Sunday.
---
My sister Elizabeth's presence in the kitchen early the next morning had been flagged by the growing smell of nail varnish as I came downstairs. Sure enough, as I entered, wearing my father's bathrobe, there she was, sitting on a kitchen chair wearing her Hello Kitty nightshirt. She had one foot tucked next to her bottom on the seat, her chin was resting on her knee and she was engrossed in painting her toenails purple. As I moved over to the sink, I caught a glimpse of her panties, pale blue this morning, peeping out from between her legs. She looked up.
This was our first meeting since the events of last night, when Elizabeth had sat topless watching my girlfriend Keiko demonstrate a blowjob on me. My sister had even taken my cum into her mouth in a snowball swap, although she didn't swallow. She had seemed fine with it all, but that was last night; I didn't want this morning to be weird. Maybe Elizabeth was embarrassed; maybe she had regrets. I needed to give her the chance to bring normality back to our relationship -- if that's what she wanted.
"Morning," I said, as nonchalantly as I could, trying not to look at her underwear.
"Hey!" she said, enthusiastically. Perhaps too enthusiastically. "What do you think of these?"
Elizabeth stretched her leg out straight towards me and wiggled her freshly-painted toes. I now had a clearer view of her pale blue panties.
"Very purple," I remarked.
She laughed, placing her hands behind her head and leaning back, allowing her Hello Kitty nightshirt to pull taut across her perky nipples. If Elizabeth was feeling embarrassed about the events of last night, she certainly wasn't showing it. She raised her foot higher.
"Blow on them," she demanded, wiggling her toes again.
"What?" I muttered.
"The varnish is wet. You need to blow on them for me."
My mind was racing. I had planned to keep everything as normal as possible this morning. Last night had been an intensely erotic experience for me, but I couldn't let that cast a shadow over the rest of my week at the family house. Yet here was my sister, draped on a chair before me, blithely flashing her knickers and waving her cute bare foot, asking me to blow on her toes. Maybe this was normal for her. Maybe this is what regular brothers and sisters do. Being ten years older than Elizabeth, I had left home before she had grown interested in things like nail varnish, plus Keiko never wore it, so what did I know?
I reached out and gently cupped the heel of Elizabeth's foot. I was tempted to move it sideways, pushing my sister's legs wider apart to see how far she would go with that, but I resisted the urge. As it was, I could already see the gusset of her panties beginning to take on the shape of her pussy lips.
I leaned forward and blew gently on her foot. She giggled and wiggled her toes under my tickling breath. Our eyes met.
"What colour should I do the other foot?" She asked.
"Pale blue," I replied absent-mindedly, immediately regretting it.
Whether or not Elizabeth clocked the reference was not clear. She was obviously enjoying this moment, and possibly aware of the effect that she was having, as the front of my bathrobe was beginning to take on the shape of my growing erection.
"First blowjob of the day?" Keiko's voice broke the moment.
I quickly let go of Elizabeth's foot, as my half-Japanese girlfriend, fully-dressed, crossed the kitchen carrying a pile of dirty laundry, heading for the small utility room next-door.
"Don't let me stop you," she continued.
Keiko obviously shared none of my reservations about Elizabeth's state-of-mind this morning. True, the laundry task was cultivating an air of normality, but a reference to blowjobs in her first sentence was not. Keiko wasn't embarrassed for Elizabeth's sake, and certainly was not embarrassed herself. I still had a lot to learn about emotional maturity from these two women.
"Anything else for the wash?" Keiko's voice came from the utility room, where she could now be heard loading the washing machine.
Elizabeth pulled the top of her Hello Kitty nightshirt up to her nose, sniffed it and scowled. She then leant forwards to take her weight off the seat so that she could slip the hem of the nightshirt from under her. 'Was she really going to take it off here and now?' I thought. I could already tell that she had no bra on.
"No!" I called through to Keiko. "We're all good here."
Elizabeth stopped, sat back and grinned. These two girls already had me firmly on the back foot this morning and she knew it. It concerned me. I knew that when Keiko was in this mood, I had to be on my guard. What my sister was capable of was not yet clear to me.
"How did you sleep?" asked Keiko, as she returned to the kitchen.
"Really well!" replied Elizabeth.
"It was long evening for you, Sweetie. You must have been tired," continued Keiko, as she brushed the hair on the back of my sister's head with her hand. Elizabeth turned in her chair looked up at her.
"It was fun," she said.
"Good."
"I wish I'd swallowed your cum, though," Elizabeth added.
And there it was: a direct reference to last night's sexual activities. So much for my plan to avoid it! In reality though, the way these two girls' minds were set this morning, I had no chance. Typically unfazed, Keiko continued to stroke my sister's hair.
"My cum?"
"I mean Matthew's cum," Elizabeth corrected herself. "From your mouth."
"Why do you wish that?" asked Keiko.
As Elizabeth took a few moments to think about her response, she looked to me. I was acutely aware that the renewed twinge in my groin was in danger of developing into something more, so I turned to face the sink and began the fill the bowl with washing-up water for last night's glasses.
"I don't feel I got the full experience," answered Elizabeth.
"You still can."
I stopped my washing up. Talking, flirting and blowing on toes was one thing, but was Keiko now suggesting a continuation of last night? A pick up where we left off? Where would that lead? I chose to ignore Keiko's statement."
"Have you had breakfast yet?"
The girls laughed salaciously. I couldn't ignore that one. I needed to respond, but my already swelling cock had now been given a boost by the thought Elizabeth eating my cum for breakfast. I remained facing the sink, saying nothing.
"How about it, Matty?" enquired Keiko.
"No!" I quickly responded, washing the same wine glass for the sixth time. "We've already gone too far with this," I added.
"And Lizzie's already tasted your cum. She's not asking you to fuck her!"
I've long since learned not to fight Keiko when she's in this mood. Once her mind is set on something, that's it for her, so there's really no point in joining battle. To be honest, I wonder also whether I even wanted to fight this time. I quite liked the idea of seeing my cum in my sister's mouth again; watching it being drooled in by my girlfriend through a messy, cummy kiss.
But what if Elizabeth really had asked me to fuck her? What would I have done then? "It's just another demonstration," would doubtless have been Keiko's rationale, as she encouraged me to "give it a go" and "do it for your sister's sake." That really would be taking things too far, so I resolved to end it there and then.
