Nipples hurt

Hey guys, so this may be a bit tmi. Last night I (female) and my partner (female) were.. planning to do some fun activities. I got extremely aroused, but unfortunately we have to end it early before anything really happened. My boobs were touched a bit (over clothing) but nothing major. We went to sleep. This morning I wake up and my nipples specifically hurt like a bitch. Was wearing a sports bra- that hurt a lot. Currently in a bit of a looser cupped bra. If anything touches them, brushes past, or I move weirdly and the cup brushes against them, they hurt. I’ve never had this happen before. My nipples weren’t touched last night, just my boobs. It’s not a normal period/ovulation symptom for me. I’m 12+ days away from my next period. They don’t seem/look abnormal- but they hurt like a bitch. My boobs in general feel fine, it’s just the nipples. Any ideas why??
