It's never this easy; Heather walks in on you two
From Create Your Own Story
You hear a footstep. This could be bad.
Parting Jessie's legs to either side you lift your own legs off of the chair and bend your knees in one motion, forcing Jessie upwards. She squeaks in confusion as you tuck your heels under your butt and flatten her dress down over your dick. Jessie is now propped up in front of you, her back still against your thighs and her pussy sitting against your cock. Her body is inches away from you, her legs splayed out to either side. Neither of you are in a comfortable position as your older daughter Heather pops around the corner.
"Oh, hey dad!" she cheerfully exclaims.
You're taking long slow breaths trying to calm down. Your heart is ready to explode. Jessie is staring at you, a look of fear in her eyes. Your dick is still twitching against her sex. You barely compose yourself enough to respond.
"Hi."
Heather stands in front of you, facing the television. "Don't tell me you're actually watching My Little Pony..."
You look around, taking in the situation again.
"Not really... but Jess was watching it."
Heather nods before eying up the two of you suspiciously. Your hands are holding Jessie's dress down but you worry that she can see something. That she knows something. You and Jessie are both very tense.
Thankfully Jessie twists her head around, stretching her arms back toward her big sis. "Hey sissy! Wanna see my pony?"
Heather leans down to inspect the small screen.
"Daddy helped!"
Heather rolls her eyes. "I thought I was your favorite?" It seems like she's addressing this to you.
"You know I couldn't have a favorite, Heather. I love all of you. And you were just as adorable as Jessie when you were her age." Although not nearly as horny.
Heather pulls the chair out from in front of you and plops down into it before changing the channel.
Jessie turns into you and giggles naughtily into your chest. She seems to think this is hilarious. You sigh yet again. Your youngest daughter is literally sitting on your dick giggling while your oldest is nearly within arm's length and seemingly unaware of what is occurring next to her.
You try to think of a way out of this when Jessie twists her legs on the couch, planting her knees into the cushions. She leans back the few inches of space that she has and presses her back into your legs, allowing her to push her pussy against your cock with surprising force. Then she starts wiggling her hips up and down, sliding her lips up and down the underside of your shaft again. Her movements and short and shallow but effective. Your cock throbs. Her slit feels damp. You're not sure if it's your nervous sweaty dick or her young aroused sex, but there is definitely some sort of lubrication helping all of this along.
This fucking brat. After narrowly avoiding getting caught she wants to keep this going with her sister in the room? This is crazy. This is stupid. This is... amazing. Fuck does she feel good. Maybe Heather won't notice.
