"Ahh, much better now."Justin watched as Christina maneuvered about his privates, shaving above his penis and all around the sides. Next she had to ge... under his balls. Without even asking permission she reached down and lifted his entire ball sack up to shave the bottom of it. She lightly tapped on his inner thigh indicating for him to spread his legs so she could get a better angle.As Justin looked at her hand holding his balls up, he finally lost the battle with his impending erection.. I was just about to leave cause I was getting a bit cold when a girl came walking down the steps to the pool, she was quite nice, brunnete, about my height, she looked older than me and was wearing a swimming costume, she had a nice shape, and good size breasts, even though they were tight under her costume. Anyway I was a bot nervous as she jumped in the pool, because I was shy and inexperienced.My first thought was I wonder if shes english, she looked it, but i wasnt sure, she started. " Derrick" Donna said in a very sleepy sounding voice. " Oh my fucking God" I thought to myself. My greatest fear was now confirmed. My sister was awake and my hand was still buried in her sweet pussy. " Dear God what have I done. How the fuck am I going to explain this to my sister? A sister that looked to her brother for protection. A sister that trusted her older brother. The guilt and shame I felt deflated my cock immediately. I didn't say a word."Derrick" my sister said again. I had to say. Angel looked up at her father as the pinkish tint began to burn in her cheeks as she spoke, “You know, most fathers would be proud that his daughter was not fooling around with other men.”Her father only shook his head and a low deep chuckle erupted from his lips. “Most fathers aren’t me.” He pulled her closer to him so she could feel his cock against her. “Fuck, I can’t believe you went out dressed like that and came home unfucked.” His hands roam down her body freely groping his own daughter.
