just an example. And up to you if you think OWO is safe. How did the previous cock an hour ago look like?

"If a person is infected with any of the following STDs, there is a risk they could transmit the infection via oral sex.
The most common STD transmitted via oral sex is herpes. There are two main types of herpes simplex virus (HSV): HSV type 1, which usually causes cold sores around the mouth, and HSV type 2, which generally causes sores around the genitals. If a person has HSV type 1 and they give oral sex to another person, the herpes could be transmitted to the genital area of the other person, causing genital sores. This process can also work in reverse, with HSV-2 transmitting from the genitals to the mouth of the other person during oral sex, though this is rare.
Gonorrhoea can easily be transmitted via oral sex. The infection is usually passed from infected genitals to a person's throat, but can also be passed from an infected throat to a person's genitals. The body will almost always naturally clear the throat of the bacteria that cause gonorrhoea within three months, although infections in the genital tract will usually require antibiotics to cure.
Syphilis is easily transmitted during oral sex if a person’s mouth comes into contact with an open sore or a skin rash caused by the infection.
It is possible (but thought to be not very common) for the human papillomavirus, which causes genital warts, to be transmitted through oral sex.
Chlamydia can infect the throat via oral sex, although this is thought to be uncommon. People with chlamydia may not have any symptoms and may not be aware they are infected.
The hepatitis A virus is found in human faeces, and may be passed on during anal-oral sex.
Hepatitis B is contained in sexual fluids and blood and may be transmitted during oral sex in a similar way to HIV (see below).
Hepatitis C is generally only contained in blood, and will only be transmitted if there is blood present during oral sex.
Gastrointestinal infections and parasites may be passed on during oral contact with the anus"
