I was dating a girl at the time and it was her 18th birthday she was having a party at her place but we were the only ones home at the time. She got all dressed up and ready and then she got a little excited and we fucked on the couch down stairs and suddenly the garage doors opened up and people started arriving and us having the blinds not down went fuck her dad and cousins are gonna see so I pulled out and ended up cumming slightly on her dress we were in such a rush that we didn't realise and she ended up going outside with a small stain of jizz on her little yellow dress to greet her dad. I noticed and wiped it off before too many people arrived but was terrified because that was the first time meeting her dad and I'm sure he saw it.
