i.e. slow penetrations, slow dapping, gentle dicks, gentle hands reaxing the dapped girl, caressing her, rather long takes adding to the gentle mood.
Could be the dap to convince your better half to watch porn together, or just a dap for the more feable harted.
Ideal example coming to my mind is the first gonzo.com DAP of Ria Sunn.
She gets paired with Mike and Vinny, and especially Mike does all to treat her really gently. At the same time its not just a dap attempt but a full fledged 4-5min dap workout in two positions. Ria is quite enjoying it, though she doenst burst into heavy orgasms. Its just nice, vanilla porn for a more romantic mood.

Any other examples coming into mind?

Nice eye-contact and almost lovers talk between Mike and Ria.

Adds really to the intimate feeling.

Mike anchoring her ass slowly getting Ria to moan a bit more.
