Drunk Stepdaughter Part. 4

Jack reminiscences about the last time using the serum.

Jack's life felt almost complete. Since he had discovered the pleasures of Lilly's unconscious body, everything seemed right with the world. He hadn't used the serum much due to fear of unknown side effects; however, he had used it twice more since the first time.
The last time he used it was the best by far. It was around four weeks after the first test, and he was almost addicted to the thought of doing it. He knew he needed to stop and agreed that he would do it one last time before giving himself—and Lilly's pussy—a well-needed break. It still marvelled him that she didn't seem to notice whenever she woke up, but he wasn't complaining.
The setup was the same as the other times. He waited for Kate to have a night away planned and then spent the day torturing himself with the images and videos he'd taken on the previous occasions. Then, when it was coming up to the usual time, Jack would make Lily her favourite cup of tea and wait another hour.
This time, however, it seemed that things might not go to plan. She had her cup of tea just fine, but she decided to stay downstairs and watch some trashy teen reality TV in the living room rather than go upstairs like usual. Jack decided this was a good opportunity to go to bed so as not to be around as she fell asleep, not wanting to raise any suspicions.
He went up and busied himself with pretending to prep for bed. After an hour of tossing and turning, he went downstairs to "get a glass of water," knowing full well that she would be conked out and asleep but still feeling the need for a potential excuse. He poked his head around the living room door and found Lily slumped, asleep on the sofa. Jack walked in and nudged her, calling her name. Nothing. He looked down at her. She was so beautiful with smooth, pale skin and dirty blonde hair. Her lips were full, as was her ample chest.
He reached down and began to pull her pajama top up. As the top came off, he saw her perfect breasts and knew he would never get bored of them. They were a C cup and sat so perkily on her chest. Her nipples hardened in the cold. He reached down and squeezed the right one, feeling how it moulded in his hand as his cock began to stir. He twisted the nipple and then got on the floor beside the sofa. He leaned over and took her nipple into his mouth, running his tongue around it and sucking on it. His cock was quickly growing to its full size, and he needed to release it.
Jack stood up and removed his joggers and boxers in one motion. His cock sprang up and stood proudly in front of him. He knew from experience now not to rush things, as it could all be over too soon, and he wanted to savour her. Plus, the serum allowed him plenty of time to fulfil his full desires. He moved Lily on the sofa and positioned himself so he was straddling her chest. He put his cock between her breasts and pushed them together. Jack had never understood fucking a woman's breasts from watching porn, but he loved to do it to Lily. Something about being able to feel them around him and see her beautiful face as well. He began to hump them, spitting on them as much as possible to lube them up. Her breasts were shiny from spit, and he slipped between them easily. They weren't quite big enough to engulf him fully, but the feeling of his cock sliding between them was incredible. Jack slowed himself down and looked at her lips. They were so full and inviting, and he knew her tongue was so sexy. Just like most teenage girls these days, Lily insisted on taking photos with her tongue stuck out. The first time Jack had seen this, he had rolled his eyes, but then he noticed how pretty it was. It was so pink and slick. So inviting. Jack reached forward and tried to open her mouth, running his fingers along her lips and trying to open them, but to no luck. He then held her nose shut, and after ten seconds, her mouth opened a bit to breathe. Jack pushed his fingers in and moaned as he felt her soft, wet tongue slide along his fingers. He moved himself up, keeping his fingers in there, and slid his cock in as well. Once the head was in, he removed his fingers, and her mouth shut around him. He was groaning, and the sensation was amazing. He imagined how good it would feel to have her sucking and swirling her tongue, but he knew he would never feel that. Instead, he pushed his cock forward, savouring the feeling of the warmth and wetness. He pushed in and out until half his cock was in her mouth. He felt her tongue move as she began to react, and he had to fight off the urge to come. He slid his cock out and slapped it on her face, loving how she looked so innocent. He smeared her spit and his pre-come over her and stroked his cock while running his head over her lips.
This was all becoming too much, and he knew he had to slow down. Jack got off Lily and moved his eyes down to her joggers. He tugged at the waistband and pulled them off with her panties. Once they were off, he looked at her mound and found that she hadn't shaved. It was furry with dirty blonde hairs, just how he liked it. He lifted her right leg and moved it to the side, and his mouth watered as her pussy lips split apart, showing him her inner folds. He moved the left leg apart as well and saw all of her. He could see her little clit hidden in its hood, her lips sticking out just a touch, and a slight hint of her hole. He knelt down and breathed her in. The smell was intoxicating, and his cock throbbed uncontrollably. He ran his tongue around her clit and continued to do this for a few minutes. He ate her pussy like it was the last meal on earth, and the taste was divine. He moved his face away and put two fingers against her hole. He had achieved what he was looking for as she was soaking wet. Her juices were almost running out of her, and he slipped two fingers in with ease. Getting her this wet was vital, as she was unbelievably tight.
Jack then ran his fingers along her from her clit to her hole to gather up as much of the wetness as he could. He then took it and circled it around her ass, spitting on it for good measure. He pushed two fingers into her. It was the first hole he had penetrated, and his fingers still struggled to push past her tight entrance. Her ring was hot and so tight that he struggled to work his way in. Once he was past her entrance, he worked them further up to the knuckles. Jack marvelled at how she seemed to squeeze on them. As he pulled them out and pushed them in, he remembered the first time he had ever fucked her ass, and the memory made his cock throb so hard he thought it might explode.

Jack removed his fingers and watched as her puckered hole gaped slightly for a second and then closed up. It was a beautiful sight. Jack then knew he had to fuck her. He twisted her so that it looked as if she was just sitting on the sofa. He then knelt in front of her and pulled her hips down toward him so she slumped. He then pushed her legs back and to the sides so she was presented to him. Her mound looked amazing in this position. It was like her mother's—quite pronounced and covered in fine hair that would look great matted with his come. He kept one hand holding her left leg and held his cock in the other. He placed it onto her pussy and humped gently forward so it ran between her plump lips and past her clit. The sight made him throb, and a small amount of pre-come came out. He used it to moisten her further and then guided his cock toward her hole. He lined up and pushed in. He had fucked her multiple times now; however, she was still incredibly tight, and it was a struggle. Jack did short thrusts and began working his cock in and out an inch at a time until he was halfway in. The pressure was getting too much, and he struggled to keep control. His brain was screaming to fuck her with everything he had, and the feeling of her pussy walls rippling on him was making it all the harder. He finally lost the battle and shoved the rest of his cock in. It hurt a touch, but it was worth it to see himself buried in her tight, teenage pussy. He began to fuck her, slowly at first but steadily increasing the power and ferocity of his strokes. Her head had slumped to the side, and her tits bounced with his motion. He reached up and squeezed them both hard, pulling her nipples as he lost control. Jack was now fucking her—not just having sex with Lily but fucking her. He panted and groaned as he felt her wetness increase, and he could swear that her pussy was trying to milk him. His brain began to fog; however, a voice inside him rang through, and he managed to force himself to slow down to a stop. He stayed motionless, but his cock kept throbbing, which was bringing him still closer to a climax. He begrudgingly pulled himself out of her. He desperately wanted to fill her with his seed, but he knew he had to have her in his favourite position.
He stood up and began to manoeuvre her body so that she was bent over the arm of the sofa. Her knees were still on the sofa cushion, and her body lay over the arm with her head hanging off the side. He pushed and moved her until she was in the perfect position. Her plump ass was presented to him, and he stood back and marveled. Kate's ass was by far her best physical feature, and she had passed this down to Lily. It wasn't huge; however, it was very shapely, and she had two well-formed cheeks that felt and looked amazing. He reached out with both hands and massaged them, splitting them apart. He loved how her pussy spread open and her asshole stretched when he did this. He leaned forward and buried his head in her again, but this time tongued her ass. It was tight, and he pushed his tongue in. It tasted of the pussy juice that had been running down between her cheeks while he fucked her. He pulled away and looked at her. Her back was moving from her relaxed breathing, and he felt so lucky to have found a way to enjoy the pleasures of her body.
Jack moved himself up and lined his cock up with her hole and pushed in. She was used to his size now and he slipped in easily, but he still enjoyed the feeling of her tight passage. He gripped her hips and began to fuck again. Enough time had passed that he wouldn't come too soon, and he enjoyed grabbing handfuls of her ass cheeks and pulling her onto his cock. He watched her asshole as he fucked her and spat down on it, hitting it directly in the center. He then pushed his thumb into her, and the combination of sensations—her pussy around his cock and her tight anus grasping his thumb for dear life—was divine. He took his thumb out and replaced it with two of his fingers, fucking her ass with them, imagining how it would feel to double penetrate her. He slipped his cock out of her pussy and spat on her asshole again. He then lined his cock up and pushed in. It was his favourite hole because of the taboo. He could never get over the idea that he was fucking his unconscious, drugged, teen stepdaughter's asshole, and the whole thing was too much for him. He pushed his entire length into her ass in one movement. It was hard, and he gripped her hips and groaned as she swallowed him. He rested with his balls against her pussy lips and then began to fuck. Every time he got to the head of his cock, her asshole would try to push him out. He loved the feeling, however, and when her ring finally relaxed, he felt a sense of accomplishment. She had submitted to him unknowingly, and he fucked her relentlessly. He was getting closer and closer as he pulled her hair and grasped her cheeks. At the very last second, as he felt his balls boil and the cum surge up his shaft, Jack pulled out. He stroked his cock and aimed at her gaped ass. He shot load after load into her as her asshole closed slowly, and his head went light at the sheer size of the orgasm. Jack wasn't quiet, as he didn't need to be, and moaned loudly. He leaned back and shot the rest on her pussy. It was slightly pushed together, and his cum hit her lips and dribbled down.
When Jack had come down from his orgasmic high, he looked at her. Lily was a mess—covered in come and juices. He got off the sofa and took her to get cleaned up, wiping her down gently to make sure there was no evidence. He then dressed her again and placed her back on the sofa to wake up where she had fallen asleep. In the past, Jack would have worried about the morning; however, he was experienced now and knew she would wake up fine with absolutely no memory of the event. The problem was that Jack remembered it all, from the first time to now, and he was well and truly addicted.
