You keep your promise

In an instant the thought echoes in your mind of what you had said last night 'If you had a penis and wanted me to suck on it, I'd do it. I love you, and I want you to be happy.'

'Oh Crap?', you think to yourself, 'what have I done?'

Subconsciously as these thoughts were racing through your head, your hand was playing with her new penis just like you do with your own normally.

"Mmmmmm," she moaned.

Thinking that you are not gay, but that this is your wife and you love her, you bring your head down to her crotch and suddenly are staring at her hard cock.

"Holy shit," you think as you see this monster. Her cock is long and thick and puts yours to shame, making you feel inadequate.

As you think these thoughts, warm wet lips engulf your cock and you moan with pleasure. Last night you were dying to get a blow job and now you're getting one and all you can think about is the cock staring in your face.

As your pleasure builds, you tentatively open your mouth, stick out your tongue and touch the tip of her penis. She can feel you there as she intensifies her sucking and as she hears you moan, she thrusts upward with her hips, catching you by surprise. Suddenly your mouth is filled with a warm thick cock. The pleasure you are receiving is intense and you can't help but suck on the cock in your mouth. It's so thick that it fills your mouth almost completely. You begin to slowly suck on the cock, but as your pleasure builds from her attention, she starts fucking your mouth in short rapid strokes. Her lips suddenly clamp down on your cock and you feel her mouth moaning on your cock. You can feel yourself just about to cum when her hips thrust up and you feel a warm liquid squirt from the head of the cock in your mouth. It shoots out, hitting the back of your throat, a second burst hits the roof of your mouth, a third finds you swallowing the first load to make room for more. As the fourth spurt fills your mouth, the realization hits you as to what you have just done and the combination of abhorrence and lust cause you explode in her mouth. A powerful orgasm hits you, better than any you've had in a long time. A fifth and final spurt from your wife's cock leaves her spent as you finish cumming in her mouth.

You both let out sighs of pleasure and soon fall fast asleep in each others embrace.
