My brothers semen
When I was 18 I had dated but was still a virgin. I was curious and lusty. I asked my brother what was wrong and he said he'd need to see me naked. I blushed and said no way. A few days later I asked him to let me see his penis and I'd show him my boobs. He did and I did and he got really erect, stroked himself to orgasm. I had never seen such a mess. And it smelled like bleach.
