Hot Summer Job/Tell Larissa to go deeper
Larissa is such a precious little thing. She's standing here naked and innocent with the tip of your cock in her mouth while she happily flicks her tongue to and fro. It's almost a shame that the only thing you want to do right now is fuck her face.
Straining against your cuffs, you buck your hips a little. Trying to force your way into Rissa's mouth, you're thwarted by the firm grip she has on you. In fact she doesn't even glance up from her task, despite the sharp jerk that pushes her head back. Your quick thrust does manage to push the rest of your glans out of your foreskin however. Larissa's lips are now sealed behind the ridge of your head. That only drives you crazier.
"Larissa..."
She immediately stops everything and pulls away from you.
"What?" she asks, almost worried to hear you speak, as if you're supposed to be an inanimate fuck toy.
"Can you go deeper?"
"Deeper?" she parrots.
"Yeah. Like, suck further down."
"Oh. Okay."
Larissa envelopes your tip again but this time she draws in even more of you, taking in a full inch of your shaft along with your head. She holds there a few seconds then pulls back, looking up for your approval.
"Like that?" she sings up to you.
"Yeah. But even deeper."
Nodding to herself she purses her lips prepping for another try. The exhilaration of having Larissa's thin little lips slide their way over the tip of your cock and down your painfully hard shaft is nearly mind shattering. She butts up against her hand, putting nearly half of your cock inside her mouth and resting atop her tongue as she pushes her limits a little further.
"Deeper," you repeat coldly just as she begins to slide back again.
Unsure but willing, Rissa releases her grip of your shaft and descends further down your length. She still only makes it about halfway before she stops.
"Keep going."
Confused about how to take any more of you, Rissa bobs her head about, sticks her tongue out past her lip, cranes her neck, all in an effort to discover how she can give you what you're asking. But her sister has a better idea.
"Just take it!"
Kylie suddenly presses on the back of her little sister's head sending your cock into the back of Rissa's throat. The small girl begins to choke and gag with your erection impaling her tonsils. Kylie leans in and holds her sister in place, apparently frustrated by her sibling's lack of success up until now. The younger sister pushes against your thighs in desperation which could have toppled you given that your hands are stuck behind your back, but luckily you are able to brace your calves against the coffee table behind you to counter her pushing.
You envision blowing your wad like this, shooting straight into this precocious little girl's throat as it frantically squeezes your meaty head. Of course you're no where near close enough. Kylie lets go in short order, releasing Larissa and freeing your angry member.
"That's COUGH-COUGH ...mean," croaks out Larissa.
"Not my fault you can't follow instructions," Kylie petulantly replies. "He said deeper. That's not hard. I just helped you."
"I didn't... need help!" stomps Larissa, swallowing hard.
