(LEMON/SMUT WARNING!)
We teleported onto his bed, him looming above me.
"He-" I was cut off by a warm sensation on my lips. I realized he was kissing me and I kissed back. He wrapped his arms around my waist as he kissed me harder. It was passionate but rough. He licked my bottom lip, begging for entrace. I opened my doors wide as out toungs danced and battled for dominance. He won and explored the wet cave that was my mouth. He wrapped his hands around my waist and deepened the make-out session. He left my mouth and was breathing heavily. I started to push on his jacket and he got the idea, throwing it across the room and I started to take off my shirt and bra. He turned back and started to kiss and sick on my jawline and neck, he found my sweet spot and I moaned. He started biting lightly and gently sucking on it, the he became more rough biting it harder and sucking on it harder. He eventually broke the skin with his fangs, making me moan loudly, feeling the blood trickle.
I started to pull his shirt off him and I massaged his ribs and kneeded them. He moaned and pinned me hands at my head. He was so much stronger than me. I was powerless to stop him from sucking and massaging my breasts. I moaned and he switched breasts, rubbing my left breast in a circle motion and feeling him swirl his blue toung all over my nipple. He was pulling my (what ever kind of pants/skirts, or something else, you wear) as well as my panties. He brought his face op to mine and said,
"Have you done this before?" I nodded no and he sighed. "This is going to hurt, but just a little bit, just remember that we can stop when ever you choose." He slid off his shorts and boxers. His member was bright blue and glowing. He slid into me slowly and the pain was so that a couple tears went sown my face. He looked at me with an 'OMG' expression. "I-i'm okay." The pain was so immense but faded out to pleasure. I kissed him and he got the signal.
He started at a slow pace, hitting all the right spots, feeling him grind against my walls. He grunted. "Your s-so tight-t." I moaned out in response, I couldn't even comprehend words, my head was spinning. He started to go faster, and started to hit more spots, I gripped the sheets and threw my head back while moaning out Sans's name. He started to go at an impossible speed, and he his a certain spot. "O-ohh~ Sans~ right th-there!" We were a grunting and moaning mess. ~5 smexy minutes later~ I felt a knot in my stomach and Sans started to get sloppy. "S-Sans! I-i'm com-mming!" I yelled softly. "M-me-" we came together, him being cut off.
