I just hung up the phone with my brother, he wants to come by to see the plants. He watched the house for me when I was travelling a few weeks ago, so he knows what's going on.
"Hey Larissa, I have something to tell you about," I said as I walked into the living room. She was naked, as usual, and sitting on the couch watching TV.
"What's up?"
"So we're not the only ones in my family who know about the plants. My brother house-sat for me, and he's in on it. He wants to come by this afternoon and spend some time with the plants."
"Your brother? That's going to be interesting."
"Yeah, it's a little weird. It's very entertaining to watch him get off with the plants."
"We can watch? Awesome!"
"I have been, though the plants did me too, so I guess he's also watching us."
"Fair enough."
Matt showed up after lunch. He walked into the house to find Larissa naked in the living room. I walked in to say hi, also naked.
"Why is everybody naked?" Matt asked as his eyes jumped from Larissa to me, and back.
"I'm a nudist," Larissa answered, "And I talked your sister into joining me. Take off your clothes and get comfortable."
Matt looked over at me, I nodded yes, it's okay. He pulled his shirt off, then undid his pants and yanked them off. He had a pretty obvious erection happening in his boxers.
"It's okay, we don't mind erections," Larissa said while looking his way. "I take it as a compliment."
Matt pulled his boxers off, Larissa stared at his cock. I have to admit, it's a pretty big one. I never really thought about it before, but it has to be around nine or ten inches. I might have been imagining things, but I thought Larissa looked a little hungry for it.
"So Matt, have you tried the plants in the backyard?" Larissa asked.
"What plants?"
"We found a map that your aunt left behind, there are some much bigger and more aggressive plants back in the woods," she said.
"What do you mean by more aggressive?"
"Well, they pretty much take control of everything. They grab your ankles and wrists, then they have their way with you."
"Fuck, that sounds nuts."
"It's a little unnerving, but the sex is amazing," I said.
"Do you think I should try it?"
"Sure, why not?" Larissa said. She got up and took Matt's hand. I followed the two of them out into the backyard. We don't need the map any longer, we know where the spot is. We walked back to it, and the three of us stood still.
"This is Alison's brother, Matt," Larissa said. "He would like to meet you."
The largest flower opened first, then the rest. Tentacles made their way towards us, wrapping around our wrists and ankles, spreading us wide. The tentacles pulled Matt backwards and into a flower next to the largest one. They spread his legs, and two tentacles worked their way up his legs. The first attached to his cock, sucking it in and pulsating on it. The second sucked his balls in.
"Ohhh fuck," Matt moaned. His cock slid in and out of the tentacle, the other seemed to be munching on his balls. I watched fascinated, but was reminded where I was when I felt a pair of tentacles coming up my legs. A penis pushed into me, and a mouth sucked on my clit. Larissa moaned loudly, I looked over to see her getting the same treatment. The three of us were in the control of the plants, and we were all in heaven.
The wet slurping on my clit was driving me mad, I almost didn't notice the three tentacles coming towards us. Three penises, one for each of us. They slipped up between our legs, and they pushed in to us from behind at the same time. Each of us grunted in surprise as they forcefully entered us. More and more tentacles appeared around me, licking me and sucking on my nipples. They seemed to be everywhere. It was sensory overload. I felt like I would be orgasming soon as I watched Larissa and Matt pushed to their limits.
The tentacles on Matt moved him onto his back. They held him just off the ground, somehow, they were all working together. Larissa was moved above Matt, then the tentacles slowly lowered her onto him. The tentacle sucking Matt's cock let it fall out, then it wrapped around his cock and directed it into Larissa's pussy.
"OH!" she moaned loudly as Matt's cock entered her. Matt moaned as he pushed all the way into her soft pussy. It was about that moment that I lost it, I began orgasming. I couldn't help myself.
"FUCK YES!" I moaned. The penises and tentacles worked together to get me off. Every inch of my body was immersed in pleasure. It was fucking insane. I could hear Matt and Larissa getting off nearby, but I was barely aware of what they were doing. Larissa was riding his cock as the two of them came, their moans of pleasure mixed with mine. Fuck, I love having my pussy eaten, and it's even better when I'm getting fucked at the same time. Holy fuck!
After a few more minutes, we were all finished cumming. The plants cleaned us up, licking all the plant cum from us, then retreated back to their flowers. Larissa was still sitting on Matt's cock, probably limp inside her by then.
"That was fucking crazy," Matt said.
"We need to do it again," I suggested.
Larissa climbed off Matt, letting his cock slide out. She took it in her hand, then bent forward to kiss it. Matt squirmed and smiled at her.
"Soon," Larissa added.
