A part of you is still panicking. This isn't right, none of it is! Sure it's fun that the roles are swapped. You have always been the more submissive one in the relationship, so having this surge of dominance is. . . well different. You are trying to think things over. What can you do to reverse this, or maybe pull back on the changes that are seemingly still happening. Tomorrow morning you are heading right back to the shop. There has to be something you can say to fix this mes-
"Ohhhh" you let out a deep moan that derails your train of thought.
Mark has graduated from taking in the scent of your pits, to teasing your nipples. On the walk over here you would have noticed this elevated sensitivity they now have. No, this is new. You finally open your eyes, having been leaning back eyes closed while in deep thought. They are sensitive, but also bigger. Perkier even.
Mark notices your arousal, your thick cock now at full mast, and removes his face from your hairy musky pit. He gives you a devilish grin before sucking on your fully erect nipple.
"Ohhhh fuck boy" Is all you can manage to get out. 'Boy'... you think...guess that is a name that has stuck for Mark. You had never had sensitive nipples previously, so you never understood the hype around nipple play. Now, however, it's like your eyes have been opened. That an Mark was an expert at teasing them. From the sucking, to the soft nibbling, he KNEW what he was doing.
You can feel your breathing getting heavier as your heart-rate speeds up. Something that surely is easier to do now with your current stature and bulk. Pre-cum stains your jockstrap, another interesting change. You've never worn one before but it is comfortable. Thinking back on it, seems you have only ever worn them in this new form.
"Looks like you are getting a little bit more sweaty" Mark says before licking a bead of sweat from underneath your moob. "Haven't had the chance to make the bed, ill go do that while you dry off a bit. Don't be too long now Daddy" he says to you, hand on your chest. You hand goes up to meet his, holding it while you stare into his eyes for a few seconds. Your meaty sausage fingers are laughably larger in comparison to his smaller hands. The size difference turns you on a little. "Sounds good babe, I'll be in shortly" You bellow, attempting to still catch your breath.
While Mark walks away, you give his ass a nice squeeze feeling saliva beginning to pool in your mouth. Mark gives out a surprised *Yelp*, before turning to you. "Pervy old man" he giggles through his smile.
Old man? You get up from the couch, albeit with a bit of trouble. You are still not accustomed to the large protruding gut you have that greatly limits your mobility. Walking into the bathroom you notice something odd, your body hair. at first glance it looked like you lost some, but then your stomach sinks as you realize it's still there, but some of it has lost its colour, leaving you with patches of white. Your beard too! It isn't entirely white but you are closer to salt and pepper than to your usual hair colour. Your face has changed too, becoming more leathery and wrinkled. Laugh-lines that are more prominent, a few specks here and there from age spots.
Freaking out a bit, you run back to your pants, currently laying in the living room floor and grab your wallet. You sift through the cards until you find your ID. . . 47. . .Your new ID says you are 47 years old. You get a bit angry at all of this. These are years of your life that are being taken away from you. You need to go back to the shop NOW. Who knows what else will change before you get the chance! Heading into the bedroom you dart right for the closet, but stop.
On the bed is Mark, wearing a jockstrap of his own and his ass in the air while on all fours. Almost like in a hypnotic state you walk over to the bed, salivating once more, and begin to tongue his tight hole. You blissfully enjoying eating out your much younger boyfriend, sticking your tongue into and around his hole. you remember he likes it when you rub your beard into him too, so you proceed to do so. He moans and you can see he starts to buckle a bit.
"Fuck Boy, your hole is needin' a real mans dick, don't it?" You exclaim, knowing he wants to be penetrated
"yes Daddy Bear" he responds, slightly higher in tone.
"I need you to say it boy" you sternly shoot back.
"My hole needs a real mans dick in it" He pants between breaths.
You slide the elastic of your Jockstrap down, and your monstrous cock springs back and hits you under your hanging gut. Grabbing the lube on the side table, you lather it onto your massive cock. The first time you have gotten to feel it in its fullness. Before you go to town on Mark, you notice his dick start to get softer. no, not softer, but smaller. from 8 . . . to 5 . . . all the way down to roughly 1.5 inches. Still fully erect, but miniscule. You grin and let out a chuckle as you grab both side of his hips inserting your superior manhood into his hungry ass.
