My First Time

Back when I was 16 I went with some guys to a party at a house in the burbs. The guys had two rooms labeled slut 1 and slut 2. The lights were out, the girls were blindfolded and naked. My friend went into slut 1 and I took slut 2. I'd never been laid before so I was nervous but I wanted to get some pussy. She asked if I wanted sucked first, then she laid back and I put my cock to her lips and after finding what she wanted she sucked me hard. I shot off in her mouth in a minute. She said she wouldn't say anything and to wait for a bit. She then started sucking me and in about 10 minutes I was hard again. She was very chubby, big, really big titties, 2 inch wide areola and nice hard nipples that were just a little pinker than her skin. She had a shaved pussy and she spread out, I got between her legs and when I started rapid fire fucking, and slipping out (she'd had cum all over her and the bed) she pulled up her legs and wrapped her feet behind my ass cheeks and held me in. I slowed down and kissing her tits, and even her feeling my way up to her face, I fucked her about 20 minutes and shot my load. I wiped my cock and balls and left her laying there spread out for the next guy.

My parents were away for the weekend, and the next day about 10 in the morning my sister comes into my room and jostles me awake. She is 2 years older than me and always gave me shit, but this time, I look up and she is standing there naked.
"Did you know it was me when you fucked me last night?" she asked.
"Yeah"
"How did you know"
"Your voice, and I saw you when I opened the door coming in and leaving, and I've seen you in the shower sometimes"
She pulled the covers off me, and sat down next to me, grabbing my naked cock.
"Did you like it? " She asked. Adding "You knew it was your sister you were fucking, did you like it?"
"Yes, a lot, it felt really good"
"Was that your first time?"

I told her it was, as sad as I was to admit it. She told me she thought it was me when I started talking when I was fucking her. In the middle of my hemming and hawing, she stradled me and stuck one of her big chubby tits in my mouth. I started sucking. She switched, then brought her pussy up to my mouth and told me, not asked, told me to lick her pussy. She showed me how to lick her all over, then concentrate on her clit. All the while she was jacking on my cock, I wanted her again and I told her.
"Not till I cum" she said
She told me she hadn't cum but three times the whole evening getting fucked all night. She wanted it, and wanted it now. She came three times, then got on top of me riding my cock with me playing with her tits. She started cumming again and leaned over and kissed me and I came too.
"Cumming in your sisters pussy. . . you like it don't you"
I could barely talk but uttered a "yeah".

That started my early sexual education. We still fuck a lot, we both live together, she did stop going to get gangbanged but still fucks around with a lot of guys. Most of the time I add my cum in her sloppy pussy and clean her out. I've also gotten her ass which she said no one ever did but me.

I know it will end sometime, but not for a while hopefully.
