The idea du jour seems to be mommy and daddy working together to give Lapine the spanking she deserves. One provides the lap, the other supplies the swats, and it's hard to be different in terms of lap. (In terms of swatting, they're both about the same force.)<br/><br/>The chief mostly uses his lap as elevation, mostly. When he's the seat, one knee is always being used to made sure that Lapine's is about ass high as the orc can manage. If he wasn't also actively using both his hands for support and stability; this would be a dangerous position for both parties.<br/><br/>Because he is, it merely means that Lapine's ass is about as close to window level as can be managed without standing on a chair.<br/><br/>Andy, by comparison, makes sure that each time Lapine is on her lap, it's a more erotic and active component than before. So Lapine goes from being spanked with clothed sumata, to Andy encouraging a little thigh-fucking during the spanking, to actively rubbing agaist Lapine's erection (well, as much as the position allows).
