You help clean up and then help Rebeccah another way

Rebeccah carefully scoops up the pool of cum on your stomach with the edge of her hand and tells you to open your mouth. Without thinking too much, you comply, and she tips her hand, dribbling the goo into your mouth. You feel humiliated as you swallow. It tastes salty and a little bitter and you can't help but feel a little grossed out by it.

"Come on now," she says, admonishing you gently. "Don't make that face. I know you've tasted it before. In fact you've eaten John's cum straight from mommy's pussy, haven't you? That's a good boy, swallow it all down for me."

Rebeccah wipes you down and lubes you properly, replaces your plug and starts to diaper you.

"I have to say," she says offhandedly. "I was a little surprised how quickly you squirted when she put her boob in your mouth. You seem to have developed a full fledged mommy fetish, haven't you?"

She finishes putting on your warm, soft diaper and cover, patting the front affectionately.

"I don't mind though," she says. "I think it's sweet how she takes care of you, and I can't really blame you for being a little obsessed with her breasts. Now let me find a shirt for you."

Rebeccah goes over to your dresser and opens a drawer.

"You were watching sissy porn too," she says over her shoulder. "Did playing dressup spark something in you?"

She pulls a shirt out of the drawer and holds it up. It's pink with a ruffle around the hem and sparkled letters spell out "Mommy's lil girl" on the front. She has you sit up and you blush as she pulls it over your head.

"Sooo cute!" she exclaims. "One more thing to make it perfect."

Rebeccah reaches under the changing table and retreives something that looks like big colorful beads on elastic.

"Let's see how pigtails look," she mutters, as she gathers the hair on the side of your head and then wraps the elastic around it, then repeats the process on the other side.

"Oh my god!" she exclaims even louder. "You are so adorable! I can't wait until mommy sees you! But we have to wait until she's done with her 'nap'. Until then, I have something I need you to do."

Rebeccah helps you off the changing table and leads you over to the bed where she has you lay on your back, while she wiggles out of her jeans.

"I didn't get to come last night. Sucking Brad's big cock really turned me on and I've been feeling frustrated and horny ever since."

She kneels on either side of your head and you can see her smootly shaven pussy inches above you. Spreading her legs causes her folds to open and you can see them glistening wetly as it lowers onto your mouth and nose. She starts to grind forward and backward, painting your face with her slick juices.

"Stick out your tongue," she says, her voice thick with excitement.

You hold your tongue rigidly out of your mouth, and she starts to ride it like it's a little cock. You are having a hard time breathing, but she seems focused on the pleasure she is getting from riding your face.

"Ohhh, yes. Just like that," she murmurs, grinding harder.

You try to hold your tongue out for her, even though it feels like it is starting to cramp. By now she is whimpering as she grinds down. You can feel her wetness running down your cheeks and she shifts so her clit is rubbing on the end of your tongue.

"Don't move. Just like that," she moans, moving her hips faster.

You are still having trouble breathing, and your tongue is aching, but she seems close, so you obediently hold out your tongue so she can get herself off. Finally as you are on the verge of blacking out, she starts to shudder and whimper, clamping her thighs on the sides of your head. When she finally pulls herself off, you gulp air in huge gasps.

"Oh sweet boy," she whispers in your ear, snuggling against you. "Did I smother you? That was soooo good!"
