For me, it's Scritching WD's ears as I recieve head that could be better, after I've tied her up naked, put some nipple clamps on her, and slid a large vibrator into her not as tight as you'd expect asshole.

Scritching WD's ears after putting her into very tight bondage, opening her shirt, adding a pair of nipple clamps to her, slipping a buttplug into her not as tight as you'd expect asshole, and then switching it to vibrate at full speed.
