(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) Your sister comes into your room wearing a new going-out top, and shyly asks for your opinion on it! You're very complimentary and she's surprised and pleased, and asks if she can show you the rest of what she bought today - but warns you that it's lingerie, so it's totally okay if you'd rather not see your sister like that! You tell her it's fine, and she begins nervously modelling the new lingerie sets she got for you, feeling shy and awkward at first but growing more relaxed and confident as you keep showering her with compliments. At first she goes back to her room to change into the next set, but after a while she says she can just get changed in your room, and you can turn away until she says it's safe... Of course, you manage to sneak quite a few glances as she gets changed, and soon you can't help but get hard over her naked body. When she spots your erection, she's stunned... but you can see that she quickly becomes aroused, as much as she tries to fight it! She tells you she thinks it's so sweet that you would get hard over her even though she's your sister, and she shyly asks to see your cock... When you get it out she seems mesmerized, and can't stop herself from asking to see you stroke it... She absentmindedly begins touching herself through her panties as she watches you jerk, so you suggest that she take her lingerie off and join you in masturbating... The two of you touch yourselves together, admiring each other's naked bodies and talking about how crazy and dirty it feels to be doing this with your sibling, before you both cum together and your sister watches in amazement as you shoot a huge load all over the floor - before immediately panicking about the crazy thing that just happened, and running out of the room making you promise not to tell anyone about it!!
