Tyga reportedly raps about sex with Kylie Jenner in his latest song.

The 'Rack City' hitmaker released the mixtape track 'Stimulated' earlier this week and it's been claimed the lyrics refer to his bedroom activities with the 18-year-old 'Keeping Up with the Kardashians' star.

He raps: ''I'm stimulated, I'm at the bank, I'm penetratin', I'm puttin' in, I'm penetratin', I'm gettin' big, she stimulated.

''They say she young, I shoulda waited, she a big girl, dog, when she stimulated.''

The 25-year-old musician previously denied he was dating the reality TV star but, after celebrating her 18th birthday earlier this month, they appear to have confirmed their relationship with a number of public displays of affection.

And it now seems he's comfortable telling the world about their intimate relationship.

The track continues: ''F**k what they talkin' about, I do what the f**k I wanna do.

''She a big girl, dog, I'm puttin' in, yeah, I'm penetratin', I'm gettin' big, yeah, I'm stimulated.

''Might take her home, gonna dinner plate it, I don't heat it up, I don't microwave it, she already hot, she sizzle, baby.

''No salt-n-pepper, she been the flava, I'ma stimulate her.''

However, it's not the first time one of Tyga's explicit raps has been linked to Kylie.

After singing about ''catching a felony'' in his single 'Pleazer' it was claimed he was referring to the fact it was illegal for him to have sex with the brunette beauty while she was still just 17 years old.

He rapped: ''T nasty, 'bout to catch a felony for it.''

However, the 'Ayo' rapper later denied the claims, insisting he was still with the mother of his son King Cairo, Blac Chyna when the song was recorded.
