Little Sister’s First Gangbang

It was a week after my high school graduation, and my parents were away. So, of course, I threw a party. Nothing big – about 10 of us, equal parts boys and girls – and a lot of alcohol and pot. I was standing in the corner by the stairs with my girlfriend, Jenn.

“Hey,” she said. “Wanna make a bet?”

“Depends,” I replied. “What is it?”

“I bet you that I’m going to fist Kelly by tomorrow morning,” she said, gesturing to a short, thin redhead currently engaged in talking to someone else.

“If I win?” I asked.

“You get to join in,” she said with a smile.

“And if I lose?”

“You have to pin her to the ground while I rape her with my fist.” This is one of the reasons I’m with Jenn – she has an evil sadistic streak. It kept our sex life fun.

“Done,” I said.

I saw movement out of the corner of my eye. It was my little sister Mandy coming down the steps. Shit, I forgot she was in her room.

“Where do you think you’re going?” I demanded.

“It sounded like fun down here, and I was wondering if I could join in,” she replied.

Jenn looked at me. “I think we could have some fun with this.”

Mandy was starting to go through her rebellious stage. In her, it manifested as a mall goth. Tons of eyeliner. Fishnet arm warmers. Black baggy pants with chains and a thick belt. Her hair matched the rest of her black outfit, although there was a little bit of blonde peeking out at the roots. At 14, she was just starting to develop sexually, so her breasts were little more than an A cup, and she rarely wore a bra.

“Alright,” Jenn said. “Let’s get you loosened up first.” She put her arm around Mandy’s shoulders and led her to the kitchen table that was serving as a bar. Jenn poured three shot glasses of tequila, and lined them up on the edge of the table. “You have to drink these.”

Mandy had never drank before, except for a glass of champagne at their cousin’s wedding. “Well, that will certainly loosen me up a bit.”

“Wait!” I yelled. “I’ve got an idea.” I ran out of the room and upstairs into our parents’ bathroom. I opened the medicine cabinet, took my mom’s bottle of Xanax, and poured one into my hand. I put the bottle back and made my way back to the kitchen. I poured a glass of water and brought it over to my sister, my hand open so she could see the pill.

“What is that?” she asked.

“Just take it. Trust me,” I answered. She downed the pill with a sip of water. “Okay, now drink the tequila,” I ordered. She made a face at the first shot. She gagged on the second. On the third, she almost spit it out, but managed to choke it down.

“How do you feel?” Jenn asked.

“Good,” said Mandy. “Really good. But wobbly.”

“Let’s do a little sobriety test. Bet you can’t walk a straight line from here to the door.” Mandy puffed up and looked determined, setting her eyes on the door, and carefully put one foot in front of the other. She wavered, trying to find her balance, on every step. Halfway across the room, she tripped over her own feet and fell to the ground, laughing.

“Good, you’re nice and drunk,” said Jenn. “That will make what’s going to happen next so much easier.” She grabbed Mandy by the arm and led her to the living room, where everyone else was. “Alright!” she yelled, pushing Mandy in front of her. Everyone went quiet and stared at the two of them. “There’s someone here who wants to party with the cool kids. But first, she has to prove she’s cool enough.”

“What do you want me to do?” asked Mandy.

“Take off your shirt,” demanded Jenn.

“But I’m not wearing anything underneath”

“I know. Do it.”

Mandy hesitated. She had never let a guy see her tits before. Hell, she’d only kissed two guys, and one of them didn’t count because he was gay. She felt a flutter in her chest and a wetness in her pussy at the thought of several guys staring at her tits.
