The former Playboy model likes to make love with her husband Hank Baskett in unusual places and currently she has been getting turned on at the thought of getting it on with the former NFL player amongst their exercise machines.

Revealing her fetish, Kendra posted on Twitter: "Drunk n just had some good sex. Mmm ... We f***ed in the gym. Have a thing for the gym right now. Idk ... I guess it counted as a round of squats (sic)"

However, the busty blonde beauty's erotic admission attracted criticism from some of her followers who tweeted her to tell her she shouldn't make such graphic posts because she is a mother.

Kendra - who has two kids, seven-year-old son Hank Jr. and two-year-old daughter Alijah - refused to apologise for her candid comments telling her prudish followers that she won't be following their rules.

In a series of tweets, she defiantly wrote: "Oops I didn't know I couldn't talk about sex #imnotsorry #humannature ... Express yourself don't repress yourself. You punish me for my fantasies, I'm breaking all the rules I didn't make ... Aw are my tweets about f***ing my hubby too graphic 4 u? Hm how can I cater to a 50yo virgins way of thinking #suckit #swallowit (sic)"

When one follower enquired as to whether her son Hank was old enough to be on the social networking site, the 'Kendra On Top' star sarcastically replied: "Oh ya. Hi Hank mama n papa just f***ed ... have a great day. (sic)"

Kendra has always been open about her adventurous sex life with Hank Baskett, with the couple previously romping in a vineyard, their kitchen, a Jacuzzi, in a car and once even on a jet ski while on vacation in Cabo, Mexico.

Kendra previously told BANG Showbiz: "The thing is we are fun people we don't trap ourselves in the bedroom we are spontaneous people and we don't take things so serious and we don't limit ourselves to our bedroom. We like to look outside the box! We venture off into different places like the kitchen and the Jacuzzi, and we've done it in the car a couple of times ... Hank and I did have sex on a jet ski in Cabo. It was awesome!"
