With a closeup of his crotch... and Jenna's face.

Nathan stared in awe and lust at the image Jenna had sent.

Seeing his lover, his first committed girlfriend, shoving her face into another man's bulge with hungry, horny eyes, knowing her small-dicked, masochistic boyfriend was watching. She was obviously loving every second of it... The sight filled him with an incomprehensible emotion, one he both despised with all his heart, and one he wanted to revel in, to allow his mind to be twisted by the strange new lust he felt.

Jenna was being held tight against Sammy's sweat-stained, tight pants, his member pitching a gigantic tent in the black fabric that stretched taught against her lovely face, now disheveled and covered in sweat and drool. He could tell that even if her cheek wasn't held down against her gym teacher's crotch, she would still be there, caressing the massive bulge, pressed tight in-between Sammy's legs.

Nathan **** a shaky laugh to try and calm himself, wondering if having such a large cock being bound in such a small place was uncomfortable. He certainly would never know the feeling, not with his four-incher, seeming almost minuscule in comparison to the monstrosity Jenna clung to.

And as much as he tried to look away, Nathan's rapid heartbeat, his rampant arousal, it **** him to stare in awe at his lover. Because when he said she clung to the massive cock, he meant she buried herself in it. Its girth was hung over her nose, covering her eyes partially and leaving most of her expression to be shown in her body language and her excited smirk.

She held the underside of his groin, cupping his full, heavy balls and massaging them with one hand. With the other, she toyed with the tip of his member, a small amount of pre-cum dripping through the fabric, heading towards her smug, grinning face.

The air around them almost looked foggy, as though their sweat, lust, and excitement manifested into clouds of steam. It surely smelled strongly of the two of them, overpowering every other scent and sense outside of each others aroused smell, and Nathan felt he could almost feel the heat and moisture himself.

Nathan could only think of his fantasies now, his girlfriend's face being fucked brutally by a huge cock. He imagined Sammy's heavy balls slamming against her face as her skilled throat filled with the yoga teacher's full length, deepthroating him to his base, over and over.

Just as he had before, Nathan reached down to grasp at his fully erect cock, trying to fit both of his hands over his member, and yet he failed to find a way both hands could satisfyingly touch his length. He had never thought of himself like this before, being so insignificant, being so small and pathetic. Even as Jenna had played with him, teased him, made him pleasure her in other ways, he never felt so small and unworthy of his gorgeous, dominatrix girlfriend.

But now, staring at another man's cock, knowing it would soon be ravaging that very same dominatrix and making her its slut, surely being more than double his own length, he felt a bitter-sweet arousal, his masochism both hurting what little pride he had in this scenario, and skyrocketing his lewd excitement through the roof.

As he neared this conclusion, his small cock neared it's own climax. He stared at the image on his phone, desiring the humiliation that would come of his lover coming home and finding out he had gone against her will, that he had been unable to control himself thinking about her making love to another man. He fought against every urge to keep going, to push himself over the edge, and he grasped his member's head, halting all other stimulus as he did.

It almost hurt, but it hurt in the way Nathan had grown addicted to, and as he let his body's excitement slow, his own skyrocketed. He realized Jenna had never given him a stopping point, and he knew she intended him to fail, to give in to her punishment... and he wanted to more than anything else.
