Wow.. thats a tough one... I would have to say the first night I stayed over at my missus' fathers house.. we forgot the CD's so it was going to be a NO-SEX weekend.. of course I couldnt handle this so when we got up into the loft for bed.. I blindfolded the missus' took all her clothes off, tied her to the bed with the sex rope.. and proceeded to finger her.. 2 fingers.. is all that will fit.. and using the tip of my tongue on her clit to bring her to her screaming orgasm with her dad down the stairs.. lucky there was plenty of thunder to cover up the screaming.. a little bit :O
