Jack sank back and let her work his meat, providing deep mouthed suction that practically pulled his balls up into her mouth as well. The pressure and heat that Darla created on Jack's prick made the troublesome fact that this was his shemale dad blowing him not seem so important. Darla smiled around his hot meat; never underestimate the power of the blowjob. In truth, Jack had thought about this moment all day at school, when Darla's snake-like tongue would massage his shaft again -- he just wanted to come in her mouth. He longed for the moment when she felt him spasm and she would slow her motion and concentrate on taking his cum. There's something special about a woman who will suck a cock and relish the moment the semen bursts in her mouth and eat it up without wasting a drop. Having a hot slut hungry for cum was a dream come true. Jack wondered if Tiffany would ever get there.
As much as Darla sensed that Jack wanted to follow the Pastor's path down her throat, she had her own desires. She had already had a big creamy snack today ad didn't want to waste this hard on, but Jack hadn't been drinking like two nights ago. And had made it clear he would be hesitant to fuck her. She needed to seduce him. Darla got up from her position on the floor and laid her shoulders over his torso and her body along the couch beside him. Jack's cock glistened thick with saliva as it flopped out of her mouth.
"What are you doing?" Jack asked, worried she wouldn't want to suck him anymore.
"Just making myself comfortable," she said, putting a pillow under her belly. As Darla lay on the pillow, she felt it raise her ass up, accentuating her big round cheeks, which spilled out from under her short dress. As Darla worked Jack's cock back into her mouth, he got hornier and couldn't resist the urge to put one hand on her mid back and the other on her head to 'guide' her. She took a break to reward him by acknowledging this fact. "I like that you remembered to use your hands to show me what you like."
Jack managed a grunt, he was in deep concentration. Desperately wanting to come, he pushed her head back down deeply on his cock -- he felt her throat tighten on him. At this point, Jack wasn't feeling guilty, hell, she said she liked it. Darla let him take over, pushing and pulling her head deeper onto his cock. Jack grunted animalistic ally a couple times, the base of his spine started to tingle.... he was going to shoot soon...
And that's when Darla stopped dead. She felt his orgasm approaching and firmly squeezed the base on his cock and pulled off, 'edging' him. She squeezed up his shaft and was rewarded with a pearlescent drop of pre-cum. She licked it off and spread it across her tongue savoring the taste.
"Mmmm...You're not in a rush are you, honey?"
Jack shook his head 'no', but his hand on her back crept down her lower back and rested on her ass. She wiggled her butt encouragingly and Jack took the bait, pushing her dress onto her hips and exposing that big juicy ass. He spread his palm and squeezed and his fingers sank into her sexy ass as he gripped it.
The red silk panties clung to Darla's cheeks so tightly; she was practically ripping out of them. Seeing her rump's shape so round and full, Jack realized the panties were too small. And they were familiar.
"I've seen these panties... They're Tiffany's?" Jack mumbled as he pushed his groin into her face. Darla pulled his spit covered cock out of her mouth a moment to respond.
"They were your mother's." Then she lapped at the head, spearing her tongue into the slit. "You're wearing Mom's panties?" Jack was stunned by the revelation, then he quickly remembered how hot he thought his mom was. Jessica was five feet seven with a curvy figure. As sexy as she was, Jack understood why she was frustrated that her husband didn't use that body as much as he should. Jack thought his mom's 38c breasts were perfect and she has a helluva nice ass, though it wasn't as big as Darla's. Mom also had great long legs -- what Dad had always said lured him in. Jessica's facial features were soft, framed by medium length brown hair. What he wouldn't to nuzzle his face in her hair and then move down to suckle her juicy round tits. This momentary daydream about mom had an immediate effect on Jack.
Darla was sure she felt Jack's grip on her head and butt tighten slightly. His cock felt a little harder in her mouth. Could it be he was fantasizing about his mother? At this point, Darla was on cocksucking autopilot -- her chin and lips were covered in slobber as she let her son do much of the work, humping his cock in and out of her face with feverish intensity.
Darla would occasionally get a taste of his precum leaking from his rock hard tool, and while it was tempting to coax a full load of her son's cum into her mouth, she wanted Jack's seed as deep as he could get it in the other end of her body.
Darla wiggled her ass against his hand to communicate this desire. Sensing what Darla wanted, Jack slipped his fingers into her crack, wanting to please her. She spread her legs a bit to give him better access to her sweet asspussy. His middle finger found her smooth creamy hole and gently nudged it through the panties, eliciting a full mouthed muffled moan from her.
Her cock was already hard and pressing into the couch cushions, but sometimes just a tickle on a horny slut's asshole was enough to make her cum... it wouldn't be long if he kept it up. And Darla wasn't ready to come yet. She was impressed that Jack was learning how to get what he wanted by pleasing his woman. The boy's education was coming along fine.
Jack's legs trembled as he approached the point of no return again when Darla froze her motion, squeezing the blood from his cock again, "Fuck! What's wrong? Why are you stopping?" Darla's eyes widened, maybe she'd been too selfish. Jack was pissed and he roughly grabbed her hair. Darla squeezed her legs and ass cheeks together around his finger, trying to will it inside her. "Jackie, I need more your than your finger." Darla moaned longingly, "My pussy is sooo hungry for your cock. I want you to fuck me, baby."
Then Jack did something that caught Darla completely off guard. First he pulled her panties down and pushed his middle finger right to her asshole, gently rubbing it as he worked the tip inside. "I will fuck your delicious ass as much as you want... under two conditions."
As shocked as Darla was, she moaned as her hole opened for his finger, coaxing it inside. Darla would willingly take any part of Jack's body into her ass, but she had to know what he could possibly want.
