I won't tell if you don't

After a long week of only going over syllabi in class you were exhausted. Mentally and physically. The only thing you could think of when you walked back in to your apartment was drinking a nice hot tea and watching a movie alone in your room. Instead you were met with a practically naked Eren, clad in only a towel that hung loosely around his waist.

He smirked as he saw your flushed face, "I'm going in the shower," he headed towards the bathroom before giving you one last look over, "if you care to join."

You weren't sure what the energy was between you two anymore, but by god did he make your knees weak. You quickly locked the apartment door behind you and scrambled to your room to undress. You didn't know what you were thinking, all you knew was your body was acting on instinct, as you quickly pulled on your robe and made your way to your shared bathroom.

Your heart was beating through your chest as you placed your hand on the unlocked doorknob. You wanted to sike yourself out. You wanted to turn around and pretend you never heard him. Last year you would have never agreed to this, but something changed in you and you knew deep down that if you never got him out of your system, you would regret it for a lifetime.

You opened up the door slowly, your eyes traced his silhouette through the shower curtain. You slipped your robe off and hung it behind the door before sneaking in to the shower in front of Eren.

He smiled back at you, suds still in his hair, "took you long enough."

Eren pulled you in for a long kiss as the shower head rained over you. You clung tight to his back afraid that your feet would slip right under you on the slick floor. He pulled for the kiss and looked at you with such fondness in his eyes, it made your stomach feel like it flipped.

"Sit," you commanded shyly, pointing him towards the indented seat on the shower wall.

He raised his brow at you, but obeyed nonetheless. This was the first time you were seeing him fully undressed, and his body did not disappoint you one bit. His abs glistened under the water droplets .You took a shaky deep breath as you placed your hands on his thighs before kneeling down on the cold shower floor. Once properly adjusted on your knees, you took his length in your hand stroking it gently.

You looked back up at him, your mouth millimetres away from touching the tip, "think of this as returning the favour."

His head leaned back as your tongue swirled around his tip. You teasingly brought him in and out of your mouth, feeling him twitch and tense at each new movement. Eren watched you take him in fully. As much as he loved seeing this new found dominating side to you he couldn't fully let you take control. His hand reached behind your head, tangling his fingers in your hair. He bobbed your head up and down his shaft. Moans escaped his lips as the pressure from inside him forced its way out in to your mouth. As Eren pulled your head back, you let his cock sit on your tongue wet from the saliva from your mouth, his cum and the consequential down pour of water from the shower head. Your eyes looked back at him doe eyed and teary.

"Pretty," he said as both of his hands cupped your face.

He brought you up on his lap, kissing you down your neck to your shoulder, leaving quick love bites in between.

Eren wrapped a towel around your naked body, hugging you tightly from behind. He left a sweet kiss on your shoulder where there now sat a bright red hickey.

"This is the last time," you turned your head up to face him.

He looked down at you with his teal eyes, his expression soft, "I won't tell if you don't."
