It appears that my cock was starting to stir and I had a semi. My gf noticed and commented on me getting excited because of another mans cock and then...she surprised me when she told me to touch it. I said no that I didn’t do that and she laughed and reached out and took his big cock in her hands. She looks at me kind of funny and starts to stroke the guy’s cock. I can’t believe what I’m seeing, my pretty girlfriend playing with a black cock out in the open on the beach. The guy doesn’t seem to. Then Vee went for a wee, and I took the opportunity to kiss Julie's nipples as they stuck out above the nightie."Oh, you look very sexy, darling, you're getting me really excited. Please do get one of these baby doll nighties for yourself!"She smiled. I tried to give her compliments whenever I could, although being a man, I didn't do it as often as I might have done."Pervert! Mind you, if it's going to make Gustav always be as stiff as he is at the moment, it will be a very good investment.. I can’t see your face to judge your reaction, but your strong hands release my throbbing pussy and push me onto my back. Sliding between my thighs, which spread willingly to accommodate you, your cock hovers over my pussy teasingly. Wrapping my arms around your neck, I spread soft kisses all over your whiskery face. You whisper sweet words to me, kissing my ear, telling me to put your cock inside me. I don’t need to be convinced, reaching down to guide your swollen cock to my tight pussy, just. Sitting there, staring at my sister in silence, I made a decision. This session wasn’t going to end without me moving forward. Sure, I’d taken a step back - now it was time for two steps forward.I’d waited too long and worked too hard for this bullshit. It was time for a change, and if that meant taking a different tack, that was what I’d do.“Okay Lucy,” I said. “Would you ever make out with Marcie?”Nod. Not even a moment of hesitation. It looked like my sister knew what was what, even if.
