"Stay still. You are now allowed to touch yourself, but must keep all your clothes on. You may cum, the aphrodisiac will stay in your system long after we're done here today." Levi's eyes sparked. He had never gone beyond orders. He was to teach endurance, but obedience? That was all on his own accord. And Eren's hot body was definitely worth the trouble this could cause him.
Eren didn't wait to be told twice. He grabbed his cock and began furiously masturbating. He had never found his nipples to be sensitive or arousing, but right now they needed to be fondled. He tugged at them, gasping at the sensation. Eren's glazed eyes saw Levi walk and in lean in front of his desk, looking at Eren. Wanting to comply, Eren spread his legs as far as his uniform would allow and stroked himself off in front of Levi.
Levi was enjoying himself. Sure, he wasn't the one Eren was stroking, but with time it would quickly come to that. Eren was very obediently spreading his legs, and the pre-cum staining his uniform was a sight to see. Levi's own cock felt the blood start coming in a rush. Eren was limp on the chair, his feet dangling over the hand rests and his hands trying to grip as much of his member as he could through the clothing. He used both his hands in a sort of lock, moving furiously. Eren's eyes held his.
"I'M CUMING." Eren shouted and his semen wetly landed on his underwear, making a wet spot on his uniform pants. No wonder Levi had sound proof walls. Eren slumped in his chair, suddenly exhausted, but still needing more. The aphrodisiac really did work throughout his system.
Eren's hazed eyes gazed up to Levi, his waist at eye level. He naturally reached for the bulge in his pants. Levi smacked his hands away.
"So much for obedience Eren. Have you forgotten that this is purely work? No pleasure should be found in our exercise." Levi spit. He knew that this was punishment enough for Eren, whose eyes sparkled with the tears from being denied his need for Levi.
Levi stepped back.
