imagine being a little puppygirl with the sweetest sheath and the softest balls wrapped in the silkiest fur and you get invited to your big sis' sleepover with all her big friends and they all coo over you and pass you around, one girl laying you across her lap with a paw scritching your tummy and another massaging your balls, another girl bouncing you in her lap while the others giggle at your wobbling sheath with the ruby red tip peeking out and dribbling on her knees, your big sis herself inviting them to spread you open and drink between your legs whenever they like, telling them how you always come crying to her for something warm to soothe your knot and laughing when you hide your heated face in her bosom, and they start dressing you up in their big girl clothes to see if anything is baggy enough to hide your eager pupbulge but you just stain everything with precum and have to watch them huff the darkened fabric while your ears are stroked and your tits are massaged and when it's all too much and you gasp around your sister's fingers as a creamy white rope bursts out from your sheath and paints a strip on the carpet, every womb in the room decides it's time to stake their claim
