Eren X Mikasa fanfiction

Chapter 4: Threesome

Mikasa woke up next to Eren. She turned over and saw Armin staring at them. "Fuck!" Mikasa yelled. Eren immediately stood up and looked around only to see Armin, staring at them in confusion. "Armin... Listen..." Mikasa started to say. "Look we..." She couldn't find out what to say, she didn't want to lie, not did she want to tell the truth. "Yeah yeah, I know.." Armin implied, "you two had sex, congrats, now clean up all this semen off of my pull out mattress." And threw two towels at them each.
Eren was walking around with Mikasa all day. With that little shit eating grin on his face. Occasionally Mikasa would look at Eren and give him this look that said, "stop." So he did. Mikasa couldn't walk properly. She would have to kind of waddle at her hips and this was a pain, especially when she was climbing up the stairs to get to 4th period. "Mikasa, need some help?" Eren said taking her backpack off. "No, I got this." Mikasa said reaching for her backpack. "Please, let me help you for once!" Eren said hissing at her. They stared at each other and Mikasa finally gave Eren a pissed off glare. "Fine!" She said dropping all of her books. Eren picked them up and put them in her backpack. He then proceeded to pick her up bridal style and carry her up the stairs. "Eren... About last night..." Mikasa started to say quietly. "No, it's fine... I'm sorry, I'll never do it again." Eren said speeding up. "No, I loved it!" Mikasa spurted out. Eren stopped for a second and looked at Mikasa. "But... If I have to carry you up the damn stairs something isn't right..." Eren said whispering into her ear.
"Fuck... Uhh what?" Eren said staring at Mikasa with a mouthful of ramen noodles in his mouth. "A god damn threesome with Sasha?" Eren said with his eyes wide open spitting out his ramen noodles and then coughing. "Oh hell no!" Eren said. "It'll be fun!" Mikasa said sitting in Eren's lap. "Yeah, until there's a chance of two screaming little shits on my hand..." Eren said putting in another forkful of ramen noodles into his mouth. "Trust me Mikasa.. If I were to impregnate a woman, chances are it would be you..." Eren finished with. "Listen, yes or no?" Mikasa said squeezing his thigh. "Fuck! Ow! Jesus! No, no, no!" Eren said. "Ok." Mikasa said smiling, running her finger up his cock, "oh brother..." Eren said already on his way to the bedroom.
