[MF] [F] Her Sister Watched Us

This story happened during one night where Jess and I had been going out to a show, and her sister Shelly had tagged along with us. Shelly was eighteen and quite frankly a brat most of the time, especially to her sister and I, however at their mother’s behest I had agreed to take her with us for the show. Shelly was similar in size and shape to her sister, but chubbier, longer hair and bigger boobs. She was notoriously promiscuous and dressed accordingly, tonight she had on tight black leggings and a leopard print tank top that barely contained her DDD chest. Pierced nose, pierced lip, pierced eyebrow, and dark makeup completed her look.
After the show it wasn’t too late in the evening and Shelly wasn’t eager to get home just as I wasn’t eager to finish my night without fucking my girlfriend, so we stopped at my house for a bit. We headed up to my room and Shelly sat in my desk chair and started to mess around on her phone as Jess coaxed me into making out on the bed. After a little while, and without looking up from her phone I hear Shelly say, “Look, you guys can go ahead and fuck already, I’m gonna put my headphones in and turn around.” She did so and being the horny young adults we were, we took the opportunity.

With my back to Shelly, I stripped Jess’s jeans off of her and pushed them off the end of the bed, revealing her already wet pussy underneath, as she wasn’t wearing any underwear. I quickly put my mouth to her and began licking her juices and felt her fingers lace into my hair as she pushed my head down into her warm wet slit. I felt myself swell and grow in my own jeans as I ran my tongue around her hole, slipping one finger, then two inside her as I pressed my tongue to her clit. I started to caress the sweet spot at the top inside her as I licked and before long she tensed up, trying to push me off as she shivered through her orgasm, as I continued to lick her for a few seconds more to keep her riding that wave. I stood up and dropped my own pants and underwear to the floor and quickly mounted her missionary and pressed my throbbing cock against her slippery lips and immediately slipped inside her with no resistance. She let out a moan as I felt my entire shaft bury inside her and began to thrust slowly then faster and faster. I was gasping and moaning as she rubbed her clit as I fucked her and I could already feel the heat rising in my face and the tightness in my balls. “I want you to bend me over,” Jess gasped, doggy was one of out favorite ways to finish so I was eager to oblige.
As we stood up for her to assume the position, we both turned to see that the desk chair was no longer facing away, and suddenly we were both staring at Shelly, who had her hand in her leggings visibly playing with her pussy as she watched. “Not a bad cock for a ginger, and it looks like you know how to use it,” she smirked at me, and I looked at Jess for some sort of reaction. “She’s already seen it all now, just hurry up and fuck me.” She apparently didn’t care enough to fight the situation, as she got on her knees on the bed. If no one else was going to care, neither was I, so I grabbed a handful of Jess’s ass as she grabbed the headboard and pushed myself back inside her.

Now giving Shelly a visible show, I watched as she slid her leggings down her wide hips to give her free access to her shaved bare pussy, glistening in the light. I started to thrust into Jess from behind as I tried to keep my eyes away from her sister but besides the sounds of skin slapping and my cock squelching inside her, there was another wet sound coming from the desk chair. I turned my head to see Shelly leaned back with three fingers inside her as she furiously pinched and rubbed her clit. She was breathing hard as she watched us fuck and soon her eyes were closed as she appeared to put all her focus into fucking herself silly. I could feel myself ready to burst watching this unfold, and as I continued to grab and slap Jess’s ass I heard between her moans, “fill me.” And I did. I let go and came inside her and let out a gasping moan as I felt the cum erupt from me, filling her warm wet pussy with my load. Shelly began to shake in the chair and suddenly squealed and I knew she was cumming herself, when suddenly I watched a stream of liquid shoot halfway from the chair to the bed. Shelly let out a long moan of relief and sat back with her eyes closed for a second before opening them to look at us. I pulled out of Jess and my cum came rushing out of her pussy and onto the sheets. I sat on the bed staring between the two of them as Shelly grabbed a nearby tissue and wiped her crotch before she stood up and pulled up her leggings. Jess did the same as she started to clean herself before commenting nonchalantly, “so you squirt?”
“Fuck yeah I do”, was her response with a smirk again on her face. “Your boyfriend looks jealous of it.”

“More surprised, but I guess it just means you enjoyed the show just as much,” I replied.
“Don’t get used to it,” Shelly quickly fired back, “this ain’t no regular thing.”

Jess and I were in silent agreement, but no one could deny it was a surprising exchange we all enjoyed. We cleaned up and dressed and I drove them home, I walked them to the door and met their mother in the doorway. Shelly quickly walked inside and to her room, as I was about to say goodnight to Jess, her mom looked and me and asked “Everyone have a good time tonight?”

“Yes we did,” I replied, “yes we did.”

  1. Was almost expecting that one sister cleaned up the other or Shelly cleaned you up.
