What you wanna do is wait until she has a girly bath night. One with a deep bath, lots of bubbles and candles. Stealthily unlock the door from the other side then go prepare. Go back to your room and get naked. Make sure all your "private grooming" had been take care of recently, if not complete it now. Give yourself a quick spray and make your hair look stunning. Rub massage oil all over your body to give you a sexy sheen. Spend a little extra time rubbing it in down below so you end up at least semi erect. Set up a camera in the corner then sling the towel over your shoulder and casually stroll into the bathroom. Don't look at her, go straight to the mirror and start playing with your hair. When she says something turn around and say nonchalantly "Oh, I didn't see you there.... How fortuitous" and start casually swinging your penis round in circles. When she starts talking again turn back to the mirror and play with your hair some more, gyrating and clenching your arse to get her worked up. Steal glances at her in the mirror if you need help maintaining an erection. Start caressing yourself in an alluring manner as you turn back round. Pay her a compliment. Nothing soft like "your hairs looking good", besides, chances are it will plastered to her head with water and/or shampoo. Make it a sexual compliment, but nothing too over the top. "Your breasts are looking very pert today" "I love what you've done with your pubes" or "you have particularly neat vulva" are all acceptable. At this point your masculine power should have started to take effect on her. She will wash the bubbles out of her hair and get out of the bath then make her way over to you. Take this time to admire her movement as she rinses and stands up, continue to caress yourself and swing your penis. When she closes half the distance, slowly caress down to your penis and start pleasuring yourself to leave no doubt in her mind as to your intentions. As she approaches reach out and grab her between the legs, massaging in little circles and occasionally inserting your fingers. Kiss her gently on the neck, work your way up to her ear then back round to her lips. When your tongue enters her mouth, plunge your fingers in all the way and relish her moan. Lead her back to your room and have the best damn incestuous sex ever, sell the video and retire young. If your lucky she may like it so much you end up leaving your partners, moving to rural Alabama and settling down with your own brood of slack jawed gingers. Aaah.... That's the life...
