Enjoying caring for Carrie

Trent and I waited till after my parents call before we began to touch Carrie again. We did not want any reason for Carrie to get upset.
But my biggest obstacle was the cameras. But I told mom that there was a power surge and it's been spotty at reconnecting.
She didn't have a problem with my cousin Trent hanging out with us as "one more set of eyes wouldn't hurt".
After I hung up the phone Carrie was more relaxed and she didn't mind when Trent and I say on either side of her on the couch. Trent gave Carrie her tablet to distract her from our touches.
I grabbed one puffy nipple and squeezed and pulled it. Trent grabbed the other. We pulled, pinched and twisted her nipples why we watched pork on TV. Both our clocks were hard but we hadn't pulled them out again yet.
Trent moaned and said to Carrie "look Carrie you want to sit on my lap? He patted his hands on his thighs.
I still rolled Carrie's hard nipple between my fingers.
I encouraged Carrie. "Go on Carrie. Sit on his lap. You can still watch your tablet on his lap."
Carrie smiled and then stood up. Trent pushed his shorts down and guided Carrie's hips onto his. I jumped in the floor on my knees and moved Carrie's legs on the outside of Trents legs.
Tent positioned his cock to between her wide spread pussy. I told Carrie to sit back. Carrie wiggled her ass cheeks and Trent's cock slipped inside my sister's pussy.
I made sure that Carrie's tablet was on her favorite cartoon then I moved closer.
I took my fingers and started rubbing her clit hard as Trent rocked her hips back and forth.
"How's it look dude? " Trent asked.
"Fucking hot" " You want pictures?" I asked.
"Yeah yeah, here's my phone. No face pics though" he said as he handed me his phone.
"I got you bra". As I took his phone and started snapping. Some upclose showing how tight her pussy was stretched around his cock. Some videos of her pussy coating his shaft. A few of his fingers pulling her pussy hair.
Carrie began to grunt. But Trent kept rocking her hips back and forth. He moaned and rolled his head back "holy fuck this is fucking amazing" he hissed.
Carrie started grunting more.
"What's wrong with man?" Trent asked.
"I don't know. She may have to pee, or she may feel good. She's fucking retarded so I don't know" I explained.
Carrie grunted even more. "Fuck she's Cumming" Trent yelled.
"What? How do you know? " I yelled back.
"Her pussy is throbbing, this feels insane" he moaned.
I got the phone closer to her pussy and sure enough her pussy juice started dripping down his shaft. Carrie was grunting constantly as she started to rock harder. I reached up and started sucking on Carries hard nipple while squeezing her other nipple. I started rubbing her hard erect clit again. My fingers brushed against Trents cock.
Tent yelled "I'm gonna cum. Brah I'm gonna cum in her again man"
Then I heard him moan and he thrusted his cock deeper and knocked Carrie off balance and she dropped her tablet. I bit her nipple harder than I should have. And she started whinning and grunted over and over.
Trent's cock was still shooting cum onto his stomach now.
I stood up and pulled Carrie to try to get her not to spiral.
I think it worked as she pushed her face into my chest and started sucking her thumb.
"My turn next" I said to Trent....
