Both of them were planning on giving their boyfriends their first kiss but "someone" decided to beat them to it. Also Tsukihi mentioned that Karen and her boyfriend's relationship have been rocky ever since Nise 1. Their boyfriends also remind them of Koyomi and they did indeed started dating them in order to make him jealous. Tsukihi however also mentions that the reason she started dating was because her boyfriend told her that there is no point in calling the person you love onii-chan.

In conclusion, Karen and Tsukihi are in love with Koyomi but have boyfriends at the same time.

The Araragi children was definitely related seeing how all three of them are dating someone but in love with other people as well.

So like brother like sisters, you're suggesting that maybe Karen and Tsukihi are having their own secret reverse harem despite dating a boyfriend and also brocon?

Spoiler for 2nd response:

My guess would be, they both had a partner,just to shield out their real love interest. Karen and Tsukihi : brocon. Koyomi.... lolicon toward Mayoi
