Rob fucks Christy's mouth

You watch as Christy welcomes Rob's cock into her mouth, sliding her finger up her pussy to masturbate as she sucks it.

"Yeah, does this dick taste better than John's?"

You hear a muffled "mhmm" from Christy's stuffed mouth.

She envelops his cock with increasing arousal, fingering her cunt harder with every inch that gets in. You've never seen her like this, giving a blowjob with such passion. Perhaps for you she gave head as a gesture of her love; for Rob she gives head because she wants to savor his taste.

You see that Rob's enjoying this just as much as Christy, pushing her head down as she blows him and praising her oral skills. She takes his cock out her mouth and starts to lick it all around. Her tongue caresses his mighty shaft, going up and down over and over.

Then she made her way to his balls, letting them land in her mouth like falling snowflakes in the winter. She cherished his nutsack much more than she did yours, having barely ever touched it any time you two had sex.

"You have such large balls! Such a large shaft! Such a large head! Everything about your dick is so much larger than John's, Rob!" Christy said while tugging on his cock.

It never occurred to you that such a sight would turn you on so much, but it seems that all 3 of you enjoy the scene with equal pleasure.

As she sucks on his cock again, it seems like they're about to cum.
