your granddad calling you over to sit in his lap when you're still a teenager. you feel weird about it, you barely know the man. he had kicked your mom out when she got pregnant with you as a teen and it was only recently he'd reached out to you, inviting you and your mom to a family get together for the first time in your life. you were surprised when he answered the door. you never grew up with grandparents, but in your mind he should have looked so much older. it even crossed your mind for a brief moment that he was handsome, even though he was going grey at the temples.
you obey, walking over and sitting on his lap, even though you get a funny feeling in your tummy when he wraps his hands around your waist. it's long after dinner and you can smell the alcohol on his breath as you listen to the faint voices of the rest of your family on the other side of his large house. you hadn't realized just how well off your mom's family was, it was always just the two of you trying to make ends meet. his expensive clothing and home and furniture start to make you a bit nervous, your heart raises thinking about just how much power your own granddad has. the idea that it could all be shared with you.
"you've grown into such a beautiful girl," he whispers in your ear, "you look so much more... mature than your mother did when she was your age." you can't help but giggle, his deep voice causing you to blush.
"it's been so long since i had a pretty young thing in my lap," his hands trail down your bare thighs, teasing along the hem of your little summer dress. "an old man like me isn't turning heads like i did back when i was young."
"but you're still so handsome!" you exclaim naively. "i don't think you're old!"
he laughs, his nose brushing against your ear as he breathes you in. "be a good girl for me, sweetheart. do that for me and i'll take care of you. you'll do that for me, won't you?" your eyes widen, but you nod, pressing your lips together as his hand moves up to squeeze your waist, his other trailing up to cup your breast.
you press your thighs together as he slips your dress down, exposing your breasts. his big, rough hands grope your breasts, tease and flick over your nipples. you throw your head back against his shoulder as the old man introduces you to new pleasures. he praises you, telling you how good you're being for him. how safe you are in his hands, that if you stay just like this, he'll give you whatever you'd like.
he grabs you by one hip and encourages you to grind down on his lap. you're blushing all over feeling how big your own grandad feels against your ass. he pulls your panties to the side, circling his fingers around your clit until you're whining for him. he teases one finger inside you, alternating between teasing your clit and fingering your hole. you blush as he praises how tight you are, that he knew you were still just a sweet, innocent little thing. that you're so good for saving yourself. grandad holding your mouth closed as you cum hard around his finger.
he spins you around so you're straddling his lap and kisses you as you come down from your orgasm. he gives you a moment to catch your breath before he's zipping his pants, taking his big cock out. you look at him in panic, telling him you've never done this before, that you think he's too big. he just laughs, shushing you and takes your hands, telling you to just touch him. that he'll teach you what to do. brushing your fingers along his cock, squeezing the head, licking your palm and pumping it. grandad muttering curses between telling you how good you're doing as he turns his attention back to groping your breasts.
eventually gaining confidence, pumping his cock with both your spit slick hands, bouncing on his thigh while sits back and watches you. while he tells you all about how he's going to change your life. how you're his girl now. grandad grabbing the back of your neck and kissing you hard as he cums all over your fingers.
