I look like the typical geeky swot, long straight dirty blond hair, glasses, skinny body lacking in curves according to the large baggy clothes that I...wear to stop people looking at my assets.My best friend Dawn is the opposite, she has long dark brown hair, always had a big smile on her face, her body is very curvy with all the right curves in all the right places. She has a boyfriend who treats her like dirt, but she puts up with him because he tells her she isn't good enough for anyone else.. She was gripping her tits, pinching and pulling on her dark-brown nipples, brown eyes glazed, mouth open and her tongue licking her lips. I wondered if I could cum in her mouth like before. Her moans had turned to gasps and grunts each time I bottomed, and her left hand was now rubbing her clit. “Fuck me, I’m going to cum. Don’t stop. Fuck me hard,” she began babbling, then the babbling became incoherent, her eyes rolled back in her head, leaving only the whites showing (that was freaky),. "Sue returned his smile and crossed over to him, accepting his kiss; then she handed him a copy of the local underground rag. Ben set his attach case down and turned his eyes to the paper as Sue moved across to hang up his coat."In the classified; I circled it."Ben moved his gaze to the circled ad and read it; then he looked up at her."I thought we agreed not to try this; it's too risky."She nodded slowly."I know, but the more I read it, the more I thought it might be worth a try. Notice how. I was at her house during a family function and she was taking a nap in afternoon, I sat next to her and again more confidently than before placed my hand on her body which woke her up! I made a excuse and escaped from the situation but such situations continued. She knew what my intentions were.So finally few weeks back I took leave for few days and went to her place and was raring to have sex with her. I waited for her husband and her children to go out and when I found her alone I went.
