SUMMARY
Only With Consent (Official Uncensored)

Sang-wook and So-eun, who were enjoying a sweet honeymoon, have a chance to meet with Joo-hee and Jong-hun couple during an excursion, and four people are attracted to each other’s partners. Among the pleasant drinks, the level of the game started is not unusual.

I recommend reading the manhwa on PC using Yomikiru, and on Android using Tachiyomi.
