Sorry that it took so long but here it is.

Deku's POV
I can't think straight. He has such a strong affect! Wait I'm too young to mate! I need to stop! I use all of my Might to climb off him and run to the door stumbling out. I run down a random hallway and fall to the ground. I can't walk any further. I feel tired and I'm exhausted. I start to drift off and fall asleep on the floor.

Time skip to the next morning

Still Deku's POV
I sit up and rub my eyes. I'm in Kacchan's bed again. What the hell happened? Everything came back to me. "Oh yeah..." i mumble under my breath. I slowly get up and walk to the bathroom door. I feel lightheaded and I have a headache. I walk into the bathroom and turn the shower on. I feel so gross I need a shower. I take off my clothes and jump in the shower.

Time skip to after shower

Deku's POV
I open the door to see Kacchan sitting on the bed. "Ah K-Kacchan!" I'm only in a towel and it's uncomfortable. He starts eyeing me biting his lip. His smell is so intoxicating. why does he effect me like this!? I need more! I walk over to him and get in his lap burying my nose into his scent glands. He smirks and buries his nose into my scent glands. It feels so dirty doing this. "I have a headache. That's why I'm doing this." I feel him smile against me and I continue. A knock on the door makes me jump off him and run into the bathroom. I forgot I'm only in a towel! I press my ear up against the door but all I hear are muffled words. I hear the person leave and I peek out to see Kacchan sitting on the bed with his hand in his hair. I slowly walk over to him. He's definitely angry, his scent is really strong when he's mad. "A-Are you ok?" I sit next to him and he scoots away from me. "Kacchan wh-what's wrong?" I scoot closer to him. He just scoffs and try's to get up. "No!" I grab his arm and pull him on the bed. I wrap my arms around his neck and pull him into a tight hug. He try's to push me away but I just squeeze tighter. "What are you doing shitty nerd!" I wrap my legs around his waist and keep him close to me. "I won't let go until you tell me what's wrong!" He struggles some more but I just keep on squeezing tighter around him. "Tell me!" He finally gives up and wraps his arms around me. "You asked for it Deku." He releases his scent making me loosen my grip. "N-No... fair." I let go of him and I start to pant. "You... couldn't h-have just used... y-your alpha v-voice." He smirks. "That's no fun now is it.~" I try to move away but he tightens his grip around me. "H-Hey... st-stop!" I start to sweat and my thing stands up. I pant even harder. "P-Please... it's t-too m-much.~" You know what! I can play the same game. I release my scent saying I'm in heat. "F-Fuck you... K-Kacchan." He makes a low growl. "That's n-not faire Deku." We continue the battle until he gives up and lets me go. "I w-won." "I only let you win because if we continued I would have mated with you weather you wanted me to or not. You could put me in rut with that scent fucker." I turn red and look down. Where did my towel go!?! I quickly jump up and look around the room. "Lookin for this?" I look over at him. He has te towel in his hand and he's smirking. "Give it back." I reach for it but he pushes me away. "No.~" "K-Kacchan please." I reach for it again but he pushes me away again. "Give it!" I snatch it from him and run into the bathroom. He can be annoying sometimes. I don't have any clean clothes. I walk over to the door and crack it open a little. "Kacchan! I don't have any clothes." "Yeah you do." Something thuds against the door and I jump back a little. I open the door all the way to see an outfit like my other one. "Thanks!" I smile and grab the clothes. When did he know my size or even get these clothes? I don't care, it's clean clothes. I put them on and walk out. "Thanks Kacchan!" I look around but he's not here. Where did he go?

Sorry it took so long. It's been a rough time. I'm going to start writing again note often now.
