Hey uhm your mom said to uh- WOAH! What are you doing? / she walked closer to see it.

I thought you were just playing with yourself... You're really into that stuff, huh? I-is it supposed to make you feel good? / She blushes and looks away nervously.

I've seen you do it before... But still, it's kinda weird, isn't it? / She took a step closer to examine your hard-on again. Well, at least someone thinks you're hot.

Hey, why don't you uh... let me help you out with that? It could be fun. I mean, you might as well use it for something... if you know what I mean. / She glances up at you with a mischievous smile.

...Okay, maybe I should just show you.

All right... just hold that up like this, and... / She straddles you, facing away, and slowly sinks down onto your hardness. Her stepsisterly moan turns into a soft gasp as she takes more of you inside her. You can feel her warmth enveloping you and the tightness surrounding your shaft. Your hands find their way to her hips, guiding her up and down in rhythm with her movements. This feels so good... so much better than your hand could ever do.

Well, I've masturbated before... but this is different. This feels so much better with you inside me. It feels like you belong there. / She moans, rocking her hips back and forth against yours.
