It's your older daughter, Heather.
From Create Your Own Story
"Talk later, Julie," you exclam hurriedly, ending the call. You have to not do this at home. The guilt is clear on your face, and clearer in your pants. Even at your age, it takes nothing to get you going, and just the idea of dirty Skype play with Julie has you stirring mightily in your pants.
"Come in," you say, shakily. Heather walks in, cheery and oblivious. She's wearing a pink tank top that reveals her soft shoulders, loosely fitting. You can tell she's not wearing a bra underneath. If she were to bend over even a little, you're sure you could see the lovely pink nipples on her D cup breast...ugh. Wait. What is wrong with you? This is your daughter!
"What's wrong, dad?" She asks, innocently. "You look weird. Was I...interrupting anything?" She giggles.
Heather has been flirtatious with anything that moves for the last couple of years. You know she hasn't had a boyfriend, and that probably doesn't help her situation. "Heather," you say, in a stern voice, staring her down. Eyes drifting down to her chest. Is she leaning over? You can see the curvature of her beautiful, pert young breasts...god, so soft...what would they look like with a load of cum? You shake off the cobwebs. This is your sweet little 16-year-old girl. "Heather. Not appropriate."
"Oh, come on Daaaaddy," she pouts, swinging her hands as she runs up to you. *No, no...* you think. She can't jump into your lap now. You try to turn away from her. Her smell is so intoxicating...maybe it's that sweet lip balm she always uses. She spins your chair back to face her, and gigling, she hops into your lap.
"Ah!!" she gasps.
