Sena's POV
I was relaxing one weekend when Rika called me and asked if I could come down to her lab and help her test something.
"Hello Rika?" I said walking in.
"Oh good you're here." Rika said pulling my arm "No time to talk just get in here."
"WAH!"
Rika threw my into some big metal closet and closed the door.
"Rika?!" I called out "What am I supposed to do?"
"You just stand still, I'll let you know when were done."
I looked around and the room was so dark I couldn't tell how big it really was.
"Ready, let's get started!" Rika called out.
Is that a loudspeaker?
"HA!" I gasped when two rubber hands shot out and ripped my blouse open "Rika?!"
The hands stared pulling my bra off and yanking on my skirt.
"Rika!" I yelled out when the hands pinched my nipples "What is this?!"
"All part of the process." Rika said "This is a sex machine."
"A what?! OHH!"
I felt something bind my arms and legs.
"RIKA!"
I felt something poking me and when I looked being I saw a dildo was pushing against my vagina. The toy pushed into me and I let out a deep moan.
"But wait there's more!" Rika taunted.
Two more dildos popped out, one quickly penetrated my asshole and another forced its way into my mouth.
"MMMMM!"
It felt so weird to be getting attacked in every hole. I heard something else move and saw two large cups pop out and latch onto my breasts.
What is…
I heard a buzzing noise and I felt a pressure on my breasts. The cups began moving, slowly pumping my breasts. I felt my nipples get sore and suddenly my milk began squirting out.
"HMMMM!"
"Oh look at it all!" Rika said "You young to be lactating but this is so much, look at it all."
"AHHH!" I moaned as my breasts were milked and my holes were pounded.
"Gosh you look so sexy." Rika said "I'm so hot, oh…I'm touching myself Sena…does that turn you on."
I felt more fluid start leaking out my pussy.
I feel so good.
"Sena…I….OHHH!" I heard Rika moan as she orgasmed.
My body kept rocking around as the machine pumped my breasts and pumped my body.
"God Sena there's so much Milk!" Rika yelled "At least a quart and more is coming in."
I can't…hold on…
"OHMMMMMMMM!" I moaned as my insides shifted around Rika's mechanical toys.
The machine stopped and let me go.
"I'd say that was a rousing success." Rika said letting me out.
"I can't believe you did that to me!" I yelled at the naked Rika.
"Sorry, but it worked out." Rika smiled "But now I have another thing I want to test."
"Absolutely not!" I yelled.
"Don't worry you already contributed." She smiled walking over to mess with the machine.
"What did I do?" I asked her.
"You gave me this?" she said holding up a glass full of a white liquid.
"Is that…?"
"It's your milk." She smiled taking a small sip "It tastes delicious."
"How does that help?" I asked her.
"I need to test this." She said dropping a pill into the milk, it quickly fizzled away.
Rika downed the glass quickly.
"Ahh~" she sighed "Tastes sweet."
"What's it gonna do?"
"You'll see…" Rika said "Ohh it's working!"
Rika moaned, arching her back. I gasped as it appeared her breasts were getting slightly larger.
"They're growing!" she yelped "HAAA~"
"Rika!" I yelled out to check on her.
"So much…pressure." She groaned "They're gonna….HAAAAA!"
Rika's breasts quivered and sprayed out milk like a fountain.
"You're lactating!"
"Phew." Rika sighed, brushing her hand over her leaking breasts "that pill was intended to give me lactating breasts for a short time."
Rika hugged me "Thanks for this gift."
Our milk filled chests smashed together, our hard nipple rubbing up against each other.
"I think we're the same size now." I giggled.
"Yeah, two sexy girls with big leaky tits." I laughed back.
Rika softly kissed me before moving my head towards her breasts and popping her nipple into my mouth. I suckled on her breasts while Rika moaned.
"It feels so good." Rika groaned "my breasts are so sore…you're making them feel so good."
Rika pushed me down and I noticed she now had a strap on around her waist, she wasted no time stuffing it into me.
"OH Rika!" I moaned.
"Sena!" she screamed "It's two sided, it's pushing against me too!"
Both of us grinded against each other, our breasts wobbling, still leaking milk. I reached down and began rubbing my clit to further enhance my pleasure.
"I know I'm not as good as Yozura." Rika yelled "but…"
"It's still incredible!" I yelled as the toy pushed against my back wall "I can't hold on!"
"I'm gonna cum to!" she yelled.
Rika drove into me a few more times and I felt my breasts shaking all around.
"RIKAAAAAAA!" I moaned as I felt my insides quiver.
"SENA! I'M CUMMMINNGGG!" she yelled.
Both our breasts shook and sprayed milk around as we climaxed.
"That was intense." Rika smiled "But everything worked."
"Yeah…great stuff." I panted.
"Hey, what do you think about calling Yuki and making her do cosplay for us?" Rika asked.
I picked up my phone.
"Seems that it will have to wait, Yozura wants to go to the movies with me, you wanna tag along?"
"Sounds like fun, I gotta drain my breasts first." She said jiggling her left breast.
"I'll tell her to give us a few minutes." I said licking my lips.
