You're going through a rough breakup, so mom suggests getting away for the holidays and going to stay with your aunt. When you get there, your aunt dotes on you, telling you how much she's missed you both and excitedly telling you she's got so much planned for your stay. But it's been a long day of travelling and you and mom are both exhausted, so you head to the spare bedroom to turn in for the night. It turns out your auntie only has a double bed in there, but mom assures you she doesn't mind sharing if you don't? She tells you to turn away as she gets dressed for bed and though you're apprehensive, you agree to share the bed, your mind and your eyes focusing elsewhere as you ogle mom's naked curves. During the night, you wake up to find mom's hand clutched tight around your cock. Horrified that your hard-on must've been pressed against her ass without you realising, you pretend not to have woken up. You lay as still as you can as she strokes you, but when she begins to play with herself too, you realise she's wide awake. When she catches your eye, she apologises profusely, claiming she must have been somnambulating, but you beg her not to stop. She's reluctant at first, telling you it's wrong, but you're both so turned on that neither of you want it to end. Mom makes herself cum and drains you right into her hand before licking it off and wishing you goodnight. The next day, you're up early and having tea with your auntie. She claims she heard noises last night but you deny anything happening. All of a sudden, she's coming on to you, teasing your boner and telling you to keep this secret. Surely this can't be happening? Your auntie's lips are wrapped around your cock, sucking you deep and telling you how much fun you're going to have while staying here... Later that day, you go looking for mom and your aunt as you haven't seen them for a while. You walk in on them chilling in bed together, having a sisterly chat and they decide to broach the subject of what's been going on between you all. Mom admits that you're old enough now to know that her and her sister have been getting intimate with each other for years. And the fact that they both made moves on you since you've been staying here is a sign that you're ready to join in on the fun, if you want to. They reassure you they know it's a bit of a shock, so why don't you just watch mom and auntie first, and join when you want to. You watch, your cock growing rock hard as they make out, suck on each other's nipples and lick each other's pussies. When mom sees how turned on you are, she crawls across the bed to kiss you, letting you taste your auntie, and inviting you in to fuck them both together.
