Then finally she inserted the butt plug, I winced and cried in pain as it entered my hole, I heard laughter from behind me. After 2 more slaps I heard...the words "stand up", to much pain I did and saw my sister hold the inflator to my buttplug, " I think we will leave this hanging out like a little tail to remind you you are mine, go on say it, say I am mistresses slut".I repeated and I felt the plug grow inside me , I began chanting ugliness and louder to please my mistress. I needed to please. No need to think about it. You will retrieve them later, no worries. Now it’s time to wear your swimsuit. Well it’s a bikini actually, but I guess that already crossed your mind. It’s a little more revealing that a usual bikini. But, after all, it’s the only thing left for you to wear so no time for regrets. Right, now you are completely naked in a public changing room on the beach, so better cover up. Take the bikini out of the envelope. The first piece is a bandeau top. Take it in your hands. She started licking my hands.I went up and down her pussy and she kept moaning. Then i started to put the tip in and she cried out. She said to put it in slowly. I did that I put it in real slow. Feeling every vein that ran through her vagina. I finally had my entire penis inside her vagina. I lifted her up and took the clothes in one hand and went to the bathroom to continue the fucking. She bled and then after getting all cleaned up we took the same position. I fucked her standing and then. He was stretching out my very tight ass. He continued pushing and sliding his cock deeper. I began pushing back towards him. When he had all of his cock buried deep in my ass; he just held it there; not moving for a while. Then he began slowly thrusting in and out... The bastard was fucking me very slowly and I loved the feeling…He moved faster and he really started fucking my ass, deep strokes.I started backing up to meet each thrust. He held my hips with his hands, as he was deep thrusting in.
