I crawled up a trellis and through the window into Bridgitte's room. She held the curtains for me, wearing a pair of plaid PJ pants and a loose t-shirt. The room had lots of frilly stuff. It wasn't big, just enough for a pair of bunk beds, a little makeup table and a loveseat facing the bunks.
"Oooohhh, so that's Bridgitte's new boy," said a female voice from the top bunk.
"Ugh, shut up!" Bridgitte hissed at the top bunk. In the dim light, I could barely see another face that looked exactly like Bridgitte's. "That's my twin sister, Gidget," she said to me. "We have to stay here around my annoying sister; I don't have anything close to privacy anywhere else in this house."
"So I get to watch her give head to her new freshman boyfriend," Gidget giggled from the top bunk. Bridgitte rolled her eyes. Her sister continued, "She's totally going to suck you. You actually look cute enough that I would suck you."
"Shut up!" Bridgitte hissed again as she pushed me to sit on the loveseat and started undoing my pants. "You know we don't talk when the other one is having sex." Gidget smirked. "And look away," but Gidget didn't listen.
So, "Nice cock!" was the twin's response when my dick came out. "That's bigger than what's-his-name's."
Bridgitte gave an exasperated sigh, unselfconsciously pulled her shirt over her head and off, revealing her shapely tits and delicately muscled frame. Then she bent down to start sucking my cock, cradling my balls as her head bobbed up and down. She hardly gagged as I hit the back of her throat. I had my hand resting on her head so, when her sister said, "I bet you wish I would come down there so we could both suck you like some porno about twins," I was able to hold her head down so she couldn't pull off and talk back.
"Yeah, come do that," I said, again reacting to keep Bridgitte from pulling off my cock.
"What's in it for me?" Gidget said playfully.
"I'll make your sister eat you out while I fuck her." Gidget gasped, obviously not expecting that answer.
Bridgitte pulled up so hard that I had to use both hands to push her down, forcing her to deep throat the entirety of my cock, making her choke and gag, her hands flying up, which made me cum. Then I let her up. Bridgitte, dropping to sit beside me, her nipples rock hard, practically shouted, "I will not! That's disgusting."
"Shhh!" Gidget shushed. "Mom and dad are sleeping," she hissed.
"That's disgusting!" Bridgitte repeated in a hiss. I just stared at her. "You can't make me!"
I frowned. "Then I won't fuck you," I said matter-of-factly.
"Whu...?" Bridgitte began, obviously not expecting to be told no.
"Take off your pants," I said, and the older girl did as she was told. Her black haired pussy, her clit and swollen labia, and ass, tight and muscular, round and soft, were bare now. "Turn around and get on your elbows and knees." Crawling down onto the carpeted floor, she obeyed, her head down and ass up. "Come down here, twin sister," I said to the top bunk. Gidget, her face looking surprised and shocked, also did as she was told, doffing her matching pants and shirt as she clambered down. She was definitely a twin, her body almost an exact match for her sister's. "On your back," I gestured to the spot in front of Bridgitte's face. She did that too, then, without being told, opened her legs to expose her pussy. It looked exactly like her sister's, pale, tight, black bush. She was obviously very wet and her clit was swollen. Gidget scooted until her own swollen cunt was right under her sister's nose. She still looked dubious, like she didn't believe I could make her sister do this, and uncertain whether she wanted her to. "Eat it," I said to the girl on all fours in front of me, pushing her head towards her twin's pussy as I lined my cock up with her own snatch.
Bridgitte pushed my hand away, then stared menacingly at her sister when Gidget repeated, "Yeah, eat it." But then Bridgitte, my thrall whether she knew it or not, dipped her head down and started licking her sister's clit, pushing two fingers into the gaping wet hole. Once she gave in, Bridgitte relaxed, eyes closed, working her sister's pussy. Gidget stared at her sister in surprise, then closed her own eyes, her head lolling back, hand holding her sister's head, her breasts with their own rock hard nipples rising and falling in time with her muscular abs. "Oh, God, sis, you're good at this. If I'd known, I would have had you eat my pussy long ago."
Bridgitte started to raise her head but I just slapped her ass hard and said, "Ignore her. Or, at least, ignore what she says. But make her cum," and my hips were pounding the brunette's muscular little ass. She was tight, her cunt holding my cock, massaging it. She was so wet; I knew the incest was turning my girlfriend on whether she wanted it or not.
Lubed enough, I grunted as my cock entered the familiar territory of the cheerleader's back door. Used by me in the past, the rectum was still a ring around my cock, massaging it. Gidget came shortly after that...and then again. And then, switching holes, I was pulling myself by Bridgitte's hips deep in her pussy, my hips slapping against her fit buttcheeks. I realized she had snuck a finger down to get herself off. So, the two of us came at the same time. I was howling, holding myself into her with one hand on her thigh, balls deep in her pussy, while I shoved her head down hard, keeping her face in her sister's pussy, her moans muffled by the hairy wet snatch. The three of us fell our separate ways, naked and sweaty. I looked at Gidget. "Now it's your turn."
Gidget looked at me with surprise, but she surely should have seen this coming. "What?"
"Eat my cum out of your sister's pussy while I fuck you."
"I will not."
