That night after my parents had gone out around 8 o, clock Martin turned up, i let him in and he looked excited, he asked where the girls were, i said...they are up in their bedroom, we went up to my bedroom and i said i will show you what happens, i shouted for my sister and they came to the bedroom door in their pyjamas, i said Martin wants to see you both naked, of course, they both giggled and said no way, you first and went back to their room, i said to Martin they want to see us first are. She kissed hungrily back. She was getting aroused now. I was way ahead of her. I took off my shirt and t-shirt. I took off my shoes and socks followed by my pants. She looked down at my boxers and saw the big tent made by my 10 inch cock. I heard a small gasp escape her lips. We lie back down and continue kissing. Our hands roamed each other’s body. We were somewhat lost as to what to do but we were feeling good. I managed to remove her bra and her mannish breasts were small but her nipples. I had an older friend buy the bottle of Southern Comfort and a twelve pack of beer for us. He took another twelve pack for his trouble. Around noon, my parents said goodbye. I filled the refrigerator with beer and made sure we had plenty of ice cubes. Then I raced over to Bobby’s house to spread the news. As I ran threw Buster’s back yard, he didn’t even try to chase me. He just lazily watched me pass. As I did, I said to Buster, pounding my chest, ‘I’m the big dog now.’ I leaped the fence and. The blue veins stood out clearly on his massive shaft. He had to be nine or ten inches long, with a massive cock head that was red and drooling precum. His member was close to three inches in girth, which gave me pause. I was hoping to avoid a giant cock my first time, but Steve smiled at my wonderment. He was obviously pleased at my slight terror. He was circumcised which only made his mushroom head look that much bigger. His cock was smooth and shaven, and I could see it throb with his.
