I came on my sister`s face

I caught my stepsis on camera when she walked into the bathroom and got naked having no idea I was there filming. Boy did she give me a hardon! She just turned 18 and we are not blood related, so why not have some fun? Especially if she offers to suck my dick for drinking all the beer I bought for my party. Eventually we didn`t stop at one blowjob and I fucked her good and came all over her face. Fucking slut, now everybody`s gonna see this video!
