(This video is a bit cheaper because it's shot on my phone rather than my filming camera! The 'cumshot' in this video is imagined) Your sister seems upset and admits to you that at work today some guys were talking about how much they liked tit jobs, and then they pointed to her and said she'd never be able to give someone a tit job as her boobs are too small... Your sister asks if you think her tits really are too small, and asks if you'll look at them properly to try and see what you think! She apologises for this being so weird, but says she really just wants to know if it's possible for her to give one or not... She pulls up her shirt to let you see, and you say sorry but you're just not sure! They're kind of an in-between size; they're not tiny but they might not be quite big enough?? Your sister seems disheartened and says she wishes she could just know for sure, so she can avoid embarrassing herself in future... She gets a funny look on her face and starts to say something but quickly stops herself, and you ask her if she was considering asking to try it on you...? Your sister laughs and admits that she did think that for a second, but she knows that would be too crazy. You tell her that it's fine, and if she wants to try practicing with you she can... Your sister is so grateful and immediately pulls off her top and gets down between your legs, ready to have a go! She's surprised by how quickly you get hard, and when she starts trying she's all awkward and giggling at how hard it is. She says she thinks maybe her tits are too small after all, but you reassure her that it still feels good. She keeps trying, happy that you're encouraging her, and after a while you have to stop her, telling her that if she keeps going you'll cum! Your sister is thrilled that it was working so well, and says she's happy to carry on if you want... It would just be nice to know that she actually managed to make someone cum with her little tits! She bounces up and down enthusiastically, trapping your cock between her tits and lubing them up with her spit, until you shoot a huge load all over her chest!
