"This isn't gonna work," Suzy said.
I had broken my leg in a skiing accident two days before, and I needed help taking a shower, so being the good sister she is, Suzy offered to help me with bathing and to try and keep my cast dry.
"I have to come in there with you. It's just too damn hard to wash you from out here."
I stood in silence, staring at my sister's body as she revealed it to me. First the shirt over the head, then the bra. Watching her wiggle out of her drenched jeans made my limp, wet cock jump and start to stiffen. I tried to hide my growing erection by holding my hand between it and her, but as she pulled her panties off and stepped out of them and into the shower with me, she smiled and gently pulled my hand away.
"Don't be embarrassed little brother. I expected your little guy to wake up. You're in the shower with a naked woman." She looked at my erection for a few seconds and smiled.
"Wow. That aint no dick. That's a cock," she said, grabbing the bar of soap. She soaped up my cock and balls and rinsed them off. After she did the rest of my body, she worked up a good bunch of suds and told me to turn around.
"Bend over and brace yourself, hold on to the towel bar," she said.
I felt her hands soaping up my ass and ass crack, but I wasn't expecting what she did next. I felt her fingers slide down my ass cleavage until they came to my back entrance. A gentle massage right on my asshole. My cock was a steel girder.
"Do you want me to stop? A lot of guys don't like to be touched down there. Do you mind if I finger fuck you in your asshole?"
"Suzy, I appreciate you helping me out but you're my sister. This is incredibly awkward for me."
"So..,should I stop?"
I thought for a minute. Seemed like a very long minute.
"So?" she asked me again.
"Go ahead. But only if you let me do you later."
I felt one finger slide past my sphincter straight up my dirt hole. She wasted no time.
"What do you want to do to me?"
"You'll see soon enough," I said as she slid two fingers up into my rectum. She began to pump her fingers up inside me, and I involuntarily pushed back against her thrusts until we got a nice rhythm going.
"You like it up your ass don't you, little anal brother?" She started to go a little faster. I grabbed the towel bar and stuck my ass out
for her. Her hand was on my belly, but I felt her slide down to my aching cock.
"You seem to enjoy this. Maybe you'll like being pegged with my strap on later."
Fuck. I really liked her fingers inside of
me, but the thought of a dildo up my asshole made me hot as hell. I couldn't wait to get her alone in her bedroom.
"I'm gonna cum if you don't stop stroking my cock," I said.
"But see if you can squeeze another finger up my hole. If you want to ass fuck me with a dildo, I want to be stretched out good."
Next thing I felt was her fingers being removed from my anus, and then what I assume was the three fingered rape of my virgin asshole. Suzy grabbed me around the waist and slowly plunged what I assume was half her hand into my soapy, slippery back door until it was stretched to the max. As she force fucked my asshole, it really began to hurt. But strangely, I didn't want her to stop.
"Fuck me. Fuck my tight, virgin asshole Suzy. Fist your brother's asshole. Shove it in Suzy. Deeper! Get it in there!"
I screamed and groaned and screamed some more.
"Fuck me you bitch. Fist my tight little hole. Fuck me up to your elbow!"
