Going on Vacation Pt 6

When we got back to the cabin, I ran right to the bathroom to turn on the shower. It’s an old cabin and sometimes the hot water takes a bit to heat up. While I was waiting, I went back to the kitchen, where Aaron was making sandwiches for lunch. He made mine with turkey and cheese, a bit of mayo, and mustard. Yeah, I like mayo and mustard together. Don’t judge, it’s good! After we were done eating, the shower was warm, and I hopped in, calling out, “Aaron, let’s save water, get in here with me!” Yeah, I didn’t have to say that twice. Before I could say Jimmy cracked corn, he was in the shower.

“Oh, I forgot my loofah sponge at home. Guess I’ll just have to use my hands.” With that, I reached for the soap, purposely letting it get slippery and pop out of my hands. “Oops! Let me just get that!” With a little laugh, I bent over at the waist, showing him my ass, parting my legs so he could see up to my pussy. Before I could even stand up straight, he had me around the waist with one hand, and with the other started fingering me, skipping over using one finger and going straight to three. With the hand that was around my waist, he reached down and started rubbing on my clit, and I could feel his cock growing on my back. He curved his fingers in me, by now knowing where my g-spot was, and if he hadn’t been holding me up, I would have fallen over.

“Oh God Aaron, that feels so good! Don’t stop, don’t ever stop fucking me!”

“I won’t, you’re mine ‘til the end sis.”

He turned me, lifting me up, so my palms were on either side of my face, against the wall, and I was only bent a little at the waist. Then he slowly sank to his knees, kissing my body as he knelt. The back of my neck, then one shoulder, then the other. The middle of my spine, then where my back met my ass. Each ass cheek, and then his tongue replaced his fingers in my tunnel. I could feel him shoving his tongue as deep into me as it would go, still rubbing on my clit with his other hand. He started tapping on my clit, then pinching it softly between his fingers, at the same pace his tongue was darting in and out of me. It wasn’t long before I had an orgasm. I started to kneel down in front of him as he rose to standing, but he stopped me, holding me up against the wall.

“I just want to be inside you. I need you now!”

He bent me over and lined his cock up, I could feel the tip slowly enter me, and then he put his hands on my hips, holding me still while he slammed the rest of his massive cock into my tiny pussy. I started moaning, pushing back onto his cock with every forward thrust he made. I could feel every inch of him inside me, could feel his balls slapping me. He reached forward with his hand again, and twirled my little clit between his two fingers, while plowing into me from behind. He would come almost all the way out, and then slam back into me, using all his force. I held myself up, my hands plastered to the wall, in a daze of sensation. I was pushing back against him as fast as I could, and he was hammering forward with the speed that only a teenage boy having sex can muster. Then I heard a door close.

“Aaron? Lisa? Are you guys here? The convention got out sooner than we though and your dad and I wanted to know if you guys wanted to do something?” It was my mom!!

Aaron had stopped, freezing up in fear, but I looked over to the door, verified it was locked, and continued fucking myself on his cock, yelling out “Hey Mom, I’m in the shower, but Aaron is outside somewhere, probably playing Indian or something, you know how boys are. I just got in here, but I’ll try to make it quick!”

It made me so hot, knowing my mom was on the other side of the door and I was fucking my brother in the shower. I guess it turned Aaron on too, because he finally unfroze and started fucking me again, going so fast, hammering into me over and over, that I started cumming again.
