..Once again, Lisa blushed."Well their is no boy that would kiss me and...."She stopped."And what" Bart urged her on."Well, I know I practiced with mu...m, but without having a boy kiss me before I’m not sure if they will stop and laugh if I do it wrong".Bart REALY saw a window for opportunity."Well sis, I know we have never got on well, I mean your my sister, its the law for us to not get along but if you ever need help with...'stuff'...then you can always come to me".Lisa was shocked; she was. She quickens her prodding of my backside while I fuck her mouth with just the first couple of inches of me. "Get me real wet, Lanni," I whisper. "Lick and suck me like a good little cocksucker, my pet."Before I get a little too far along and spill my seed too soon, I back down and rest the length of my truncheon on her delicious tummy. My balls hang full and loaded, down against her sexy, smooth slit, while my stiff, firm and fully extended length stretches more than halfway up her flat belly.. My hands were pressing hard her navel, boobs, my mouth was kissing her. I then removed her t-shirt with a force, started kissing all over her back. She now bent slightly and was pushing her ass into my erectile. I was pressing her boobs over the bra.She released herself from my hug, went and slept in reverse with her boobs pressing to the bed. I then went, started kissing her soft bareback and undid the bra hook. I then inserted my hands into her navel area, with great difficulty my hands. I reached back and taking my ass cheeks in both hands, spread them wide as I could."Will you fuck my ass please? I found that I really like it. I want you there. Please?" Oh baby... you know it. I loved fucking your ass too. It was so tight and hot... and so good."I felt oil dripping on my ass then his fingers pushing inside me. Pretty soon his cock, all slippery and oiled up followed. He got it fully inside me and held still, just like that night, waiting for me to get used to his size back.
