MJ wants a little fun before lunch.

Finishing off the bag of hot dogs, Peter tossed the plastic bag into a nearby garbage bin as the two waited on a crossing light to change. Still pressed up against the man and leering down at his large frame, MJ exhaled and licked her lips. Leaning up to whisper into his ear, Peter's eyes shot wide when he turned and looked down at the woman who gave him a sultry look and darted her eyes towards an alleyway.

"Really? Right now?"

Shrugging her shoulders, MJ gave him a coy look as she turned and started making her way towards the alley, deliberately sashaying her hips with each step to draw his attention. It only took a look over her shoulder to have him chase after her and follow the curvaceous woman into the alley. The moment they were out of sight, Peter pulled her up to him and immediately kissed her. The two practically growling into each other's mouths as he pressed her against a brick wall. By sheer impulse, their clothes melted away until they were both nude, their hands exploring each other's expanded bodies. Peter groaned as his hands groped and hefted her larger breasts, finding they've grown an extra cup size in the span of hours while MJ hoisted her leg over his bare thigh, pressing her stomach against his and grind her hips against his own. Crawling up the wall, they continued to make out.

With her legs wrapped around his waist and her feet locked together at his back, MJ moaned and gave Peter a smoldering look, just as he managed to position his hardened erection at her moist folds and sunk all the way to the hilt into her. Leaning her head back and thrusting out her chest, MJ laughed as she felt Peter's lips clasp around one of her stiff nipples to lick and suck.

"Oooh TIGER... You've gotten so big..." She moaned between thrusts, finding his cock had grown longer and thicker, stretching her pussy with each thrust. Letting her hands roam over his sweat slick back, MJ gasped and moaned, feeling like she was being ravaged by a stranger, some great and terrible monster instead of her lean boyfriend. And she was loving every second of it.

"S-ss-so close, gonna... Gonna."

"Yes Petey, harder, HARDER, almost there... Almost..."

Then it hit them both, whether it was simultaneous or triggered by Venom as the creature kept watch on their stimulation, the two had an explosive orgasm at the same time. Their vision blurring as Peter flooded MJ's insides with hot cum and MJ drenched his waist in fluids that dripped to the alley floor 12 feet below. Gasping and panting, the two sweaty lovers eyed each other and made out again, moaning and swooning into each other's mouths before they separated and repositioned themselves, with Peter pressed against the brick wall and MJ pressing her ass against his gut. Still hard and throbbing, Peter thrust into MJ's pussy from behind, holding onto her arms to keep her aloft as she gasped and cried out in ecstacy.

Pounding into her from behind, Peter had a full view of her wide hips and meaty ass sway and wobble with each thrust. Drawing him to star at it hypnotically as he plowed into her from behind. Despite himself, he wanted to make that ass bigger, wider, heavier. He wanted to see her swaying breasts grow full and round, rivalling her head and sandwiching his cock. He wanted to see her grow more and more, and the images in his head only made him get harder.

"Fuck me Peter, fuck me HARDER, you're splitting me in half!"

The experience was otherworldly for Mary Jane, to be clinging to a wall like a spider and being fucked from behind. The vertigo was only making her heart pound in her chest just as fast as Peter was thrusting into her pussy. She wanted him to get bigger, to feel his cock grow so big it would be like shoving a bat into her. She couldn't get enough!

"Hnnnngk! Huaaaargh!"

The gurgle of lust was the only warning MJ got when Peter erupted into her again, triggering another orgasm in the woman as she shivered in his lap and felt him flood her insides again. Minutes passed as the couple panted and swooned, wiping their fingers through their sweat slick hair and crawl their way down to the ground to get to their feet.

"That... That was..."

"Amazing..."

Shivering from the experience, their clothes appeared again, leaving the two fully dressed as they checked each other over for any messes and finding none. Once they agreed they looked presentable, the couple left hand in hand out of the alley and made their way towards a restaurant, the tryst in the alley having done nothing to ease the growling demands of their stomach.
