Me and my girlfriend were just doing some foreplay I accidentally hit my penis in her viginal area. I don't know if it went in or just hit the outter side of it and I cumed. She screamed and then we went to the wash room and washed the vigina, there was nothing to be seen at her vigina but on her feet there was this blood clot. I freaked out. Then later there was no blood. What possible could it be.
