You hear your mother from the bedroom--she sounds exasperated. When you peek in, you see her pressing on her full, milky tits. Ever since she got pregnant, her tits have been enormous--even more so now that she's full of milk and breastfeeding! You're jealous, and even seeing her trying to express it by hand has you rock hard. You clear your throat and she jumps a bit, covering herself a little before inviting you in. You can tell she's uncomfortable. She tells you that normally, when she needs to get rid of extra milk, your father helps her with it but he's away for work. "I just don't seem to respond to pumps," she says, pressing her gorgeous, full tits. "He, well...he uses his mouth, and that does the trick," she tells you, a little embarrassed. Why don't you help her, you ask? She balks, saying you're far too old to breastfeed, but you break her defenses down: its ok, you're still her boy after all, it'll be just like before, it won't be weird at all! Eventually, she acquiesces, and you position yourself beneath her, looking up at her perfect, engorged tits as she offers you a dripping nipple. Your cock practically bursts through your pants when you start to suck, hearing your mother moan as you provide her with her long sought after relief. You keep sucking, flicking your tongue and trying to resist the urge to whip out your dick and jerk it all over her tits...when you hear a new moan. A pleasure moan. You can tell she's starting to really, really like this...even if she shouldn't! You focus on her moans, making her breath speed up, her heart race, you can hear it in her voice...only a little longer and she won't be able to say no, a little more of your mouth on her tits, and she won't want to say no!
