As you lay on your bed for a few hours, rubbing your rubber fused underwear crotch in arousal, the black rubber slowly turns red and makes its advance on your skin you can't help but feel like rubbing a bit above the waist and bits below too and expanded your rubbing not only to your fused underwear. You keep on doing this and your hands soon turn red as the underwear and your fingers fusing like a love doll, but still aroused and oblivious to your change as the continue up your arms. Already, the red rubbber has changed your stomach and thighs and lower legs at the same time and then move your legs left to right at the same time and then the changes went to your feet as you moan in pleasure as the toes merge together leaving your feet look like rubber socks. It soon inflated a bit making it look like from socks to converse laceless shoe like feet. Same thing for your arms and hands as they became rubber mittens and completes the transformation on your arms and then meeting up with the source as it smooths away your torso making it featureless and rubbery. You then look down at your rubber body. You don't feel shocked, more like you wanted this to happen. "Yessss..... Please don't stop..." You hiss and moan in pleasure as it crawls up your neck and going around your head. It soon gets to your mouth and you feel it seal and smooth away and you let out a muffled moan as you then squirm your body rubbing your now rubber skin against the bed sheet as it soon covers your ears and nose as it is the same for his mouth. Finally, his hair was dissolved from the rubber as it engulfed his head, leaving his eyes. "Mmmmph....! <3)" You let out a muffled moan as your eyes close shut and seal up for good, but can see again but only can see red color. Soon it puffed up a bit making you completely featurless and gain a little transparency and continued to muffle moan as you move your whole body against the sheets until you passed out.
Later....
