And this delightful tale of his young benefactor taking a gap-year between school and university was obviously fabricated - as was the notion that he would give up his work with NATO to chaperone the girl on her world travels. There certainly WAS a girl - the way his animated eyes danced and sparkled confirmed her existence but she knew. I came instantly! He started slapping my ass so hard I came again. He pulled out and came on my ass.I felt his cum cover my ass hole. Then he started working his finger in my ass. He said Your so sexy you old bitch, I want your ass riding my cock.

Suddenly he grabbed my hips and thrust it all the way in until his huge. My first load exploded inside my sister, she shrieked “fuck yes”, l gave a thrust of my cock into her hole to shoot another powerful thick creamy load into her womb, “OMG David fucking yeah!”, Theresa got another 2 full creamy loads fired deep inside her.I kept my shaft firmly wedged between my sister’s pussy lips giving little thrusts as the last of my spunk dribbled from the urethral opening at the end of my cock, after we caught our breaths l kissed Theresa hard on the mouth, she forced her.

When I reached her bed she stood up and pushed me against the wall. “What the fuck is wrong with you? I’m your best friend’s sister! Isn’t there some kind of man code against that!?” she asked. “Yes” I said. “Well then why are you fucking watching me! I should tell Aiden about this!”.
