Sami lived directly across the street. She was soaking wet."Can I come in, David?" Sami asked."Uh ... sure." I moved out of the way and she stepped in...to the entryway. I closed the door."It's wet out there," she said with a big shiver. Water dripped into a puddle on the linoleum. I would need to get a towel and wipe that up before Dad got home."I must have just missed the rain," I said.She shivered from the cold."Can I get you something?" I asked. I should do something but I wasn't sure. I said ok and felt my cock already standing up.We went to the room and I switched on the lights. But she switched it off, instead she threw open the curtains. It was drizzling outside and but there was some light coming in, courtesy the street lights.She sat on the bed and asked me do you really want to continue because I am your mother and if anyone gets news about it, we will be in lot of problems.I immediately came near to her and put my index finger on her mouth and replied and I do want to. I was about to put it on when he said, wait, put the dress down and just stand there, let me look at you baby girl. Huh? oh, ok, i said as i threw the dress back in the box and stood there with my nipples so hard. i was wearing cute red, skimpy, see-through panties, my pussy and legs were freshly shaved, i knew i looked incredibly hot, i knew he was checking me out like a guy checks out a girl they want to fuck, mmmmmmmmm. i blushed and smiled, he didn’t try to hide his bulge, he said, you are. I started to lick and kiss and suck one of her nipples, then did the same to the other. I then kissed her again. We stopped for a few moments, trying to process what had just happened. After a few minutes we agreed nobody would find out and it wouldn't change anything between us as friends - and I went down on her. I was really nervous and I could tell she was too, but as soon as my head was between her legs we both relaxed. I kissed the hot creases inbetween her legs, and rubbed her slightly.
