I couldn't do anything but to feel his cock in my throat and my muscles twitching around it. That excited him even more. I gurgled, choked, and his di...k was still inside. In one stroke he took it out only to shove it whole back in. All the way.My wide gaping mouth, that I could not close even if I wanted it most in the world, were his hole for fucking. Same as it's my pussy or ass. He uses them in exactly the same way, no difference. He fucks me in my pussy, ass or throat like in his fuck. I tell you just to lay there with that dildo inside you, and I pump you with it for another 20 minutes or so...We then pull in at my marina. I grab your bag from the backseat, and tell you to walk to my boat. You are naked and argue, but I tell you to do it now, and you oblige, hastily walking to the boat. I watch as your ass swings back and forth while getting onboard. We go into the boat, and I show you around, grab you, kiss you hard, then push you to your knees, pull my dick out, and stick. I felt ashamed at the events that happened,turned off the TV & slowly went inside to apologize to my sis.I saw that the door was locked & no reply came even after knocking. After sometime I again knocked,this time she opened the door.I entering started apologizising to her.She didn’t utter a word & slowly closed the bedroom door.She came & stood near me.I was scared & started apologizing again when suddenly i felt a hand on my cock.My heartbeat raced & I said”what r u doing sis?” she said,”Just. Music was playing and an area was set aside for dancing later. It took the girls longer to change but when they did come out onto the back patio they looked stunning. They all had on Bikini’s covering the essential bits but the styles varied from thong style to casual beach wear style. Luciana was wearing a pale blue thong style which rode low in front, accentuating her pudenda. The back was just a thin piece of material dividing her rear leaving her cute arse cheeks fully on display.Neva was.
