We called out to some college couples who were on a double date at a hot spring, and secretly proposed a mission to the girlfriend of one couple and the boyfriend of the other! Have an affair while on the trip without telling your lover! The mission started with "holding hands" and gradually escalated! Finally, the affair took place next to the sleeping lover! Even if you try to keep your voice down, once you insert your dick... you can't hold it in anymore! Once you do it once, it's the same the second time! We monitored the two of them as they kept cumming inside for 2 nights and 3 days!
