Both for Lazzy and I, too. Our most common position to allow for this is where he sits upright and I have the backs of my legs pressed against his tummy and chest. This places each of my bare feet on either side of his head, where he has quick easy access to them for tickling. And of course all my wiggling and squirming from the tickling just adds to his pleasure...not to mention what the sound of my shrieking, giggling, squealing, and begging does for his sexual arousal...lol
