This story picks up the very next morning after part 1 and assumes you've already read how Kat started worming her way into Alex's head. Check that out first before you read on here...
I wake up the next morning, sticky with sweat... and not just sweat. I reach down and feel the cum coating my stomach. I also feel that I'm already hard, and not just morning wood. I take a long deep breath, remembering the frenzy of last night.
I had been ready to fuck my girlfriend's younger sister Kat, I had fingered her to an orgasm that... well that was why I was still hard. Having my girlfriend Allie call interrupted me from making an even bigger mistake. I managed to close myself into my bedroom, and as soon as she hung up I was stroking myself. I couldn't think about anything but Kat of course. Her delicious figure, her needy expression, her
scent
.
I came
hard
, with both my hands stroking my erection and pumping my need out of me. I must have fallen asleep after that, but I couldn't even say for sure. Awake now in a haze, I grab a tissue to do my best cleaning myself off and waiting for the erection to go down. I already know I'll have to give Kat an awkward apology today. But I can't do it while I have this massive tent in my shorts.
For that matter, I probably stink of sweat considering how stuffy I feel. I gather up some clothes for a shower, and then head out for the bathroom. But it's already occupied, I hear the hiss of water in the shower. Kat is obviously in there, soaping up her body. Washing away the sweat and wetness coating her after I manhandled her until she came.
My hand is down my shorts, teasing my cock and I stop myself. I hurriedly turn away. I leave my clean clothes to the side and head down for breakfast. Some coffee and food can help me clear my head, make me stop thinking about last night.
I get down to the kitchen and find that there's already a pot of coffee made. I sigh, rubbing my face and feeling guiltier as I pour out a cup. I then see Kat's even left out a slice of cake on a plate. I sip my coffee and sigh. Something about the gesture of her setting this out for me makes me feel grosser. That she's still being so nice after last night, well it means she's at least not too upset. It'll make it easier to apologise if she'll let me talk to her then.
I stare into space, running through what I can say to her, when I can't even explain it myself. Well at least I can admit I've always found her attractive, but that doesn't mean I'm a cheater... normally. But I don't know that I could explain what made me so different last night. I gulp my coffee, drinking it too fast the way I always do.
I pour myself a second cup, and take a forkful of the cake to get myself actually eating food and not just filling myself with caffeine. The cake tastes so good. As I take another sip, I get a hint of something that reminds me of the cake too. Maybe she spiced it with something? Regardless, they pair well. It's ridiculous that she could be single when she makes delicious stuff, and is so delicious herself.
I bite my lip, realising I'm letting my mind wander again. I need to be ready to talk through things with her and not start getting horny and lascivious when I'm trying to reassure her.
"Oh good morning," she says suddenly standing in the doorway and... she's just wearing a fucking towel. That juicy, squishy body of hers is dripping wet, right in front of me. And the towel covers her because she's short enough, but it could fall so easily. Or get ripped away.
"H-hi, thanks for the coffee," I quickly choke out to fill the silence. She nods slowly, eyes going from my plate, to the coffee cup and then the pot, "Oh uhm... if they were for me? I hope I didn't just take your breakfast."
"Oh no no, please eat it up," she shakes her head and approaches me, putting a reassuring hand on my arm. If I wasn't sitting, I'd have a high enough angle to see right down that towel. Something about the unfairness of that makes my toes curl.
"Thanks..." I exhale slowly, "Listen-"
She puts a finger to her lips and shakes her head, "Can I just talk first? Please."
I blink before nodding and I start drinking my coffee to make sure I don't interrupt with any stray thoughts.
"Last night, was amazing. And I know you have my sister, so I understand it was just a one time mistake. I'm sorry for what I did to encourage you, I got swept up in the moment and I've just
never
felt like that," she talks with a confidence she doesn't normally. The shy girl is keen to get her whole speech out.
"So uhm, I don't want to make you uncomfortable but I did want to thank you. I know we never can again but it hit nerves I didn't know I had."
My cup is empty as I set it down, my mouth hanging open as I watch her talk about me just using my fingers on her. Of all the questions running through my head, I ask, "was it really that good?"
"God yes," she bites her lip, cheeks flushing with the memory, "It's not like I've never orgasmed before but... not with anybody else. Just when I'm by myself, and it takes a LONG time," she shudders with the thought. And I'm rock hard at the idea of what might have happened if we'd gone further.
