Kevin forced himself to try to breathe evenly.
"Two more, baby," said Chrissy, loving how much this was torturing him. "Two more."
He kissed her deeply for a second, wanting to let her know how much he loved this. When he broke the kiss, she was smiling.
"So, you know what's coming next. He asks me if I really want to make Daddy feel good and all that, and of course at this point I'd do anything for him. And he told me to take off his underwear. He says he can't, he doesn't want to break The Rule, but if I really want it, I can take off his underwear and be his good girl forever. All I have to do is reach up and then I can have his cock for real.
"I thought this moment- when he asked me to break The Rule again- I'd be more conflicted. That I'd want to check in with you, or at least that I'd resist more. But if I'm being honest..." she bit her lip, carefully studying him as she spoke. "You weren't really on my mind."
Kevin squirmed with arousal at the thought of Mark's total takeover of his girlfriend. Chrissy was relieved Kevin seemed pleased she said that.
"Why not?" asked Kevin, barely able to get the words out. He knew the answer, of course, but he was begging to be teased more.
Her smile was wicked. "Oh, there were just... bigger things on my mind. So," she continued the story, "of course I reach up and pull them off, and this absolutely massive cock comes springing free. He's rock hard now, and of course it hits me in the face as I slip the band down. I have no idea if Mark did that on purpose, but I don't care. It's so heavy, so manly. I loved it, I loved feeling it slap against my cheek.
"I'm reaching into my underwear, I'm fingering myself, I'm losing control of myself to the massive cock... which of course I am kissing all up and down and licking and doing whatever to make him feel good. He enjoys this for a while, he's looking down at me, really enjoying the sight of his roommate's girlfriend on his cock. I can tell he really likes this because he's taking me from you- you know how competitive he is. He loves the sight of me finally giving into him. Then, he takes his balls- those huge, heavy fucking balls- and puts them on my lips so his whole heavy cock is sitting on my face..."
Her thumb moves again. There's the picture- finally the massive cock is revealed. It's huge, of course- several times his own size, noted Kevin. It completely covered the length of her face as he rested it on her. Kevin wondered, if he did the same, where his dick would reach. Her nose maybe?
"So I'm, like, determined. Determined to make him feel amazing. I'm gagging myself on this thing, I'm licking him all over. All the while he's talking dirty to me, calling me a good girl, making me call him Daddy. He's not being rough, but he is being firm with me, guiding me around. I'm fingering myself and I have my first orgasm right there, sucking him off."
"First...?" She came more than once with him? Just from sucking his dick?
"Mhmm. So I'm being such a slut, I'm doing whatever it takes. Slowly I try to take more and more of it in my mouth and then my throat. It's hard, but the more I do it, the better I get, and the more he praises me. But it's hard, of course. I've never had a cock half this big. He tells me if I really want him to feel good, I'll take off my bra. He wants to see my big titties, he tells me my big tits match his big cock. So of course, if it'll make Daddy happy- I reach behind my back and pop off my bra. I release them. He loves them, of course, he tells me how beautiful they are. I love showing them off to him, I love making him feel good with them.
"Finally, he pulls his dick out of my mouth, and starts jerking it above me. He looks so powerful, so hot. He asks me where he should cum. He says, 'You've been so good, baby girl, where do you want my cum? Tell me where?' So I tell him to shoot it all over my slutty face, and I stick out my tongue. I'm fingering myself again. Seeing him so close got me so fucking wet, looking at him jerk that big cock right in my face. It was insane.
"Then he says, 'Here it comes,' so I take my hands and lift up my tits to really give him a good view. It was hard to stop touching my pussy, because I was so close to cumming myself, but I wanted to be perfect for Daddy. So finally, he cums... and he cums hard. Rope after rope, totally covering me, plastering my face in hot cum. Nothing like your little squirts, he absolutely covered me. And it made me feel sooo good, it was sooo hot being Mark's little slut that I reached back down to my soaking pussy and rubbed myself and finger myself and of course I started cumming too, cumming under his big cock."
Her thumb slid again, revealing the final picture. There she was, as promised, her face absolutely covered with cum. Both her hands were down in her own panties, obviously pleasuring herself. Her big tits were pressed together by her arms. Kevin could see some of the cum had slid off her face and was dripping down her cleavage.
But what stood out to Kevin most of all was expression. The few times Kevin had given her a facial, she obliged, but was mostly annoyed with it. Completely drenched in Mark's cum, she appeared to be in complete bliss. She may even have been in mid orgasm for the picture.
She held the phone right in front of Kevin's face as her other hand jerked him off with much greater speed. "Look at your girlfriend being such a slut for Daddy. Look at how he covered me in his cum, covered your girlfriend in cum... he marked me, he made me his. Look at my face, baby, have you ever seen it like that? Cumming so hard? Cumming so hard just from sucking cock? Look at the cum on my big tits, Baby. Look at it on my face! Have you ever seen this much cum?"
"I'm cumming!"
"Cum for me, baby. Cum for your naughty girlfriend!"
And he did, shooting cum all over himself. He was extra humiliated that his roommate got to cum all over his girlfriend's face, and yet here he was, cumming onto his stomach.
He loved it. It was his biggest orgasm so far.
The both came down from those highs, and snuggled together, breathing hard.
"Wow," said Kevin, finally.
"'Wow' is right," said Chrissy. "Enjoy yourself?"
Kevin laughed. "I did. Jesus."
