.. I mean, you were... um. I was having sex with you." Like how Sam? Were you playing with my tits? You like my tits?" Yeah, um, I like your tits. I m...an, breasts, um..."I started lifting up my sweater and I pulled it over my head and undid my bra as he just stared."You can touch them Sam."He reached down and started fondling my tits. "Do you like my ass Sam?" Uh yeah, you have a great ass ma'am." Thank you. Now, you've seen my tits. I want to see your cock Sam. Whip it out for me."He reached. So back to story, I pulled his underwear from his back while lungi was still on and that was the first time I touched his bare butts. You wont believe it but I got a hard on immediately and his butts were so smooth and not a single scar or hair. Just like I was touching a piece of marble.I tried to hide my hard on and asked him to tell he how he felt. He turned around and walked a few steps and then he blushed and said “this is awesome and crazy”. He was too trying to hide his hard on but then. "I doubt if your mother works as hard as me to keep my body in shape. I don't sag where other 50 somethings do, and this is all me, no surgery, no enhancements. I just love sex and want to keep as sharp as I can. I've been single for a long time and not many men get a chance to get in my pants. You're just special. I'd love to show you how well I uh ... play. It's been quite a while, but I bet I still have skills. Is your mother that well practiced?" I said that to hurt you and scare you away.. It was in one of those nights i was sleeping with my sister that night that i woke up at 2.00am. It was my first night that I felt anything in my entire life. I still remember that night as vividly as it happened yesterday., it was just about this feeling of great hunger in my loins and I had no idea what it was. For hours i felt a hard pain in the bottom part of my stomach and the first time i noticed that I had a big erection and it actually felt good. I realised that my sis was close to me.
