Ben was too busy daydreaming about Gwen. Teenage hormones drove his emotions into hero mode as he pictured his cousin body in his mind again, and he realised with a start that he was making eye contact with his cousin, Gwen had come over a visit his room to see him in the RV with max we're gone shopping.

His cock began to rise in his pants, and he whimpered as he realised.

What was wrong with him?

Nothing in the real world was getting through because his brain was already sliding back to Gwen warm embrace. He recalls they slept together last night, was a mistake.

What had she done to him? He can't stop thinking of her.

What was she going to do to him?

Gwen hadn't touched him since that first time experience. When he had woken up being by a naked Gwen, her wet pussy nestled between his penis... So many emotions had flown through him in that second. Shock. Fear. Of Grandpa and his parents were going to kill him.

What he did was wrong but he can't get Gwen out of his mind.

Her nice tits.

Her cute butt.

She wiggling her ass and feeling the pussy pulse softly against his skin.

He had squeezed it, run his hand up and down... it was difficult let go. After minutes of thinking he was going to cry, moving into the shower to wash Gwen cum from his body, aching all over, before having the most pleasure time in his entire life.

He didn't want to see her just yet.

But realised Gwen still in the RV, he heard heavy creaks on the floor. When she eventually arrived his heart began to pump with excitement. She had on a pair of shorts and a wearing his white shirt that look good on her.

"Hey doofus." A sheepish grin was on her face.

"Hey... what's up Gwen?" The young hero legs crossed tight together as she sidled over to him, bringing her lips close to his ear.

"... Nothing just to see you doofus," she whispered, her lips grazing his ear, "how are you?"

He squirmed at the warm touch. "Fine Gwen, let go gross face!"

Gwen had giggled, lightly brushing his back as he breathed feeling her tits hit him. He let out a soft whimper. "That's what you didn't say last night cousin."

"Um... whatever cousin... I uh... I gotta go..." Ben made a clear of the kitchen, running to his room. He took a few moments in his bedroom to try and calm his breathing as he wanted to play hero to clear his mind. The watch we're into his hand, as he was about to go hero but then he thinks about Gwen hands touching him. 'Ben no Dude, last night was a mistake and go ask the dweeb last night was a mistake, but I can't, Gwen is too hot-...' The words caught the hero throat. He knew what it felt like on what he did was wrong but he can't help to get his cousin out of his mind.

'Men grandpa max is going to sent me to plumbers school or worst...' The young hero slumped, looking over at the bed that was a mess, and the pieces of Gwen panties were on the floor.

Her clothes from yesterday.

The messy sheets.

He could still smell her body, sex everywhere, Gwen performed and he closed his eyes shut, rubbing his head, and thought for a moment. 'I had sex with the annoying dweeb...' He remembers as he had bent her on all four for minutes than she was on top of him with sweating body's on her beautiful skin. "Ugh...no I'm doing it again." He felt sick feelings Gwen insides him but it were good

A few minutes went by, until he clean his room.

'Just.. get rid of all my cousin panties... Stop thinking about it.' He picked up a red panties, where sweat had went on it. 'I can't believe I'm picking up Gwen underwear. I... shouldn't ask her to come in here... just do it yourself...' He sniffed it. "Okay... okay just... just relax... don't sniffed her underwear, it's wrong Ben." He put the underwear on his desk and hopefully to play hero will clear his mind. So he can beat up some aliens and the people will cheer him on. Just as he was about to go hero, the sound of the RV bedroom door knocking froze his body.

Knock.

"Wh... who's there?"

Gwen voice came out. "Ben, it's me. May I come in?"

His heart began to pound. "U-um... I-I'm a little... busy dweeb..."

The voice paused. "Like no your not Doofus... open it or I'll break your door."

"Um... uh... o-okay..." The door opened, and Gwen walk in, with a smile on her face.

"God your so annoying." She bending over as she did so, and Ben eyes betrayed him with a look to her cleavage, and he could see all the way between them and down to her red bra and beyond.

Her body loomed over him for a second.

"I'm not ... dweeb..."

"Yes you are!"

She made to leave, speaking over her shoulder as she did so. "About to go hero?"

His face went pale. "UHhhhh.. n-no! Just... just checking... my watch I wasn't going hero!..."

She turned from the door as he look at his watch, and stopped him by placing a hand on his cheek, a worried look on her face. "Ben!... your freaking out."

He stared into her beauty green eyes, seeing the beauty in her full body, wearing his white shirt. "I'm not freaking out about you Gwen."

"Your so like lying because I think last night was amazing for once when we didn't have to fight aliens all the time, we needed this break." The young redhead girl said, and the door clicking quietly behind her and he turned to her enjoying the view of her butt move back and forth.

Once she leaves, his mind wandered around her. 'I want to suck her tits again?... ok maybe the dweeb is right, I need to stop freaking out so much and enjoy my time with my cousin,' he thought in the back of his mind, the feeling of Gwen had suck him off to making him feel good "Uhhh yeah..." He moaned at the thoughts aside, of Gwen mouth as he clean his room for ten minutes as he heard Gwen voice came up the stairs again and through his door.

"... Ben come down here for a minute!" Gwen told him and he got up walking down the stairs. When he got there, his froze seeing a naked Gwen standing by him and he saw her cute tits out.

"Um... G-Gwen why are you naked?" The hero stuttered, trying to gather his faculties and he licked his lips as he saw her little tits as rub his neck nervously.

She move to him and unzip his pants that fall around his ankles, her fingers around his penis and licked her lips. "To have fun doofus!" Gwen roll her green eyes and she closed her hand around her cousin soft member and gently stroked it in his boxers. "See, Ah your hard and stop worry so much, Grandpa Max won't found out about what we did."

Ben eyes went wide when he saw his cousin licked her lips and he tried to squirm out of her grasp when she stroked his growing member up and down. Holding back a moan, the hero squeezed her shoulders in reaction to the touch of her. "Ah no!" he gritted out again "Gwen- you know this isn't right, we're cousin

"I don't, no one will know Ben!" She was stroking his cock up and down, she moaned as they kiss for a minute than she lay down on all fours and raising her ass into the air. "Pleeeease Doofus… have fun with me again, you can turn into four arms... I wanted your big muscles or jets ray when you can go fast on me," she whimpered, swaying her hips, her face in the floor as she looked backwards to him. "I need my hero cousin." Ben saw a naked Gwen on all fours before him. Gwen ass was big for her aga. Her young sex was wet still with need, which was hot, he crawled behind her holding her butt, and running her back. "Oh god Ben! Please!" Gwen moaned out. Her hips bucked backwards.

'This is wrong, but feel good.' His eyes move to her sweaty naked skin, and her two breasts, moving as Gwen rose behind her and gripped her slim hips. Bracing himself against her and he pressed his watch turning it on as he transferred himself to four arms as a red cock went in her sex and move his hips forward.

"Oh God That's right Fourarms I'd like! Feels so good and big…" She purred out feeling Fourarms red big manhood in her and she moaned out into the afternoon day.

Ben gripped her slim hips and started to pull backwards just a bit, before pumping into her body again and began to rock against her, pressing forward into her tight sex, feeling good, as he thought about having Gwen all day. Holding her hips, Fourarms trust a slow move. He pressed down into her body, moaning out each time he trust into her where Gwen whimpered.

Gwen panted against the floor, working her hips back. She hold herself up onto her hands and knees, moaning loudly and starting to thrust back harder, wanting more and feeling two big arms Fourarms grip her shoulders, and his other arms hold her big as he was bending over her and thrusting harder into her tight pussy as she bucked backwards, her green eyes squeezed shut, listened to the slapping sounds of her body ramming into her cousin each time they made love. Panting and gritting her teeth from pleasure, "Ben… Ah mmmm!"

Slamming his hips hard into her. Ben groaned out and slung one arm beneath her moving body and gripped her tits when he panted into her ear, "Oh God Gwen."

The hand capturing her nipple, and his arm holding her body and she cried out as orgasm overtook her.
