My girlfriend Destiny, my little sister Nikki & I went on vacation to Las Vegas. When we got there, the only rooms available was with one bed. We had no choice but to take it. We went in & got everything situated & I told them that I brought ecstasy. My little sister Nikki was excited because it was her first time taking it. My girlfriend looked at me & winked before telling saying, "You should put the pills up your ass it'll hit you faster & harder. Trust me." Nikki looked at me & told us that she has never done it before because she doesn't know how. Destiny gently grabbed her by the hand & stood her up while she pulled down her pants. Nikki was shy but she went through with it & let Destiny take them off. Destiny put her on her hands and knees. "Just relax it's not going to hurt." Nikki got less tense & Destiny caressed her & said, "Arch your back like you're about to get fucked." Nikki did what she asked & it looks so hot. "Damn babe look at your sister's body. She is built to fuck. She got a fat ass & nice body. I can see why you always fantasize about her." I was in shock. Did she really expose me like that right in front of her?
Nikki looked at me and her eyes lowered as she giggled. Destiny was right though, Nikki looked perfect, even better than my girlfriend in fact. I subconsciously put my hand down my pants and didn't notice what I was doing until Destiny whispered to look at me in Nikki's ear. Nikki looked back at me and caught me with my hands down my pants looking at her ass and pussy as Destiny slapped her ass making a jiggle. "Men must have so much fun with your body. Your brother hasn't taken his eyes off of you since I put you on the bed on all fours. Look at him he is in a trance and he is jerking off while looking at you like a pervert." Destiny slapped her ass again and I woke up from my trance.
