Yes, against your will

You cannot help but star in disbelief in her breasts. They are not saggy nor are they too perky. They protrude outwards just enough that you feel like you could bury your face into them like pillows. Was this the result of breastfeeding for an extended period of time?

Joanne smiles, a little amused at your dumbfounded expression. "Do you like these, baby? You can thank your sister for making them so big. Every time, I breastfeed, it feels like it takes hours just to empty them out, so please let me know if you become too full. Okay?"

You lightly nod, though you are surprised to discover that Lisa has nursed from her mother, as well.

With that, she pulls your head up and wraps her arms around your back to position your head right in front of her breasts. Not seeing any reason not to suckle at these lovely melons, you take a deep breath and latch on, groaing as you snuggle and bury your face into her right breast.

Joanne flinches and lets out a soft moan. As you press yourself into her chest, she lovingly strokes your back and holds you tighter in place.

"It's much... different breastfeeding a boy, but not unpleasant," she says, "Just take it easy and slowly, okay, baby?"

You grunt in response, feeling your cock leak a lot of precum in your diaper as your lower half quivers. You suckle and even lick her nipple with your tongue, tasting a river of sweet milk as she holds you. Moans fill the room as she breathes steadily. All the while, you make slurping and suckling noises which a true baby would never make.

It does not appear she minds the suckling. Perhaps her daughter has done the same before. What a sight that would have to be.

You sometimes forget you need to unlatch to breathe in. But every time you get some air, you dive back in and suckle like never before.

Eventually, Joanne has to relax herself from holding you and changes positions. Lying down on the soft with her breasts leaking milk, she has you lay on top of her. This may seem crazy, but you are not about to stop.

"M-Mommy," you mutter without even realizing. Perhaps it was due to the maternal warmth she was emanating. It was quite nice.

Grabbing both of her breasts, you take the initiative and suckle on her left breast this time. You cannot help but lower your crotch against her thigh and rub against, jiggling her body as you hump.

Joanne can feel your hard diapered cock and is a little surprised, but apparently she expected as much given your excitement.
