Yaoi double penetration

I remembered a story that I had read last year. There are a couple with the seme has curly hair and the uke has black hair.

I don't remember this guy is the seme's friend of what but then seme forces his uke to let the guy fuck him. But the uke really don't like that guy.

When the seme want to do double penetration on the uke, the uke has slapped the seme because he does not want

The seme getting sick after that. Hmmm
