Katie's mom invited Bill into the house, telling him that Katie should be ready to play shortly. As Bill made himself at home, Katie thought about what she could wear. She rushed to her room and tossed the towel aside in favor of digging through her closet. Should she wear a skirt? Boy shorts? Booty shorts? Or- she found it. She gets dressed and heads out to the living room, “Hey Billy!” She said with a grin. Bill frowned at the full use of his name, but gave pause to his retort as he eyed Katie. She was wearing a large hoodie, light blue in color and coming down to about mid thigh, however she wasn't wearing pants. Her mother simply assumed Katie was wearing shorts underneath as she usually did, but Katie has changed in the last few hours, becoming much more daring without her knowledge. “Hey Katie, sorry for suddenly just showing up.” Bill said, eying her exposed thighs and recalling where those legs ended. He shifted uncomfortably as his pants seemed to get tighter at the memory of her rubbing her cunt as she was covered in cum. “Katie, why didn't you tell me you made a new friend today?” Her mother asked as she set the table. “He certainly looks like a proper young man!” Katie rolls her eyes and sits down at the table, “Because you always try to assume I'm dating every boy I talk to, can't I just have a friend who's a guy?” “You know I'm just looking out for my only child, lots of strange boys out there.” She said, carefully alluding to possible dangers. Katie sighed and moaned, “Mooom!” “Fine fine,” she said, giving Katie a kiss on top of her head, “you're growing so fast and you're so responsible already, I just wish you wouldn't ruin all the nice clothes I get you.” She rolled her eyes again but didn't retort, it was an argument they had too many times already. “Anyway,” Katie's mom continued, “I hope you like stew Billy, I made plenty so feel free to help yourself! After dinner you guys can play your games but you'll have to head home at nine, alright?” She said, laying some ground rules. They both nodded and dug in, “Wow, this is some good stew Mrs. Katie!” Bill said, causing her to laugh at the new name. “As strange as it sounds, I do have a name you know!” She said. Katie grinned and quipped, “Yeah, your name is Mom!” She groaned dramatically, “Kids these days! Fine, you win.” They had a good laugh and finished up dinner before going to the living room. Katie's mom was in the kitchen cleaning up, giving them both a bit of privacy for the moment. “Want to play Mario Kart?” She asked him. Bill nodded, he came over not sure what to expect but so far he was having a good time regardless. “Yeah, that sounds fun! My older brother let me play his partner in Double Dash on the GameCube.” “Oh that super old one that came out forever ago that kids our age have never touched?” She said, looking into the camera. Bill looked in confusion between her and the wall she turned to look at, “What?” “Nothing, let me set up the Switch!” She said, moving to the TV stand. There she bent over, hiking her tail and the hem of her hoodie, showing off that she was actually bottomless this whole time! A hint of moisture was still present, the thrill of walking around bottomless without anyone knowing was quite the turn on. Bill's tent grew in his pants as he stared at her exposed rump. He thought to try to hide it, but after what happened earlier there wasn't much point in being coy or shy about it. She stood and turned around to see his impressive tent, “Here, you can use the spare controller!” She said, handing him the one with the loose thumbstick. “Gee thanks.” He said half-heartedly. “Oh and mom would freak out if she saw that, sooo….” She said, trailing off as she moved to sit in his lap. Bill tried to stop her but it was too late, she sat on his semi erect cock and it bent at an odd angle, he yipped painfully, causing her to jump back up, “Oh! I'm so sorry!” She said quickly, “I didn't think it would hurt!” “Ow ow ow…” Bill muttered as he unzipped his pants, freeing his member to relieve the pressure and the odd angle it was forced into. “That's better… and normally it's fine but when it's hard like that, if bent wrong it can really hurt.” Bill explained as he massaged his sore dick. “Oh, well regardless we can't let mom see that so I'll help hide it.” She said. This time she sat carefully in his lap, making sure his cock went between her thighs. Her pussy hotdogged around his cock as they pressed together, her hoodie covering their illicit acts. Just in time as well, as Katie's mother walked in from the kitchen. “Daww, you two are super cute together~!” She cooed, giving Katie a kiss on her head, “I'm going to lay down for a bit, you two have fun!” “Okay mom! We'll keep it down.” Katie responded, shifting around on Bill's cock as she spoke. “Thanks sweetie, have fun now!” She said before disappearing upstairs. Bill let out a breath he had been holding in a low moan, Katie's wet hot pussy was grinding on his cock pleasurabley. “Holy crap Katie, this feels amazing!” He whispered. Katie responded by rocking her hips, grinding her clit on his shaft and gasping quietly herself. “Y-yeah, keep it down though!” She said as she started the game. As they played, Katie would lean side to side as she turned and drifted, even going so far as to bounce on his cock when she got items or finished a lap. Bill was having a tough time, holding back moans of pleasure and trying to hump back as he also tried to actually play the game. Her pussy slipping and sliding over his cock was just too much to handle, and after only a single race he felt himself close to the edge. “K-Katie… I can't… hold on…” He grunted, his words though only encouraged her to grind harder. “Me too, let's do it together!” she whispered between breaths. It wasn't long before she pushed herself over the edge, her pussy quivered and clenched over his cock as she held her breath to keep from moaning out in pleasure, his cock getting even more soaked in her fluids. Bill let himself go, his cock twitching against her folds as he came, his cum splashing up against the inside of her hoodie and soaking into her thighs. After a moment to catch their breath they gave each other a warm smile and continued playing Mario Kart. As they played Bill's cock deflated and returned to its sheath. No longer distracted they were able to focus on the game and get lost in the competition, all the while Katie remained on his lap. After an hour of gaming the front door opened and Katie's father walked in. “Hey kiddo! I'm home!” He declared. “Hey daddy! I'm playing games with a friend!” She called back. They could hear as he set down various things, removed his boots and hung up the keys. “A friend huh?” He asked as he stepped into the living room. Bill started to panic internally as her father looked at them, Bill knew he couldn't see that his sheath was out and that Katie wasn't wearing anything, and as scary as being caught would be, the thrill of it made him excited. The tip of his cock started to emerge from his sheath as Katie spoke to her father. “Yep, this is Bill! I kicked his butt in football, now I'm kicking it in Mario Kart!” She said, and to prove her point she aimed and shot a green shell at Bill's character, knocking him off the track. Bill complained about it but stopped as he felt the tip of his cock pressing against Katie's rear, the familiar heat and moisture welcoming his cock. Katie also paused as she felt something poking up under her, and unlike before this was pressing directly against her entrance with steadily growing pressure. She had only discovered her entrance a bit ago and hadn't even put a finger in there past the first knuckle yet. “I see that!” Katie's dad said, sitting in the armchair and relaxing. “So Bill, you from around here then?” He asked as he loosened his tie. Bill tried not to moan or think about how his growing erection was steadily pushing its way into Katie's tight sex, “Um, yeah! T-turns out I'm only a few blocks away!” He held back a grunt as the tip pushed deeper into her. Katie's dad chuckled, “No need to be nervous bud!” He said, misinterpreting the situation. Katie gasped and moaned as the tip slipped deeper inside, breaking past her barriers and stretching her in ways she's never known before in a strange mixture of pain and pleasure. Her father gave her a quizzical look but she played it off, “I hit the wall, it looked like it hurt and caught me by surprise!” She said, trying to keep her breathing under control and holding back the tears. His cock kept slipping deeper inside her, she felt so full already and impossibility stretched but it kept going, deeper and deeper, pressing and stretching parts of herself she never knew about. “Ah I see, must be really into the game then!” Her dad said with a laugh. He stood up and gave her a kiss on her head, unaware his daughter is losing her virginity right in front of him. “I'm going to hit the shower, see you in a bit!” Bill watched him walk off, as soon as he was out of sight he whispered, “Holy cow I'm so sorry it just started happening and I-” Katie cut him off, “Don't stop, holy cow this is amazing!” She whispered back, grinding her hips as the last remnants of the pain faded to pleasure. Bill nodded, his worry for her well being cast aside with her reassurance and he too started shifting and pressing his hips against her. They bit their lips and moaned, their union more pleasurable than anything they had experienced before. Katie felt him deep inside, his cock pulsing as it became fully erect. She did her best to squeeze it with all her might, finding that the increased pressure felt even better. Bill moaned as she clenched down on his cock, the pleasure welling as her wet, velvety walls did their best to milk him dry. His breathing became labored as he quickly approached orgasm, Katie's walls twitched and clenched around his cock as she got close too. Suddenly her dad returned! They both froze in place, Bill's cock buried deeply in Katie's pussy, painting her womb with his seed. “Hey Katie, have you seen my spare shampoo?” He asked. Deep inside her, she felt Bill shudder as his cock pulsed, a hot warmth spreading and seeping through her core as she responded, “Um, under the sink, I think?” She managed just in time as her own orgasm shook through her body. She tried to maintain a neutral face as her body shuddered and she was rocked with pleasure, her pussy contracting and milking Bill's cock for everything it had. “Ah thanks kiddo!” Her dad said and ruffled her hair as she orgasmed without his knowledge. He soon vanished back into the bathroom and they both let out their withheld moans of pleasure. “God's, that felt even better Katie, what was that?” Bill asked as his orgasm ebbed. “Well, your penis is inside my vagina…” She said. She lifted the hoodie and leaned forward, letting him see his knot pressing against her pussy, the rest of his cock buried deep inside her, a mixture of their fluids slowly leaking out aroung his shaft. “Wow… I had no idea that was possible!” He said in awe. “Does it hurt?” Katied shrugged, “It did at first, but then it felt nice, then amazing.” Bill nodded, “Yeah, I thought you were hurt. I'm sorry again.” Katie slowly stood, Bill's deflating cock spilled out along with globs of cum and other fluids that spilled down Katie's thighs. “Ahh… so sensitive… but it felt amazing.” She said, turning around. She leaned down and without asking started licking his cock, cleaning up their fluids. Bill moaned but shuddered, he was still sensitive as she kept licking, even as his cock vanished back into his sheath. Katie licked his sheath clean then stood and licked her lips, “It's kinda tasty, you should do that into my mouth next time, okay?” She said with a smirk. Bill smiled back and zipped up his pants, “Yeah? I want to do the same and lick you too.” Katie nodded and leaned in, kissing him on the lips, letting him have a taste of the remaining mix of fluids on her mouth. They moaned as they shared their first kiss, as awkward as first kisses usually are. “Ah so you two are dating!” Her dad boomed out as he emerged from the bathroom. Quick as a flash Bill and Katie separated and denied, “No we’re not!” Her dad laughed uproariously, “Uh huh, and that wasn't a kiss I saw?” He teased, enjoying their embarrassment. Thankfully for them, Bill had zipped up and Katie's hoodie was long enough to cover the evidence soaking into her thighs. Bill muttered an excuse and dashed out of the house, fleeing from the embarrassment. Katie did about the same, except she dashed past her dad to her bedroom and locked the door. She leaned against it and caught her breath, the last few hours running though her head as her hand trailed between her thighs, gathering the leaking fluids onto her fingers. She played with the stringy cum as she thought about actually being in a relationship with Bill, she certainly enjoyed his company, even when they weren't being lewd she certainly had fun, and he was nice. She stuck her fingers in her mouth, licking them clean of cum and fluids. She decided, they were certainly dating now, and she looked forward to even more shenanigans.
