This is a plausible scenario for the (not too distant) future after the hours long, nightly, orgy [and could even include Pete as the "manager" of the cottages on the island]
The Kelly and Dylan interaction in these pictures is just the depiction of a dream that Dylan was/is having similar to Au Naturel-3-5--Dylan-s-Dream-Bathroom.
The totally different body color of Dylan is the indication of the fact that it is a dream of Dylan in Au Naturel-3-5--Dylan-s-Dream-Bathroom.
In the "Yoga" pictures Dylan has the same/similar body color indicating it's "just", but an understandable another dream that Dylan has/had.
That is not to say that it could not happen. I can totally envision Kelly and Dylan taking a stroll on the island, the day (or several days) after the hours long, nightly, orgy, with Kelly using the excuse of having to practice her (neglected) yoga routine. Of course Dylan will end up being fucked by Kelly because there are still remnants of the aphrodisiac in her system and because of that she insists that Dylan blows his load deep inside of her.
[Looking at the "speed" of which PS is producing Chapters/pages I guess all of this will not happen before Chapter 31 though]
