This movie is about sex but it really isn't that explicit. There is only very brief full frontal nudity. We do see a glimpseof penis and female pubes.
It starts off with some clothed spanking before the intro.
Story one has a guys thrusting hard on a girl in missionary position under the sheets. We can hear the bed springs creaking. When he's done, he just turns over and we see the woman's breasts including nipples.
A man checks and strokes his penis in his underpants. We get a glimpse of the penis.
A topless woman waits for a guy in bed.
Story two starts with a couple getting ready to have sex. She puts on green tights and takes her top off, and then puts her hand down the front of her tights and fingers herself. They then have some very quick vigourous sex with her on top.
A woman masturbates at work and outside in an alley way.
Story three starts with a man and a pregnant woman having sex in spooning position. She's wearing a top but we can see her bare pregnant belly and a glimpse of her pubes.
The guy goes to clean up where we get a glimpse of his penis, while the woman gets herself off with a vibrator. No nudity from her.
We then see the woman and her friend cuddle and caress in bed. We can see their breasts.
Story four is about a man that's addicted to his own sextapes. We don't see much nudity in this story. In once part we his butt as he undresses.
The sextapes show him having aggressive sex with a woman, but she's mostly clothed.
