's far better receiving than giving. Maddie grabs one of my breasts and begins to suckle on it, and it feels much better than I was expecting; but I didn't know what it'd feel like. She suckles harder as I move inside her, and her hips begin to move. Maddie takes her mouth off my breast and looks at me.

“Your milk tastes like chocolate,” she says with a half-moan-half-giggle. She squirts a bit on her hand and puts it in my mouth. To my surprise it does have a vague, slight hint of chocolate. She switches breasts and grabs my sides. This goes one for a few minutes before she suddenly lets out a yelp of sorts and slumps back, placing one hand on her stomach and using her other arm to prop herself up. I partly retract my tentacles and tuck them in the rest of the way, wriggling my hips and thighs to get them all the way back. I can feel them inside my gut, but it's far less noticeable now.

Maddie somewhat catches her breath, and mutters “I had no idea it would be that good” as she stretches  and leans forward, “I didn't know it could be be that good.” I ask her if I did anything different from what she did, and she says that she might tell me later. Why wouldn't she just tell me now?
