Frisk POV

Well, I recently just learned that Chara is in heat? Huh, I didn't know Chara could go into heat? Wait, is it even possible for a human to go into heat? I don't know but this is definitely a thing that I can do for her so that we may get closer. Then again she seemed very adamant about me helping her through this but how would I do that?

Well, I should call them and let them know that I'm coming over. I pull out my phone and open my contacts and I see Asriel's number and my number? Wait, that just Chara's number. I know it looks almost identical but it's her number. I call it and hear the phone ring three times before I hear someone pick up.

"Howdy?" Asriel says when they pick up Chara's phone.

"Oh, hello Asriel! Hey, do you know where Chara is?" I ask politely.

"No, but I think mom does," Asriel says as he looks for Toriel his mother.

"Greetings, Frisk! What do you need to ask me?" Toriel says nicely.

"Hi Toriel, I was wondering where was Chara?" I ask them as dirty thoughts appear in my head about her. I shook them out and focus on the task at hand.

"Oh, Chara has been in their room and has locked the door. I tried opening anyway I could but somehow Chara made that door specifically magic proof. They aren't letting anyone enter their room due to their heat. I imagine she must be in a lot of pain not being able to do anything about it." Toriel says as she blasts the door once more and an explosion happens.

"Wow, they really made it magic proof! Mom, how did they do this?" Asriel yells in surprise.

"I don't know and they won't come out for anything. I know they have a mini fridge which is stocked up and a bathroom but this is unreasonable." Toriel says as sits down.

"I know right but she said 'that this time it's a lot worse' right before she locked herself in her room," Asriel says once again.

"Frisk please hurry and help Chara." Both Asriel and Toriel pleads with me.

"You don't need to beg me just think of it as a favor so you guys owe me one," I say after their pleading.

"Also, since I am going to be helping Chara, could you at least put her on the phone?" I ask wanting to hear her voice.

I heard some shuffling and some knocking as well. Then the exchange of a phone. I heard Haggard breathing.

"G-greetings? May I ask who am I speaking too?" I heard Chara ask but her voice is in so much lust that it could drown in it.

"Hello, Chara could it be that you are lusting after someone?" I say as flirt with her before visiting.

"Why do you patronize me with flirting?" They say as I hear a gasp and it sounds like she tensed up.

"Wait for me and I'll help you out okay?" I ask her already sure of the answer.

"Then please hurry, I don't know how long I can hold out,"Chara says as her breathing get rougher.

"I'm on my way so wait patiently alright," I say as I begin to run.

"Thank you, Mirror" I hear her say but the phone hung up on me before I can answer her.

After hearing that I increase my run to a sprint. I sprint passed everything and apparently leave some battles as well. I didn't notice it but I was told by Asriel after I helped out Chara so I believe him.

I see their house and sprint even faster and then I try to stop suddenly but since it was snow I slide quite far actually and then I fell on my but. I get up quickly and run back and slowed down when I came to their house. I knocked on the door and try to catch my breath. They open the door and smile towards me and let me and up the stairs and then they go back and let me handle it.

I smile to myself and knock on her door. I hear the door unlock and steps going away from the door. I smile to myself and slowly open the door to see a sight to behold. It was Chara. There was Chara who seemed very pleased that I arrived so quickly. They were standing there with her hood down! Now that I think about it I have never seen them take off their hood but there she was and her hair seems longer than usual. It seemed like the room was either full of Chara's love or Lust and then Chara look at me and they wanted to pounce but they wait until I came in fully before dashing to the door and locking and then flipping a switch to make it sound proof I think? Then Chara stares at me with eyes full of heat and lust. I think I see a hint of love in there as well but I don't know for sure.

To be honest I don't think I thought this through. She takes a step forward and licks her lips as she looks at me like I'm her next meal. I take a step back and then she moves forward and pushes me down onto the bed. Pinning me down onto it and then looking directly at me with her red eyes while her hair blocked everything else out. She smirked leaned in and kissed me! I know I should have been more excited that she kissed me but I just think is the heat and lust talking. Then let up and looked at me in confusion and then realized almost instantly what was wrong.

"You aren't excited about that kiss because it means nothing due to me being in heat, am I right?" She asks as if she knew!

"Well, if that is the only thing holding you back then you should know that I have had a bit crush on you and it's been eating away at me too to tell you. The only reason I held back is that I didn't know if I could trust you. You were a human and most times humans are dangerous and vile, but not you." Chara says she leaned in again but this time waiting for me to kiss her.

I was surprised, to say the least. I look up at her and I felt myself lean upward to kiss her. It was amazing I could feel her lust and love all in this one kiss. I could tell that Chara's heat didn't change her feeling but heighten them to unimaginable lengths. But it didn't stop there it only progressed.

I wanted more of her. I wanted everything she had to offer and she wanted it too. Yet she was hesitant to even do it, even though she is in heat? I had to admire her conviction but this is so intoxicating that I'm not sure I want to stop just at kissing and groping. I want more and yet I know I might ruin my friendship or any type of relationship with her if I do that.

Well, maybe I'll be able to coax her out of her shell. My hands begin to wander her body making sure not to miss a bit of it. Feeling her her sides and back and then going to the Chest and under her sweater~. I begin to massage her breasts. She tried to continue kissing me but she had no choice but to moan. She moaned loudly and her grip on my sweater tighten as we rolled over and I was on top.

I looked down at her and she was a bit of a sweaty mess with her hair everywhere. I smirk at the sight before Chara retaliated and began to grip my breasts massaging them to point where somehow my sweater was gone and she was just massaging them. She smirked at me and then took off my bra. I was surprised and startled at first but the pleasure she gave me was amazing. Due to her sucking on my breast. She resumed control and I was at her mercy and it was thrilling.

I loved it and it felt amazing but I felt as though she was left out. So what little strength I had due to her over whelming my senses I reach toward her lower region and my hand brushes against it. She yelps and jumps a bit before relaxing to my touch. She looks even more embarrassed. I look at her seductively as I wait for her permission and surprisingly she gives it almost willingly.

I slowly begin to reach down there to let her ease into it. Again to my surprise, she beckons me to do it. She looks at me as her eyes begin to glow crimson. I was enraptured by her eyes and I intended to give her what she needed. I was about to enter her with my fingers before Toriel and Asriel busted through the door and then they saw me without my sweater and possibly seen my hand down Chara's pants.

Well, I pulled my hand back and reached for my sweater and managed to get it on before Asriel saw but Toriel saw me putting it on. She got a suspicious look on her face before Chara manage to regain her sense of control and looked at them both.

"So are you going to explain yourselves or am I going to have to get angry?" She says with anger already in her voice.

Toriel seemed apprehensive and Asriel seemed scared. They both got up and were going to leave. Chara snaps her fingers and they both stopped dead in their tracks. Then they began to sweat profusely.

"So how should I punish both of you for one breaking my door ... again, and secondly not explaining yourself?" Chara says as they get off their bad obviously not happy at all with this outcome.
