Tell her.

You decide that maybe she should know. "Umm, Doe?" you say. "You've kinda got a mark on your top."

Doe looks down and sighs. "Oh, shit. Do you have a tissue?"

You stand up and go and grab some kitchen roll. When you return to the table to hand them to Doe, she is already peeling off her top. You try to protect her decency by looking away, but she stops you. "It's OK, you can look, I show my breasts all the time when feeding Courtney."

Sheepishly you turn around. Doe peels off her bra and exposes her huge tits. The nipples are large and red, and the left one has white tears of milk coming from it. She grabs the left one and starts wiping it all around, dabbing the nipple as her hand passes. You never considered it before, but you realise that the sight of a lactating breast is strangely arousing, and your cock unavoidably starts to grow as you watch Doe play with her tit in this way. Doe looks up at you and sees you staring with fixed interest.

"You're enjoying this, aren't you?" she asks matter-of-factly. You nod, seeing little point in lying when your cock is now half erect. "Do you like my tits?" Again you nod. "Come here," she demands, smiling.

You stand next to where she is sitting. With her right hand on her breast, she reaches for your head with her left. "You know, the best way to stop the leak would be to pump out some of the milk." She guides your head downwards until you are **** to topple over or kneel in front of her. You kneel. "And since I haven't got a pump," she continues, "you'll have to do it for me!" Doe laughs as puts her hand behind your head and pulls you helplessly inwards. You can smell the sweet odour of breast milk before your mouth is engulfed by her tit. You suck greedily, and immediately your actions are rewarded by a gush of warm, sweet tasting milk. "That's it," coos Doe, "suck my tits dry!"

You oblige, your cock now throbbing in your boxers. Doe squeezes her tit and you feel the milk hit the back of your throat. You suck harder and harder, savouring every drop of her tit juice, until Doe stops you. She climbs off the chair and lays on the floor, beckoning you closer. You pull your boxers down and tear off your dressing gown, **** to spill your own white juice.

Her jeans are still on so you take the initiative and straddle her chest. Doe pushes her tits together and you drive your cock between them, eager for release. Both of her nipples are streaming white fluid as you fuck her tits on the hard floor. Your dick slides back and forth easily, lubricated by the flowing milk. Doe squeezes and pulls on her nipples hard, moaning loudly. You can feel your orgasm is close as you plough between her massive orbs, so you pull back and start wanking your cock until, with a grunt, you release across her tits, on her face and on the floor around her. You sag, your dick in your hand, and then stand up.

Doe lays there for a minute, coated in her own milk and your cum. Eventually she sits up, your thick jizz sliding down toward her smooth belly. "I think I need a shower," she says, grinning.
