Why the hell not...

Xavier thought to himself /I can't believe I gave into this/ he walked to lily's room and shut the door then turned to see lily patting a spot on her bed for Xavier to sit. Lily got to her knees in front of Xavier and reached for his pants, "W-wait...isn't there another you know way to teach me?" Lily raised an eyebrow, "For fuck sake your my sister I'm not too much of a fan for **** your lucky I didn't throw your ass out the window." Lily pouted then sighed and sat on Xavier's lap, being careful not to crush his boner, and ask, "Big brother, why do you hate your own lust? Is it because my body isn't good enough?" Xavier looked to his sisters eyes with a blank stare for a moment then he answers, "I-I don't think your body 'isn't good enough' your prefect the way you are....your very...cute.." Xavier blushes to his confession and lily purrs one his chest as he continues, "...and the reason I hate my lust is because I fear you and mom will think I'm weak...that I can be manipulate and addicted to lust even though it happens to me all the time I just become so angry and....I don't know I love you two too much to become a weak man." Lily gentle placed her hand on Xavier's face, "Big bro your too strong to be manipulated and it's ok to be a little addicted cause it's normal for any guy out there, it's just the way your wired in the brain, plus I love you no matter what..." She then hugs and snuggles Xavier and Xavier does the same. "So you think you can do it now?" "sighs well I don't know your a super cute girl whose willing to fuck her big brother haha nah I'll pass until I feel more comfortable." "I don't know if mr.stiff here agrees with you." Xavier then looks at the huge bulge of his cock throbbing against his sisters panties, which is becoming wet on it's own, lily giggles a little "Well what do you think? I'm feeling so horny I'm all wet so you kinda owe me now winks"
