What was slightly more alarming, was that theblonde girl had a tattoo on her left shoulder, that matched one onRick's shoulder exactly. With the real...zation of what was going onsetting in, Alexis screamed, waking the girl.She jumped up and screamed at Alexis, and it was a minute before theyboth stopped screaming."What was that all about?" The blonde looked up at Alexis, confused."What do you mean? Who the hell are you?" Alexis shot back at theblonde, backing away from the bed."I'm...I...I'm. The four of us had a nice dinner out on the deck as the evenings had become warmer. Riley, in her typical fashion as of late, was dressed in a short tennis skirt (no panties) and a white wife beater tank top. She was not wearing a bra, which allowed me to see her erect nipples standing out from her perky, D-cup, 18 year old tits. Her jet black hair was pulled into pigtails.

When I opened my eyes and turned around there she was on her staring at me, and she said “you shouldn’t waste such a tasty load”. Next thing I know it went crazy, I pull up my sweats and try to cover my self up, but she stared at my cock, it was awesome. She turned around walked into the room and sat down in the chair again; I then collected my thoughts and sat back down on the couch. Now she opened her legs, pulled her shorts to one side, and started fingering herself, then my fried walks. “Mu-um!” she said. “I was having a wank!”“A what?”“Oh, come on, Mum. Don’t tell me you don’t frig yourself off.”“Frig?”“You’re not joking, are you?”“Immy,” I said. “I don’t know what you’re talking about.”Immy got off the bed and came over to me and took both my hands in hers.“Mum, how do you cum?”“Cum?” I said. “I don’t. Women don’t.”“Where on Earth did you get that idea?”I wondered just where I did get that idea? I was brought up with it. My mother! She had drummed it into me that.
