The next morning, I got up, cleaned up my dinner and without showering I went to do my planned chore, wash and wax my car, vacuum out the inside, clea... the windows, and then cut the grass. After putting away the tools, I went inside to shower about 2pm. The back door was open but my parent's neighborhood is quite safe so I didn't give it a thought. Hot water, shampoo, soap and the grass at my feet cascaded off of me.I don't know why I bothered closing the bathroom door when nobody was home. It did not take long and they were kissing. He soon had her top off and was feeling her bald pussy under her short leather skirt. She was almost coming just from his fingers in her pussy. He then stood in front of her and took off all his clothes except his underwear. He knows how much she loves to pull a big cock out and take it in her mouth. I can't express how horny it makes me to watch this. After a few minutes she took him to our bed where they spent two hours fucking and talking and. Once again I woke up next to my sister. I almost thought the night before was a dream. Did I really get my sister pregnant? Yes. I lifted up her shirt and felt her stomach as she woke up."What? You think the baby is gonna be kicking already?" Judy asked."No, just feeling around. I put my seed in there, I think I earned my right to feel around down there," I replied."Well I guess that's true. But don't make a big habit of it though," Judy said."And if I do?" I asked."Yeah, I got nothing, just. I moaned as her soft moist mouth engulfed the whole of my cock. Beth sucked me off like an expert, swallowing my whole length then popping the whole thing out of her mouth before taking it back in again. As she sucked my dick I moved my hands up under her skirt and pulled her panties to the side, so I could get a look at her pussy. "Mmmmmmf, mmmmmf, mmmmmf" Beth said as she worked my cock with her mouth.I was about to cum again."Give me your cum, baby, give it to me, let me taste it again" Beth.
