You and your mother have decided to get away for the weekend, to the cabin by the lake your family has owned for years. You haven't been up there for a while. Of course, the weekend you choose is the weekend where an enormous storm rolls into the region. You get to the cabin safely, ahead of the snow, but the heat doesn't seem to be working. You can't get the place warm, and you're not prepared in terms of bedding and clothing. Huddled up on the couch for warmth, you try to get some rest. There's no use trying to go to bed in the bedrooms, there's frost on the inside of the windows and you can see your breath in there! You and your mother try to snuggle but within the hour, you're wide awake again, colder than before. You suggest trying that thing you've seen in the movies, where people get naked to huddle together and use one another's body heat. Of course, it's a little strange, it being your mom and all, but you two are desperate! You both disrobe and you try not to look down at her naked body as you press against one another. You try to go back to bed but it's no use, because now you're hungry and...well, you've got a growing erection. You can't be blamed for this! Your mother, she is gorgeous, her body still tight after having you and your sister, young. You try to resist the desire but you find your cock poking against her warm skin, and rubbing against her nakedness is unavoidable. Of course, she rouses, noticing the poking sensation of your rigid dick against her. You're poking her right at crotch-level, not wanting to want it but knowing that you'd give anything to slide inside her warm honeypot and just fuck her until you're both warm, hot, sweaty... Her resistance is perfunctory. She needs to tell you to stop, that if you move anymore you'll be doing something very bad - she needs to pretend this isn't what she wants. You understand that. "It's just to stay warm," your mother says, "it's just to try and survive," she reasons, reaching down to press you against her hole, spreading herself gently as you push forward, sliding into your mother's warm pussy and beginning to pump your straining cock into her. She pulls you on top of her and you look down at your gorgeous, shivering mother's naked body before pressing the full length of your cock into her. You watch her breasts bounce and jiggle as you fuck her hard, watching her face contort as she wrestles with the pleasure of you, inside her, and the knowledge that this is impossibly immoral. She shouldn't love it - neither should you - but both of you are lost to the giving in, the rocking back and forth of your carnal bodies. She pulls you down and you roll over, pulling her on top. She tries to keep the blanket over her naked form, the cold air pressing against the eminating heat of your bodies, but it slips, giving you a gorgeous full view of your mother's bouncing tits as she rides you, swirling her hips until she brings herself to orgasm with your cock gripped within her, the fluttering of her pussy sending you over the edge as you jism deep within your mother's hot hole. "It's just to stay warm, it's just to stay alive..."
