Hearing clanking noises from down in your home's garage, you slowly start to rouse from you sleep. 21 wasn't in bed with you, so, that meant she must've been working again... being the scientist she was, this was a given.
You and Android 21 have been together for about a year now. After all the mumbo jumbo of becoming evil, turning people into candy, her personalities splitting, and the soul-linking shit, Android 21 had surprisingly become your girlfriend in the end. Goku and Vegeta (along with the rest of the Z-Fighters) were pretty skeptical about her, but the more you pleaded for her to stay with you, and the more the Z-Fighters kept a close eye on her, they soon came to accept her and the two of you being together (especially after 21 surprisingly managed to become good friends with Bulma, both of them being geniuses when it came to technology). I mean, Krillin has an Android for a girlfriend (and now wife), so, why couldn't you? Even if 21 was absolutely crazy-evil before... But, the world was saved once again, and everything could go back to being peaceful. Right..? Right, totally.
Sleepily making your way downstairs and to your garage, opening the door to expectantly find the beautiful Majin-Android in her true form (as per usual nowadays), humming and working away at... well, whatever she was working on. Before you could even say anything, or even take another step, 21's long, pink tail tightly wrapped around your waist, and slightly lifted you up off the ground with ease, pulling you in closer to her before she delivered a firm kiss to your cheek.
"Morning, hun. Sleep well?" She asked, not even giving you a glance yet, still too engrossed in whatever she was doing. Though, she did keep you slightly off the ground in in her tail's grip, the tip lightly flicking over your stomach.
