From behind!

"Bend over, baby," Said Finn, trying to pretend he was confident about this.

Marina did what he said with a smile. She turned around, facing the headboard of the bed, and leaned forward to rest on her elbows, sticking her ass in the air and wiggling it while looking over at Finn. "Come on then, silly!" Marina joked.

Finn smiled at her. Totally naked, ass in the air, joking with him... Marina was the most amazing thing he'd ever seen. He sat up and ran his hand down her back. "You're fucking perfect, you know." He said softly to her. He leaned forward and kissed her neck, making her moan.

He crawled around to place himself behind Marina. The sight of her thick ass in the air was incredible. She had spread her legs just right in order to make her ass cheeks spread apart a bit. Finn rubbed her ass with both hands.

"You can spank me if you want," Marina turned and said.

Finn rubbed her ass a little harder and squeezed it before slapping one cheek gently. He was amazed by how her ass moved when it was slapped. He grabbed her ass and jiggled her cheeks, just observing what it looked like. Then he slapped her several more times, each time a little harder than the last, until he had left a faint red handprint outlined on her body. With each slap, Marina involuntarily jumped, but she also moaned and was slightly rocking her whole body forward and backward, as if she was encouraging him to continue.

Marina's body was very inviting, and Finn couldn't resist leaning down and licking her from her pussy to her asshole. He couldn't believe what he was doing, but he loved it, and according to the sounds Marina made, she did, too. He focused on licking her puckered asshole for a while longer. Just a few hours ago, he probably would have been disgusted by the thought of licking an asshole. Now though, he couldn't resist tonguing Marina's.

Finn finally pulled himself away from rimming Marina, and as he sat back up, he slapped her ass with both hands before moving forward and taking his cock in his hand. He slowly slid two fingers into Marina's pussy as he stroked his cock. She was incredibly tight, to the point that he had to push for a bit to get his fingers inside of her. Marina didn't wince or pull away from what Finn imagined would hurt, though, so he continued to finger her.

When Finn took his fingers out of Marina's pussy, they were soaked. He looked at them for a moment before using that hand to stroke his cock. Once he was finished lubing himself up with Marina's juices, he held her hip with his left hand, and lined his cock up to her pussy with his right. Finn rubbed his cock along the puffy lips of Marina's wet pussy, making her moan softly.

"Slide your cock into me, baby. I want to feel every inch of you." Marina purred.

Finn obeyed, pressing himself against her opening. He pushed and pushed, sure that he wasn't going to fit, when suddenly, the head of his cock popped inside of her. Both Finn and Marina seemed surprised by this - Finn grabbed onto Marina's body with both hands as if to steady her, and Marina gasped before giggling and looking over her shoulder at him, smiling. He took that as his invitation to continue, and began very slowly pushing his cock further into her, pulling back a little, and then continuing forward. He did this until the entire length of his shaft was inside of Marina, enveloped by the warmth of her body.

"Fuck..." Finn groaned, balls deep inside of her. "This is amazing."

Marina laughed. "You like it, huh?"

"Fuck yes, I do!" He laughed, too. Then he started to move his hips faster, thrusting harder and making Marina close her eyes and bite her bottom lip. Seeing how much she was enjoying his cock made Finn even hornier, and he began to really drive his cock in and out of her with much more ****, making her big tits bounce hard. Marina was now moaning loudly, and Finn wondered for a moment if Dean would be able to hear her in their room next door.

Marina reached down to rub her clit while Finn plowed her from behind. Finn could feel her muscles clenching as she finally came, moaning his name. It wasn't something he expected, and it pushed him over the top. He was deep inside of her with her pussy throbbing on his cock when he came, too. Thick ropes of cum filled Marina up, and when Finn pulled out of her, a string of cum stretched from her entrance to the tip of his cock. He quickly and awkwardly grabbed his phone from the bed to snap a photo.

"How's it look?" Marina asked.

Finn grinned and crawled forward to show her.

"Wow. You better send that to me so I can rub my pussy thinking about this later..."

Finn texted the photo to Marina. While he was at it, he made sure to send it to Dean, too. Marina rolled over onto her side to face Finn.

"We should get to bed, we have an early day tomorrow." She stroked his cheek with the back of her hand as she spoke. "I need to go take a shower. You okay with cleaning yourself up and heading back to your room? I'm afraid that if you stay we won't get much sleep..." She giggled and leaned over to kiss him.

"That's probably true," Finn laughed. "Yeah, though, it's cool. I need to get some rest... If i'm exhausted tomorrow my parents might start asking questions."

Finn and Marina kissed each other again, with Finn gently rubbing Marina's nipples, before saying goodnight. Marina went into the bathroom to have a shower, and Finn tossed his pajamas back on. He grabbed his phone and practically ran back to his room.

Finn unlocked the door to find his startled brother. Dean was lying on his bed with his phone in one hand and his cock in the other.

"Dude, take that shit into the bathroom next time." Finn joked.

"I'm not the one sending my brother pics of my cock giving a girl a creampie."

"Technically I had already creampied her before the picture was taken, that was just the aftermath. Plus, I'm not the one jerking it to a pic of my brother's cock."

"Fuck you." Dean laughed, getting up and heading to the bathroom.

Finn didn't take his own advice, and while Dean was in the bathroom jerking off to his brother's masterpiece, Finn got his phone out and jerked off to the photo, too.
