Sister's Panty Boy

I was quietly wandering around my sister’s room, everybody was out of the house and I wanted to indulge myself in a new habit. About a month earlier, my sister ran naked across the hall not noticing I was just coming up the stairs. She’d just had a shower and decided to run quickly to her room hoping that nobody would see.  She was soaking wet from the shower and even though she was my sister, I thought she was fucking hot.
Later, I decided to have a shower myself and as I walked into the bathroom I saw her panties lying on top of the laundry basket. Straight away, the thoughts of Rachel (my sister) naked came back to mind and then I started to wonder what she’d look like in these. I picked them up and they felt wonderful, my cock was rock hard from thinking about her and without another thought I started stroking myself with the panties. They felt so good wrapped around my cock that I just had to put them on.

So there I was, in her room looking for something to wear and enjoy whilst everyone was out, when I found a black lacy pair of panties. I slipped them on and they were a perfect fit, my cock sprang up instantly so I lay down on her bed and started rubbing myself through them.
That’s when she walked in. I heard her just as she crept into the room and I panicked.  She was going to freak, I was sure of it.

“Hey little brother”
“Rachel, I...”
“Don’t worry they look pretty on you, but you really should ask before you borrow my things.”

I couldn’t believe she wasn’t mad, here I was in her panties and she was chiding me on my manners.
Rachel walked up and sat beside me on the bed, her hand resting on my thigh.

“So what were you doing before I caught you hmm?”
“I was just trying them on you know...”

Her hand slide up and gripped my cock through the panties.

“Nothing else?” she started stroking.
“Please don’t be mad...”
“Just do as I say Mike and it’ll be fine, now here take off my top and jeans. If you like my underwear so much I’m sure you’d like to see it on.”

I took her clothes off and gasped, she looked incredible. She hadn’t been wearing a bra and her breasts looked amazing, I knew she was a C cup and they were so perky. She was wearing nothing but a purple thong and she was hot.

“Now come here”

She pulled me towards her and started to kiss me, our hands were all over each other. I gently played with her nipples whilst she squeezed my ass. I couldn’t believe I was doing this with my sister. I felt her pushing my head a little so I lowered myself to suck one of her nipples into my mouth. She moaned quietly and started rubbing my cock through the panties. She went to lie on her bed and motioned for me to come towards her.
On the bed, I knelt between her legs and sucked the other nipple into my mouth, it wasn’t long until I felt her pushing on my head again though. I kissed down to her hips and moved her thong to the side.

“Go on Mike, eat your sister’s pussy.”

I started licking and sucking, not sure what to do at all. She tasted so good  and pretty soon she was moaning softly.

“You’re ass looks so hot like that Mike.”

Rachel sat up and pulled my head so I never stopped licking her, she leant forward and put her hand on the top of my panties. Slowly, she slid a finger down between my cheeks teasing my ass through the lace.
She’d never done this before and it felt incredible, I started pushing my ass up against her finger. I sucked her clit into my mouth and flicked my tongue across it, she moaned hard.

“Does somebody like that?”

I couldn’t answer; I just carried on eating her. She moved my panties aside and started pushing against my hole.  Just as she managed to slip one finger into me, she came. She was bucking wildly, pressing my head against her cunt and moaning. I hardly noticed, her finger felt so good inside me.

“Oh fuck, yes Mike! Keep going, I’m cumming.”

She collapsed on the bed, gasping stilling pushing her finger in and out of my ass. I was moaning now, it felt so good.

“Stay right where you are little brother” She said, getting up. I was on my hand and knees on the bed wondering what would come next. Rachel walked around me and got on the bed behind me. She ran her hands up and down my legs, pausing each time to tease my ass.

“Do you like me doing that Mike?”
“So so much”
“Well how about this?”

I felt her breathe on the back of my legs and then her tongue pushing into my ass. I’d never even heard people did this, it was amazing. Her tongue moved in and out of me and I couldn’t stop pushing up to meet her every time. She reached up between my legs and grabbed my cock, rubbing me through the panties.

“How’s that?”
“Mmm, please keep going Rach.”

She kept rubbing my cock but was now sat up behind me.

“My my, you do like me playing with your ass.”

She pushed two fingers of her other hand into my now well lubed ass. She was fucking me with her fingers whilst I moaned crazily, my head pressed down into the bed and my ass right up in the air.

“That’s right little brother, moan like the bitch you are.”
“Look at you in your cute little panties, what would your friends think?”
“Actually little brother, what would my friends think? Maybe we could have a little fun some other time...”

Instantly, thoughts of Rachel’s hot friends filled my head, how embarrassing it would be if they saw me like this. Strangely, the thought turned me on even more, I pushed harder against Rachel’s fingers.

“Oh you want my friends to see you like this? Kneeling on my bed, getting fingered like a girl?”
“Yes Rachel”
“Hmm well maybe I can sort something out, if you do as I say.”
“anything....”

Rachel started rubbing my cock harder through my panties and pushing her fingers deeper into my ass.

“I want you to tell me when you’re about to cum, because today’s your lucky day little brother. Today you get to cum on your sister, would you like that?”
“Oh God yes!”
“Mmm but there’s a catch, once you’ve cum you have to lick it all up.”

I was about to argue but the feeling I got from her hand and the lace on my cock was too much, I’d do anything she said. I was moaning loudly, I could feel myself getting close to cumming.

“You ready little brother?”
“Uhhhh....” it was all I could say.

Rachel slid under me and held my cock pointing at her stomach. She reached around and put a finger back in my ass, stroking my cock.

“Well come on, come on your sister’s sexy body, do it little brother!”

I couldn’t hold on for another second, I started cumming shooting it all over her chest and stomach until I collapsed on her. Rachel pulled her fingers out of my ass and let go of me.

“Well little brother, get eating.”
“But Rach, I don’t want to anymore!” There was no way I was licking that up now I’d came
“You will bitch! Or I’ll be telling mum what you’ve been up to and I certainly won’t be bringing my friends around to play with you...”
“Please Rach, don’t tell mum.” she had me, I had to keep her happy.
“Get to it bitch!”

I slowly lowered my head and started licking my cum off her tits, I nearly gagged the first time I tasted it.
“Good bitch, I’m sure a panty boy like you loves the taste of cum. Make sure you clean me up properly.”

I worked my way down, licking all my cum off her whilst she humiliated me. Once I’d finished she got me to stand up and take my bra off.

“Ok little brother, I want you to wear the panties for the rest of the day and remember from now on, you do whatever I say.”
