Sandra wasn't sure it had even happened. After a drunken night on the town with friends, she and her brother had staggered home together and drank even more. The details of much of the night and early morning were vague, but she was sure she'd touched his erect cock, her t-shirt was inside out and back to front, and she wasn't wearing a bra. She desperately hoped it was a dream, or at least a silly game. Had she... An image kept invading her head. Her brother's cock, in her mouth.
No. Not possible. Maybe another boy came home with them. Still not a pleasant thought, sucking off a stranger, but easier to deal with than if it was her brother. She rolled over and timidly lifted the bed covers away from her face.
What the...? Why's the window over there? Oh shit. This is mum's room.
There was no panic, their mother would be away at Aunt Sarah's for another week. Then the bed moved. She wanted to know who she'd brought home and looked back over her shoulder. She wasn't sure whether to be pleased or shocked when she saw Jimmy's sleeping face. Her brother was snoring lightly. She knew she hadn't dragged a stranger home, but still there were those persistent images about... doing things ... with Jimmy.
In the warmth of mid-morning, Jimmy had kicked the covers away and was barely covered by a sheet. Sandra had a mad idea. In the dream - if it was a dream - the cock she had sucked had a dollar-sized brown birthmark beside it, reaching to the groin.
So she gently lifted the sheet, looked, and her heart stopped. Not only was the birthmark there, another detail flashed into her head -
Oh fuck. I remember now. He's got no pubes.
A phrase penetrated her shocked memory, one she'd said last night:
Wow, bro! A shaved cock, and so big too!
She felt sick. She wanted to scream at him, run away. As she tried to sneak out of the bed, two things stopped her. One was Jimmy snorting to wakefulness, bleary-eyed and trying to focus, the other was the realisation that she had no panties on. Jimmy looked across and he too jerked into some form of realisation.
"Oh fuck, Sandy. What did we...?"
"I don't know!" She couldn't stop her eyes welling with tears. Jimmy's head slumped back onto the pillow, himself beginning to piece random images in his head. His protective side kicked in.
"Sandy. Sandra. It's OK. Please don't cry. I don't even know...what...if..."
He decided to try to bluff his way out and pretend that he remembered zero. But it came back quite clearly. Not how it started, but the image in his mind was quite distinct. Sandy was beside him, here in their mother's bed. She had pulled his boxers down and off in the lounge room, laughing, and said "Wow, bro! A shaved cock, and so big! Want me to suck it? Huh? You want your sister to suck your cock?".
She'd led him by the cock in here, they lay down, then his sister -
his sister! -
had lifted his cock, then she'd licked it, put it in her mouth, bobbed on it a few times. He remembered being too drunk to get hard. Sandra gave up after a minute, lay beside him, and soon both were drunk-asleep.
Sandy was curled up, clutching the covers, facing away from him. Jimmy's head hurt bad, but she needed him to be strong for her then. He reached over and touched her back.
"Sandy. I can't remember anything. I know this is weird, and I kinda think we got way too drunk last night, but nothing..."
She cut him off, sobbing: "I sucked your dick, Jimmy. I sucked my brother's dick."
"Oh. Um..."
"Jesus, you can't have forgotten that!"
"OK. No. I remember. But it was a second or two, like a joke or prank or something."
Silence. Sandra felt trapped. She had to leave this bed but being naked from the waist down prevented her. She could have asked him to duck under the covers, of course, and he would have done that for her, she knew. That wasn't the problem. She was trying through the fog to remember how the hell she'd lost her panties in the first place, and until she did she wasn't ready to admit she was bare-ass naked down there.
"Jimmy, did you, um, or did I... Who undressed me? I didn't wear this t-shirt out last night."
Jimmy remembered well but wasn't sure how much honesty his sister could bear at that moment. But his mouth blurted it out anyway: "You did. You were drunk, getting up in my face. I said something like 'I'd do you if you weren't my sister' and you started up with 'Oh really' and 'So why doncha try' and stuff and, well, you took your clothes off to tease me. Sorry. I put the t-shirt on you."
Jimmy listened. She was still facing away so he couldn't see her face, but she wasn't sobbing. She thought for a few moments, then said: "So why didn't you put my panties back on?"
"I tried. But, um..." He couldn't be
that
honest:
I couldn't because I wanted you to fall asleep so I could look at your pussy. While you slept. But I fell asleep too.
She seemed to accept what he'd said though. "OK. Sorry I was such a drunken tart."
"Sorry I was too drunk to stop you."
