"Sindy, is everything okay in there?" Our mother's voice sounded from the other side of the closet door. Only a few inches of wood separated us from discovery. I hoped fervently that the pounding of my heart only sounded like bass drums in my head.
I suppose in retrospect that we should have called off the wager right then and there. It was a stupid bet to begin with and if our mom found out, there'd likely be no end to the repercussions. So the smart move would have been to step back and let Sindy respond to our mother calmly.
But I could see in Sindy's gaze as we stood almost cheek-to-cheek that if I quit now, she'd say I'd lost. I wasn't about to let her win on a technicality. So I wiggled my finger inside her and whispered, "Tell Mom you'll be down in a minute."

To understand how I wound up knuckle-deep inside my sister, it helps to understand that we're twins. Sindy is older by about six minutes, but basically we've grown up together, almost like a single unit at times. Mom even gave us similar names: Sindy and Simon.
We've always been preternaturally close. Even now, our bedrooms are connected by a shared bathroom. After a lifetime of that, we've seen a lot of each other. Sindy and I don't have as many barriers between us.
Being twins also makes us a bit competitive, too. There was always the impulse to prove who was stronger, faster, smarter, etc. As we got older and we developed different interests, that diminished somewhat. But it never went away.
Anywise, those dual factors had resulted in another one of our verbal one-upmanship tiffs. I can't even remember how it got started, but soon enough we were each exchanging verbal barbs about our respective sex lives.
Sindy always had the advantage here because she was unequivocally smoking hot. She'd always been pretty, but when puberty hit, my sister got a quadruple dose. By the time we were freshmen, she had the biggest tits frame in school and the gap has only increased since. With her tiny waist and slender frame combined with a cup size deep in the alphabet, she's been custom-ordering lingerie for years. Naturally this makes her popular with boys and girls alike, a fact she enjoys lording over me.
I, on the other hand, despite being athletic and toned, have had comparatively less success with the girls at school -- a fact that she also enjoys pointing out. I countered quality was more important than quantity, and round and round we went.
Things got heated when she hit below the belt. Sharing a bathroom as we do, Sindy is well aware that I am heftily endowed. Although she's never seen it in action, she has repeatedly speculated that at full arousal it must be so terrifyingly huge that I could never hope to pleasure a woman with it.
Since her speculation hit uncomfortably close to truth, I rather vehemently declared that I was quite skilled at pleasuring the fairer sex. I insisted that I routinely could get a date off using just finger and thumb.
Sindy doubted me. I doubled down. She suggested I prove it, perhaps as a joke. I was too fired up to care, so said I would. Both of us were too stubborn to back down. Thus did I wind up with my index finger buried deep inside Sindy's pussy.
Unfortunately, about a minute into our contest, our mom knocked on Sindy's door. We hid in Sindy's closet, but mom could tell Sindy was inside. Which brings us back to the start of our sordid tale: hiding and hoping Sindy could make our mother walk away without opening the closet door.
