My wife and I have a wonderful sexual relationship. Which is to say we enjoy good physical sex but also a lot of fantasy play too. Melissa understands my desire to have "Variety" in my sexual life, even though I value my marriage to her very much.
My wife's family is from New England and, living in California, we don't get to see them as much as we might like. Last summer, Melissa's little sister Cindy came west to check out colleges. She is just 18 and cute as a bunny! She looks a bit like the vintage porn star Shauna Grant. You know...that innocent midwestern look? A pretty face sprinkled with freckles and a body to die for. We took her to the usual SoCal haunts...Hollywood, Disneyland and, of course, the beach.
Well, at the beach, little red haired Cindy was the star of the show! Her small but very firm tits and her fully developed rear end had every guy on the sand checking her out all day long. Me included! Melissa had told me her little sister was still a virgin but was seriously dating a fellow back home with whom she had done some "Petting." Of course this got me thinking about what kind of "Petting" she had engaged in. So, one night while we were in bed, I asked my wife about it.
"Has Cindy told you any specifics about her petting experience?" I asked.
"Oh, I knew you would get around to that." She quickly replied. "She said she had given 'Gary' a hand job while he felt up her panties."
"Did he come? I mean, where did he come?" I couldn't help but reply.
"He came on her panties." Melissa quietly told me. "He shot all of his come onto her white panties while she finished jerking him off."
By now, I was hard as a rock trying to visualize the scene in the back seat of this boy's car. My wife's little sister with her skirt pulled up and her tiny white panties just barely covering her virgin pussy stroking this young boy's cock until he spewed all of his sperm onto her underpants. I shoved my cock deep into Melissa's pussy and she continued to regale me with deliciously dirty details.
