It was late spring/begin-summer when i'm at home with two my friends, we are close to the door (open) of the dining room when my sister comes out of h...r room for to go to the bathroom and she had a black skirt, enough tight and at the half of thighs and with shoes like moccasins with the heel a bit tall and bare legs, after that my sister passed one of my two friends says "wow .. what a legs! .. beautiful thighs white ! ..." also if, naturally, i did a bit pretend of nothing, also i couldn't at. "Ohhhh...." he said quietly.I swirled my tongue back and forth across the front as I pulled slowly back out. I liked the shape of it in my mouth, the knobby firmness. Up and down I bobbed on it a few more times. A small burst of salty lube appeared at the tip. I licked at it, letting the string stretch from my tongue to the tip, then licked back and forth, tickling the front of his dick. Then in my mouth again. Up and down for another minute or so, enjoying the sensation of his erection easing. Jacob was tall and athletic while George was a bit bulky (but exactly how she likes them). After some convincing and offering to pay their room in our hotel (and lend them my girlfriend of course) they obliged. That night, my girlfriend was exhausted from the hiking trip. She was laying in the bed and I gave her a blindfold and told her to strip. She smiled and agreed but I could see it in her face, she just wanted me to finish as fast as I could till I went to sleep so she could do her thing. . Master..."I reach out and twist her engorged nipples, "Are you going to be my obedient slut?"Quaking she answers, "Yes! Master!" I squeeze her nipples hard again to reinforce that I am in charge and I will do as I like with her. As a reward for her enthusiasm I take the pegs off her beasts and remove her blindfold. I want her to see what is coming next. Her nipples jut out almost two centimeters from the soft surround of her tits. Deep red marks surround her nipples where the pegs had been..
