Yes i was cooking...more for Lisa than anything else...my wife didnt suspect this was my sister.The meal went great we drunk loads of wine then played...just dance on the wii. The wife and Lisa shaking there stuff, then me and the BIL did a few numbers, but i did enjoy watching my wife and Lisa shaking there asses in my face...i could have fucked both of them that night.Everyone got more and more drunk as the evening drew on, s*s and hubby were gonna stay in the attic room, i suggested i show. ."Shall I continue?" If you kiss me like that anymore I will have an orgasm." I said."That could be a first for me," he told me as he kissed my lips softly. I reached for him I said "kiss me Matt."
