⚠️SMUT/LEMONS⚠️

Sans POV

I slept with Chara!! And not like that ya sick perverts. Just for one night. I was embarrassed after getting rejected so I said nothing to her after like 3 days. I made a little bit of conversation with her, but not as much as I used to. I was still embarrassed. I want to make it up to her by getting her a gift, such as flowers or something. So I got her a bouquet of black roses because I knew she was kind of evil. Heh.
I knocked on her door.
"I uh- g-got these for you.." I said
I looked up at her and she looked different. Her eyes are usually jet black, but they were glowing red... Almost with lust.
I could feel my face heat up and my eyes start to glow blue but I squinted my eyesockets before it did.
Before I could say a word, she pulled me inside, slam the door and kissed me.
Mission accomplished.
Things got pretty heated though.
She had be pinned to the ground and started to grind me. No hiding my left eye glowing now.
She was wearing a skirt today, so I kinda felt her ass a little. Same goes for her breasts.
But, out of nowhere, she stopped.
I was worried.
She sat up and looked in a drawer in her room. She walked back out without a shirt, and a condom.
She smirked and held up the condom.
"Heh, we won't need this yet. Sex is like eating food. First, you blow, then you eat. But in this case, eating is fucking. And before you eat, put on the condom."
"Heh."
I took off my jacket and put it on the coffee table.
I fell into a deep, passionate kiss with Chara.
We slowly worked out pants off after about 15 minutes of nonstop making out, grinding, teasing, you know. Stuff that turns on anyone. Anyway, once her pants were off, I slipped my already wet, ectoplasmic member across her clit. Not totally in, because I didn't have the condom on yet. So I teased her for a minute or 2, Chara moaning in lustful pleasance. Then I sat Chara down on the couch, held back her hair, and she knew what to do. She started at the tip and blew me up and down. I tried to be gentle and hold back the need for me to start handing her violently. But I couldn't. I quickly shoved her up and down violently as a little choke left her mouth.
I did that for a bit, and I blew her off, and now it was time for the condom. I put it on, and I saw her adjusting herself and getting comfortable. No! She was not allowed to feel comfortable without my lusting presence! I shiver her to the ground doggy style, cuffed her, and fucked her, thrusting with all my pelvis had.
I slowed down, just then realizing how insane I had just been and heard Chara whimpering in pain. Her eyes were back to normal, but bleeding, she had bruises on her face... I felt awful. I looked down to see her bottom covered in my liquids and bruises. All because of me. I got both her and I into this... what came over me to do such a thing?!
"I-Chara... I don't know what came over me... you... you looked different... your eyes were red...  you even started the process but I finished it brutally..." I said with guilt.
"Sans- I don't remember anything you are telling me right now..!"
