Her tongue slithered down her girlfriend's throath, giving both of the incredible pleasure. It kept growing and growing until it eventually popped out of her ass, causing both of them to climax. Then her tongue continued to grow and went up her own ass, causing even more pleasure. Both of them can't wait for the climax when it pops out of her mouth again and finds her girlfriend's throat again and again and again
This loop - literally - was simply stretching them out further and further as it seemed that the tongue growth was stimulated by pleasure and by constant orgasms, which was something they were both feeling currently, as even if she tried to remove her tongue from her girlfriend's mouth, to try to stop the intense makeout session, it'd take literal minutes to do so, due to the sheer length her tongue had already achieved.
Her tongue looping multiple times in and out also meant there was an added thickness and not just length, since it'd penetrate over and over again, adding 'layers' to the point she could basically taste her own tongue too, adding to even more stimulation, more orgasms, and a never ending tongue that was bulging both of their bodies now in its shape(s), as it coiled before growing another several feet...
(This one feels like dejavu for some reason. Enjoy the hyper tongue fun!)
