It was about then that the bombshell was dropped that Anna didn’t actually have a spare room and no sofa so the three of us were going to be in the ...same bed. Anna slept in the middle and Karl on the opposite side of her from me and we all kept our underwear on. Needless to say I was a little disappointed and couldn't resist trying it on a little with Anna when I heard Karl snoring within minutes of his head hitting the pillow. She resisted my efforts telling me she didn’t want to do it with her. Then she started sucking my nipple and my cock was in her hand and I have broke her tops and bra then hunt for her butter boobs it was smelling a smooth blossom haaaaaa I have taken her 34 boobs inside my mouth I was sucking her like anything and she was nearly to cry because of enjoyment and she removed my hard rods skin and now we both are fully naked and she told me such a big cock I want all my dear brother it was encouraging me a lot.I went to her vagina haaaa super shaved butter vagina. This must have been how addicts felt when they snorted cocaine.My mouth reached the point where my thumb was still torturing Annie’s clit. I pushed her clit up with my thumb and did my best to lick it while resuming the in/out motion with my other fingers.“Oh fuuuck…don’t stop!” she said. Like I could at this point.I climbed between my sister’s legs and got down on my knees. As I pulled my fingers out of her pussy I reached under her thighs and lifted her legs onto my shoulders. I moved my face. I was trained on her ass the whole time as she got to the door and opened it. On the other side of the door was my fuckbuddy. Apparently she was her daughter's babysitter. I instantly ducked down to avoid eye contact or the chances of being noticed. After a while of them talking, I heard her come back out. "My babysitter took my daughter out for a few hours. How about you dry up and join me on the couch for some wine?". I quickly dried up, put my underwear and pants back on. But kept my shirt.
