Terramar tossed the Playgriff magazine he had been reading aside on his bed. His head hit his warm pillow and he breathed a sigh of relief as he observed the pool of semen he had squirted out, coating his penis and the mattress in his cum, his claw still clutching his rock-hard cock. He thanked Novo he was in his fathers home atop Mount Aris right now and he had gone out long enough for Terramar to masturbate. Otherwise, the illustrations in his magazine would be too soaked to see underwater, and his cum would be floating around the room! That would be hard to wipe up...
Speaking of which, Terramar realized he needed a cleanup before his dad got back. He glanced at the clock. "I should be fine." He stretched as he sat on the side of his bed. "Dad won’t be home for another hour!"
Flying out of his room, Terramar tossed his magazine onto the pile he had stacked up on the living room ottoman, which he would put away just as soon as he cleaned himself up. Soon, he stood in the shower, taking off the crystal shard around his neck and setting it on a hook nearby as he turned on the water.
Feeling the relaxing sensation of the water washing over his body, Terramar closed his eyes and embraced the wonderful feeling of the water cleaning him, washing the dirt, cum, and seaweed from his body. While it cleaned him off, he moved his hands through his green hair. Man, was it ever dirty! He’d have to get himself one Tartarus of a haircut soon!
Rubbing over his belly and down his back legs, Terramar paused as he thought he heard the sound of the front door opening. He was considering pausing his shower and stepping out to check who it was, but decided not to. He was probably hearing things. After all, his father was gone for the day. The only other person it could be was...
"Terramar?!" The familiar excited squealing nearly made him fall over. He steadied himself with his wings, looking in horror as he saw his sister, Silverstream, standing before the open shower door. "Silverstream! Wha-what are YOU doing here?" Terramar asked, trying to cover the view of his bulging cock from his sister.
"We had some f-free time after school, so I-I thought I’d come visit Dad! But I-I didn’t think YOU'D be here! And when I walked in, I found THIS!" She held up a Playgriff magazine, the same one Terramar had just masturbated to. "What is THIS? I didn’t know you were into this stuff!"
Even under the cold water, Terramar felt his face burn with embarrassment and he felt his manhood rising as he admitted. "Alright, yes, that’s mine! I just like reading those when I’m alone, okay?"
He thought she’d be disgusted, but instead Silverstream laughed. "Seriously? You’ve been jacking off to ALL of these? How lonely ARE you?"
"Well, I’m sorry, but it's hard to find a girlfriend for both land AND sea, you know!" Terramar sighed. As he reached to turn off the water, though, his sister removed her own necklace and jumped into the shower with him.
"What are you-?" He protested, but was silenced by her pressing her beak against his and entering her tongue into his mouth in a wonderful kiss. He cried out and fought it at first, but eventually softened up and began kissing her back. Well, this was a little strange. He didn’t know his own sister had such feelings for him.
"What was that about?" He asked when their tongues disconnected, feeling a little sad by the new empty feeling in his mouth. "Well, you obviously needed it." Silverstream said, rolling her eyes. "Yeah, it’s weird, but you need to know what actual sex feels like, you know?"
Terramar smiled. "Yeah, I guess I DO." He wrapped his long arms around his sister and picked her up, bringing her out of the shower and into his bedroom, them sharing another passionate kiss in the meantime.
Laying his sister down on his bed, Terramar noticed that splotches of his excitement from earlier were still on his bedsheets. He hoped his sister wouldn’t notice, and she thankfully didn’t as she rolled onto her stomach and spread her legs apart to reveal her beautiful ass and pussy. "Come on. You know you can’t resist me anymore!"
Terramar positioned himself behind her, brandishing his erect dick. He rubbed it’s tip against Silverstream's pussy, making her moan and clutch the bedsheets. Then he breathed in and stuck his cock fully in her ass, pushing it as far against the tight walls as it could reach, until his balls hit her knees. The pleasuring screech that escaped her mouth encouraged him to press on, thrusting himself in and out of her butt lovingly, feeling hotter and hotter with each passing second.
Fucking his beautiful sister felt great, but also strange on Terramar's part. What would his parents think if they found out? They’d probably ban him from both worlds! He’d have to go back to living on that tree branch!
Luckily, it didn’t last long. With Terramar fucking his sister repeatedly in her ass, and Silverstream masturbating herself, her fingers dipping into her wet vagina, it wasn’t long before she came, cum pouring out of her pussy uncontrollably, while at the same time, Terramar let out a squawk and emptied his balls, coming inside his sister's butt!
The siblings moaned and collapsed on the bed, breathing in each other's cum. "Man, That was amazing!" Silverstream gushed after a minute, before climbing off the bed and heading for the door. "Alright, I'm going back to school. Say hi to Dad for me."
"I will." Terramar nodded. "And Silverstream?"
"Yeah?" She looked at him.
He smiled warmly. "I absolutely love you."
She smiled back, stretching her butt and flashing her vagina, still dripping wet with his hippogriff semen. "I love you too."
