Reference/ideology to the point in a relationship at which the individuals are comfortable enough with each other to wake up in bed fully naked, with no sheets to cover them, a full-lit sunrise occurring outside, with absolutely no care or insecurities present. It is at this point that one will suggest to the other that pancakes are in order. Breakfast -always featuring pancakes- in bed followed by "I'm content and full" sex then commences. Hence: Sexcakes. Only possible in the most content and pleasant of relationships.
Having woken up in bed, fully naked, with no sheets to cover them, a full-lit sunrise occurring outside, the content couple have a little bit of snuggle sex, decide to make pancakes, bring them back to bed, eat, and get back to some more happy sex. Sexcakes mornings are the best, they both agree.
