I'll start from the beginning I guess. We met at school when a teacher paired us up for a lab, and we kind of hit it off. After a few days I gathered up enough courage to ask her out, and she says yes. We go get some coffee, just talk about random things, and she gives me her number. We went out a few times, then once after a movie I suggest that she comes back to my place. She agrees. We go up to my room and start making out. She slides her hands down to my belt and undoes it, and I pretty much realize that we'll go all the way. After fooling around a bit more, she gets on top of me and starts rocking back and forth. It gets to the point where she is about to climax. "I think I'm going to come..." she moans, and right as it happens I take a spear I had under the pillow and ram it through her heart. She coughs up a bit of blood, then tries to scream but I cup my hand over her mouth. "Shhhh," I say, "it's ok, don't be scared." I hold her until she stops moving. Anyway that was last week, I kind of just wrote it off as a weird incident, but I don't know what to think about it. I probably won't do anything like that again, I think I just wanted to know what it felt like, lol.
