You try to do it as you are with some ingenuity and improvisation.

You both hauled yourselves up and with a great deal of effort and pushing fat around managed to meld yourselves together to kiss. You passionately made out as you huffed and panted at each other. Your hot breath and sweaty bodies created an intoxicating musk that got the two of you horny. You both worked together to undress and throw your clothing aside. You were the first to be nude and your gigantic belly and ass were free for Harry to see.

"My god," He gasps excitedly. "I never imagined being with someone younger, and bigger than me. But I can't tell you how you make me feel." You look at your blushing professor's exposed hairy chest and belly and push your naked body against him making him blush even more. His grin grows wider as he grabs at your belly before you move around him to grab at his pants that are still on.

"Why don't you show me how you feel?" You say as you begin to pull his pants and underwear down. "Show me how hard I make you." His tight pants finally pop off and fall to the ground after getting over the hump of his giant ass. With your professor's hairy cheeks finally free you grab an entire hug full of ass and squeeze it and rub your face into it and shake it.

"Please, I want you to fuck me!" Harry pleads. You let his ass go and very carefully get up and off of your belly. Harry stands ready and waiting as you line yourself up with his ass. You stomp forward and soon enough you encounter your first problem. You try and try and move and angle but your belly is just too big. It can't get over the hump of Harry's ass and just pushes against it.

"I- I don't think- This is gonna work," You pant as you wipe the sweat from your brow. Harry stomps around to look at you.

"Let me try with you," He asks. You nod and stomp to turn around. You wait as you still pant and heave to catch your breath before you feel Harry's giant belly pushing against your ass. Unfortunately, it's the same for him but his belly is too small to get over your gigantic ass.

"I didn't think so," Harry heaves as he gasps for air. "I had really hoped we could." You stomp around and look at your sweaty professor.

"We would need a crane for our bellies," you tell him. "They're just too big." Harry's face contorts and you can tell he thought of something.

"Wait! I do have a crane!" He says excitedly. "Follow me! In my bathroom!" He shocks you with how fast he turns and begins to stomp toward the back of the warehouse apartment. "It was installed to help me clean my underside, I think it should be sturdy enough to handle sex!"

You waddle into a large open bathroom and a shower area that looks more like a communal gym shower or something. There are dozens of showerheads around and above the space. But what takes up the most space is in fact a strap and a crane.

"Get your belly through the strap," Harry eagerly asks. You stomp forward and feel the leather strap go under your belly and wrap around it. You get about halfway before Harry stops you. He happily watches as you watch him press a button. A loud gear grinds to life as you begin to feel pressure below your belly and constrict around it. It starts to creak loudly as your belly is lifted. One foot, two feet, three feet. It starts to lift higher than your waist to four feet but it begins to strain and you struggle to hold yourself up as it lifts too high. But it thankfully stops.

"This should work!" Harry shouts as you feel him stomp around the room. You can't even see anything anymore but your massive fat body in front of you. Eventually, you feel his ass touch the underside of your belly as it just perfectly fits under it and he backs up into you. It pushes against your thighs and you both excitedly thrust.

It was sex, if you can call it that. Your fat slapped and struck but even as you orgasmed, it wasn't because you had penetrated Harry. No, unfortunately, your dick just hadn't grown with you and it couldn't overcome how much fat was on you and Harry.

"Well, I don't know what's sexier," You huff as you feel Harry pull away. "That we're so fat that we can't have sex, or that we're so fat and we wouldn't have it any other way." You laugh knowing you loved how fat you were. There was suddenly a thunderous crash as if Harry had fallen.

"Professor?" You call to no response, but you hear some shuffling, thumping, and gasping. "Sir? Are you okay? Oh, Oh god!" You feel Harry's hands on your thighs before his head digs into your fupa and takes your cock in his mouth. He ravages your genitals with his mouth and tongue as you squirm and shake as you stand. You cum easily and he licks it up before continuing to play with your genitals.

After some time you feel him let your cock go and thump away. There's a lot of huffing and groaning as he gets to his feet and lets your belly down. He's standing there with a giddy smile on his face. Your belly slams down and you get out of the strap to push into him and kiss him licking off your cum that is still on his chins.

"I want to suck your dick now," you tell him.

"Let me get into position," he says as you separate. He gets his belly in the strap and you haul it up. With some concern and a hail mary, you throw yourself down onto your belly and manage to get under Harry's belly. You grab his thighs and pull yourself into his hair and musky fupa. You dig in and find his precious jewels. You take his chubbed dick into your mouth and give him the best blowjob he's ever had as you can guess by the groaning, shaking, and pleading for more from him. You manage to make him cum multiple times before your jaw hurts.

You get on your feet and help him get his belly down. He charges you as well and makes out with you. Harry shows you how the showers work and you two get cleaned up of all the sweat and grime.

Naked and clean you both stomp back out to his living room and he urges you to sit as he prepares a quick feast for the two of you. He comes out with a banquet of leftovers, and chips, and cookies. You both eat and flirt all night before falling asleep in a food coma.

Harry has a small panic in the morning having had a student sleep over but it quickly fades as you make out with him. You help each other get dressed and he gets you a ride to campus for school. You go your separate ways as he has professor things to do and you have another class. As you stomp your way there to the stares and shocked faces of your fellow campus students, and as nice as last night was, you can't help but feel a bit upset that the sex didn't turn out how you wanted it to. But ideas were brewing in your head on how to fix that.
