Armin moves slow with him, starting with kissing. Letting Eren think he had any kind of power in this situation. Working Eren's clothes of him slowly and making baseless promises to get him to stay, Armin gets Eren completely naked.

When hands reach between Eren's legs he tries to stop Armin but his words die on his tongue at the shock of fingers pressing into his hole. It's not quite wet enough, the drying spit leaving a sharp burn with every movement Armin makes. It's obvious to Armin that Eren is in pain, the breathless little "Wait!" making him even harder. But Armin gets a little to rough and when he tries to add a third finger Eren pushes him away with more force, pulling back to the edge of the bed and hesitantly reaching to collect his clothes.

Armin stops him, wrapping his arms around Eren less to comfort him and more to maneuver him onto his front. Eren pushes back, but is stopped when Armin whispers more promises. He keeps them, raising Eren's ass into the air to run his tongue around Eren's hole, peaking in every once in a while to cause Eren such pleasure that he can't even think about his humiliating position.

When Armin slips his finger in that pleasure starts to meld into discomfort, the sting from penetration not any better than the first time. But Armin has a better hold on him now and he can't squeegee away as easily. He asks Armin to stop but before he can convince him to go back to something simple, Eren's pleasure comes back.

The fingers pressing deep into him blanking out his mind and killing any protest that may have passes his lips. Armin complements him for taking his fingers so well, for moaning so pretty from having his insides played like this. Eren cums as Armin presses in the fourth finger, screaming into the mattress and spurting all over his stomach.

As Eren pants, his ass still in the air, he feels a raw pressure on his hole. It's bigger than the fingers and it takes until Armin bottoms out for Eren to realize its his cock. For the first time since the affair started Eren gets a chance to protest, his words choppy and in time with Armin's thrusts.

It's pleasurable of course, Eren had heard of Armin's experience before even entering the bedroom but had not expected him to take it this far. So It's good, and Eren thinks he might cum again. Armin thinks he takes it beautifuly, telling Eren how pretty he looks filled up with cock, how nice his virgin ass feels, how he was made to take it face down in the mattress just like this.

Armin cum's inside him, not wearing a condom his semen spills out of Eren's loose hole as Armin pulls out. Armin only regrets that there isn't any blood
