Her nipples were rocks on her tits. I looked at her neatly trimmed bush and saw the glistening of her juice starting to run out on her inner thigh. Sh...e wanted to fuck. She wanted me to fuck her! As she sat down in her chair at the desk she engulfed my cock in her mouth. She looked up at me and said, "You have a big fucking cock!" As she went right back down gagging on it. I grabbed her hair and began to fuck her face. She gagged slightly, but kept going. "Do you like sucking young boys cocks?". I looked hopefully across the alleyway but there was no light in her room. I left my blind half open and lay down. Half an hour passed before her light flicked on and I bounded out of bed. I could see her moving around beneath the almost closed blind and then the main light went off leaving only the bed light to cast shadows across the room. I looked at the mirror. Taped to the mirror was a piece of paper. On it was a cell phone number in large enough numerals to read from this distance. I. My cock was harder than ever. Then I undid her belt and pulled her pants down her ankles and my sexy sister stepped out of them. She stood in her black silk panties only.The silk material clung to her shapely ass and firm white thighs. Alka didi’s crotch was swollen and when I touched her front part of her panty, it was wet. I could almost see her cuntlips through her silk panties. I cupped her pussy and said” Didi ab ye choot meri hone ja rahi hai. Tere husan ka nasha mujh par chadh chuka hai.. I want to, too." "And you'd never tell mom or dad? Never?" "Of course not, Ben. I told you I'd get naked, too. You think I'd tell them about that?" True, that was true, I thought. "When will you do it again?" "I usually do it in the shower after breakfast." "Maybe we can shower together. I've never showered with a boy before. I think that'd be cool. Can we?" "You're sure you want to do this, Becky?" I asked. "Try me, Ben. Iris says it's the coolest. I'm ready," she told me and I said to come.
