You weren't trying to eavesdrop but hearing what she was talking about, you couldn't help yourself: she's so horny, post partum, but she's not getting any attention. Should you think about her like that? Of course not. But can you help it? Of course not. It wasnt like you planned to try and incite something, when you sat down to talk to her, after listening in. How much did you hear, she asks? Enough. Enough to know she needs an ear. Maybe some advice, from the male perspective? That she agrees tells you you've got a chance, to convince her its not wrong, that she deserves to feel good. Go ahead, you tell her, try on the new dress and lingerie you bought to get his attention. Do it for you, you tell her. Do it for me. She looks so good in that yellow floral sundress. God, shes pouring out of it. Her tits, so full of milk, pressing against the fabric...her hands grazing against her chest, drawing your eye to her hardening nipples...dripping milk, wetting the lacy fabric of her new bra she shyly shows you. You, the last person she should show herself to. Flirt with. Fool around with. But now its gone too far to stop. Her, teasing and squeezing her nipples, milking herself all over your hard cock, rubbing it against herself...
