Custom video: step brother being mopey. You ask him why and he explains his girlfriend broke up with him ... You ask what made her want to break it off and when he answers because he cums too fast, you laugh at him and tease him. You then notice he is getting a boner talking to you in your lingerie, and at first you are annoyed and mock him, "you're hard just from a simple conversation, I can totally believe you cum too fast." However, you think you can help him practice, first with some joi as he worships your body in lingerie, as you tease him with your cleavage and titties pulled out, and then a handjob/titty fuck that you start first with an amused/annoyed attitude, saying "why are you so hard for your step sister's tits, you're so weird," "does it really feel that good that you have to moan? Keep it together, you'll never last that way," then gradually getting more sexual as you start to enjoy the seduction and anticipating a huge delicious load between your tits. At the end you try to cover up how turned on you are with more insults, saying "Well you definitely cum far too quick, step brother, but you obviously need practice so save up your cum for tomorrow, because this was unsatisfactory and I bet you'd cum even faster inside me, you weirdo."
