Who indeed...

Slowly it slid down, the head of the penis moving to graze against her starting back up after rubbing against her clit, sending an excited moan from her lips, dipping a few inches into her already wet pussy, wet from the thorough cleaning she had given it. The feeling of being taken in a place of safety was surprisingly enticing for MJ. So wired on rough, dominate sex the past few day she barely registered that she was being ****, or at least taken without complete consent.

Suddenly, the penis withdrew the lubricant from her pussy and the water dripping down her back must have made her ass slick, as the slim rod slid easily into her asshole. She puckered at the ****, not prepared at all, try as she might to clamp her ass shut, the damage was done, the man behind her was in. MJ felt the shower turn back on as a splash of freezing cold water made her more disoriented and with a final effort she used her one free arm and ass to try to push away from the anal intrusion. All she accomplished was to **** herself back so the full four plus inches was embedded inside her anal cavity. It wasn’t painful, but it was uncomfortable.

“Hahaha, do you like the friendly neighborly ass-fucking love?”

MJ heard her husband sneer at her. He actually sneered at her, she could hear it in his voice. She derived almost no pleasure from the violation, as she screamed at him to stop. She tried to twist around to look at him, how dare this small dicked piss-ant sneer at her, but before she could see through the water falling on her and her wet hair, she felt him grab her by the back of her head and firmly push her face first into the shower wall, while the other hand **** her to bend at the waist by twisting further on her wrist, causing her to yelp in pain. Once she was in position her husband used his supernatural strength and flexibility to hold her in place and set a blistering pace in fucking her ass. Her face ground against the ceramic tiles as she relaxed her ass to try and lessen the pain. This seemed to enrage Peter, as the pleasurable tightness suddenly loosened. She could tell as he released her head and sent a vicious slap to her beautiful bubble butt.

“Tell me you love being an ass-slut and I’ll stop the spanking.” If she could see his face, she would see his calm sneering smile; which would bother her but not as much as his milky white eyes which were looking at her with a hint of amusement.

“Fuck you Peter.”

“Fine. I can do that.”

Then as if she was in a dream she felt Peter released her wrist and sent a double spank down on both sides of her ass. All she could think through the pain was, 'that will leave a mark.' Then feeling him grip her hips she felt him pull out of her ass for a split second before shoving fully into her tight pussy. A cock which barely filled her ass, now somehow filled her almost as much as Craig had and Peter was something else when he straight fucked her. Hands on hips, holding her up, as he pummeled her body against the wall. He seemed to draw on all of his supernatural strength and speed to violently thrust his cock in and out of her.

Craig may have been slightly more filling, stretch her slightly more, but Peter knew her body better and when he released his grip he used the knowledge to his full advantage to play and fondle, twist and pull every spot he knew she enjoyed. Mary Jane’s brain was frozen between love and hate, anger and arousal, joy and pain. The freezing cold water cascading down didn't help at all. Peter seemed to instinctively know when and where she needed an extra touch, pull, or tickle. Finally, the lack of sleep coming with shock from the freezing water and the raw physical pleasure pushed her buttons to the stop, and with a low purr of contentment she came.

“Fuck, that’s good tiger.”

“Say my name bitch.”

“Peter.”

“That’s right, bitch, my name’s Peter, for now. Now say you love me.”

“I love you, Peter.”

“What do you love?”

“I love you, Peter.”

“You love me fucking you.”

“Yeeesssss, god yes. I’m cumminnnggg again Peter.” MJ’s howl rang through the bathroom and out the open window.

“Good girl. Now, back to breaking that ass.”

While MJ was still babbling, coming down from her orgasm Peter quickly withdrew and thrust back into her ass. Perhaps it was the suddenness, or the state of mind she was in previously thinking about Craig and her promise to him. Perhaps it was the orgasm he had given her, or that she was still numb from Peter’s hips hitting her ass, or perhaps something supernatural about her husband but she didn’t feel the second initial penetration. Either way, she wasn’t complaining as she thrust back to meet her husband reclaiming her anal passage. In her state, she felt a second orgasm fast approaching, though she felt as if his cock was back to its normal size.

"I LOVE YOU PETER!"

She came as she felt a gush of fluid enter her intestines. Her first anal orgasm in a long time. She turned her head slightly before she passed out from her second orgasm and falling to the floor, all she saw through wet hair and blurry eyes was Peter’s face, the bottom half she swore was covered in black. Peter’s cock slipped out as MJ fell and Peter merely turned off the water as he finished cumming on his passed out wife. Coating her back and ass.

Exiting the shower, he turned off the water and threw a towel on top of her before returning to bed. As he drifted to sleep, he didn’t notice a blob of black goo leave through the window with a toothy grin.
