Yes, but there's an exploit.

Karen stared resentfully at Sheri as the slut climbed out of the ambulance.
She knew the shameless whore was...a shameless whore, but calling her that to her face every time she saw the bitch didn't give her the right to fuck with Karen by making up some wild tale of a guy with a huge cock masturbating himself ****.

The bitch had even sent pictures, and they were clearly modified. Karen knew that some lucky women had a man who was big...down there... She had long ago realized that most men, especially the good ones, were at or below the claimed average dick size, as proven by that study circulated among her church group.

(Little did she know that her husband had slipped that into the group's conversation one day. Not that it was hard, since she didn't lock any of her devices or accounts. One might suspect that he had ulterior motives, which he absolutely did after reading a discussion of whether size mattered in his weekly checkup on Karen's activities. The controlling bastard. Though she doesn't know it, yet.).

As Sheri went to open the doors, Karen stalked towards her to unload just recompense for her tomfoolery. Proverbs 13:5 "The righteous hate what is false, but the wicked make themselves a stench and bring shame on themselves."

Sheri sighed inwardly as she heard the stomping approach of a Karen on the warpath. She heard the heavy intake of breath as the bitch prepared for her opening salvo of invective.

Best get it over with, she thought, as the ambulance doors swung open.

To reveal Penny 69'ing Maximus, groin humping his face as she deepthroated his massive cock.

Were his balls bigger?

She heard a sharp gasp from Karen behind her as the scene interrupted the woman's preparations, but Sheri had little attention to spare for such trivial matters.

She smoothly stepped aside, pulling the doors open fully and clearing the firing line.

Inside the ambulance, a little earlier:

Penny knew Karen was on duty, and that knowledge had somehow shaken her from her orgasm-induced haze. She'd regretfully stopped rubbing her nipples on Maximus's unreasonably ripped abs, instead removing the silly blanket that covered what should never be concealed.

His glorious manhood lay heavily on the massive orbs that fed it, recovering far faster than any other man could. His body was recovering as well, ever since the second bag of saline, as insane as that was. She didn't recall increasing the flow rate, but it'd clearly helped him.

She had to get him past Karen and fully recovered, if only to experience that cock at least once. She knew no other cock would satisfy her again after that, relegated to dildos alone forever, but it'd be worth it. She knew this somehow, without rational reason for it (apart from seeing the massive cock in front of her).

Just like she knew it was time to suck that cock.

Karen needed to see what she was missing, to be tantalized by the forbidden lust she kept locked inside her. Tantalized strongly enough to overcome years of indoctrination and repression.

And what better way than a demonstration of what a true cock was? Not that nub the asshole Karen had married called one. Unfaithful bastard hit on every women he saw, and had probably slept with more than a few, even after marrying Karen.

He'd tried with Penny, but the result was her now having photo and video evidence of his tiny dick, and thus leverage to keep him away from the women where she worked. Somehow Karen was convinced he was perfectly adequate, but Penny knew dicks, and that thing was just barely out of micro dick territory.

So Penny applied all her blowjob skills to Maximus's rod, marveling at it's majestic form, **** as she rarely did anymore, reveling in the feeling of a real cock at last.

She almost forgot her plan to get past Karen.

But when Sheri opened the back doors and stared at her for a split second of shock, Penny knew it was time. She knew Karen from years of working this area, and that bitch was sure to be on the metaphorical warpath after the report she had no doubt Sheri radioed in.

Sheri stepped out of the way, opening the doors wide.

"Schloooorp."

Penny reluctantly (and obscenely) removed the love of her life from her throat, the feeling of it's massive form sliding out triggering a small orgasm, and aimed it at Karen.

Obedient to her prior ministrations, Maximus's cock blasted a pint of cum directly into Karen's face. Most of it landed in her gaping mouth, of course.

More salvos were on the way, but Penny wanted them for herself, and with a loud slurping noise her lips were back on the beast before they came. She noticed Sheri glance at her jealously before turning to "help" Karen, but Sheri knew there was no need for such feelings. Maximus would have plenty to go around, she was sure.

But now was her time to feast.
