We were grinding and she was really into it, and I suggested removing layers of clothing and she was very enthusiastic, then humping took place. Got a bit of precum on her butthole. Condom was suggested. Humping continued. Tip went in, asked if that was okay, she said yes, light humping continued for a few minutes and then we just stopped.
The precum bit was a lot of upsettiness, and apparently it going in was a problem, although at the time she gave all cues that she was enjoying it
She didn't really give me any indication that it might be a problem at the time.  She gave me lots of nonverbal indications of the opposite, in fact, hence my confusion
Also I broke up with Lillie as I left, due to her not seeming to care about my injury as well
that's when things went openly hostile over text
whereas before, things were fine although later in the night it was passive aggressively ignoring me
Shortly after I got hurt Lillie told me to leave, and I was sort of passing out on the couch
I remember hearing Hazel saying "If you wake up in the morning and there's a dead girl on your couch it's not my problem"
That bothered me
I'm not particularly invested in fixing this
I was sent out into the 17 degree cold with a concussion and had to wait for my bus for an hour.
