Intermamary Intercourse, aka Titty Fucking

Inter-Mammary Intercourse

Commonly known as ‘titty fucking’, Inter-Mammary Intercourse (IMI) is a sexual act that involves a penis being rubbed between the female breasts. Squeezing together the breasts will create resistance against the penis and produce an erotic, physical sensation similar to that of penetrative sex. This activity can also naturally transition to Oral Sex.

Here we explain why IMI is attractive, how it works and a couple of guidelines about ejaculation etiquette. We’ve also come up with some helpful tips and Sex Positions for you to try!

Why the appeal?

To some extent, cultural practices and beliefs determine the degree to which breasts are viewed as sexual objects. One can infer from the Western style of dress, along with the high incidence of larger or artificial bust sizes, that the fetish of choice might likely be the breasts.

Breasts play an important role in human sexual behavior. Many women (and quite a few men) rely heavily on the breasts for stimulation during sexual arousal. For many women, having their breasts stimulated by actions such as rubbing the mound or sucking the nipple is extremely pleasurable. Using the penis as a means to caress the breasts during the course of sex can occur quite naturally, so it isn’t unreasonable to want to experiment more with that area.

The breasts and penis are stimulated by being rubbed against each other, and by the assistance of one or both sets of participants’ hands. The visual impression of IMI should also be appreciated; for some, just watching this erotic act is highly arousing.

How it Works

IMI has a couple of basic conditions that will help ensure trouble free success; the penis needs to be long enough and the breasts large enough. When both conditions are met the suggested positions will be easier to perform and physical limitations won’t hinder. A more generously endowed man has additional length to insert between the breasts and is free to experience a wider range of positions. A female with larger breasts can easily manipulate them, jiggling them up and down individually or both at the same time. If the female is flexible enough she can orally pleasure the penis as it is thrust deeply between her breasts.

Ejaculation Etiquette

The female can opt to receive ejaculate on her breasts, neck, face, or in her mouth. When the male is going to cum during the act of IMI, it is an important consideration to discuss ahead of time whether (or not) the female wants to receive ejaculate on her face or in her mouth; some women feel that Ejaculation on the face is demeaning while others do not, whilst each has their own preference regarding cumming in the mouth. When it comes to any sexual act, it’s vital that both people feel comfortable before and after the undertaking.

Tips for Overcoming Physical Constraints

When either one or both partners can’t ‘measure up’, there are still some other possibilities. A less endowed man will want to capitalize on motion, positioning and agility in order to perform the act. This holds true for the ladies as well, as a small-breasted woman can achieve the effect of IMI by actions such as ‘bouncing her body’ as she holds her breasts together.

Additionally, whatever amount of breast she can’t sandwich the penis with, she can cover the gap by joining her hands together. Going one step further and interlacing the fingers will manually stimulate the topside of penis and provide yet another interesting dimension to this action.


Ensure that the positional height for both parties is comfortable and make adjustments accordingly. For example (depending on the position), to raise height use a pillow either underneath the kneeling female’s knees, or the laying male’s buttocks. If the bed is low, the female can sit, rather than kneel; alternatively, sturdy blocks can be used under the man’s feet to raise him up. If it is preferable, incorporate a back rest, or merely bent elbows, to raise the body up. Other props such as the Liberator Ramp can also come in very handy. Finally, ensure that a bottle of lubricant is nearby.

Suggested Positions

    1. Man Sitting or Lying Back/Woman Kneeling:

    The man lies down with the upper half of his torso on the bed (or sitting back on a couch) and his buttocks positioning at the edge; the knees are bent at approximately a ninety degree angle, feet are flat on the floor and legs are spread wide. The female kneels, sits, or squats in between his legs; she surrounds his penis with her breasts and begins the motion. If her neck is flexible enough, she can bend her head to have her mouth meet the head of his penis at his deepest thrust (this can transition to ‘Game’s On’ in our Sex Positions Guide).

    2. Woman Lying Down/Man Straddling:

    The woman lies down on a bed or a couch. For added manoeuvrability, use pillows to prop her up. The man kneels on the bed and straddles her chest. As she holds her breasts together, he is free to thrust his penis in between them, and has the choice to rest his hands on her shoulders or hold onto something nearby for support. Otherwise, if his balance is good, he can lean back and use his fingers to caress her vagina. The other option is for the man is to hold the woman’s breasts together at the same time as penetrating them, leaving her hands free to wander. Again, if she doesn’t have any restrictions in her neck, she can bend it to receive his penis in her mouth. This position is also a great one to transition to oral sex with (see 'Fuck Face' in our Sex Positions guide)!

    3. Woman Lying Down/Man in Side Lunge:

    This position is accessible if the bed or couch is low enough. The woman is positioned in the same manner as position 2, but with her head at the edge of the bed/couch. The man starts by kneeling on either side of the woman’s chest and places one of his feet on the floor for more stability. The next step is to switch his weight backward and forward between the foot on the floor and the knee on the bed/couch. It is an invigorating, athletic position, making him feel dominant and confident.

    4. Man Standing/Woman Kneeling:

    The man begins by standing; the woman kneels on the floor in front of him and envelopes his penis with her breasts. For his comfort and enjoyment, find a spot where he can place his hands, either behind him or by his sides, so that he can use them as leverage or to bear down up, while he rubs his penis between the breasts. The woman can participate equally in the motion by bouncing, or she can be the only one who plays a part. This position is also a great one to transition to oral sex (see ‘Atten-hut’ in our Sex Positions guide)!

Final Thoughts

A slippery lubricant on the penis and between the breasts can assist and enhance this sexual act enabling the penis to move more freely and smoothly between the breasts (and hands).

Respect and open-mindedness will also determine the outcome. Some women may feel that IMI is degrading because of the male’s dominating positions; they may even prefer to avoid this sexual activity altogether. However, these feelings may stem from feeling vulnerable, over-powered, or inadequate. As with any concerns the answer is to communicate with your sexual partner to resolve these issues, preferably before they arise.

I enjoy giving

I enjoy giving my man a good tittie fuck. 40DDD as he skides out the top I either kiss or lick the head. I love to see the look on his face as he cums. BUT we have a deal when he gets that, I still get my awesume pleasure from him.


What if the female sits down cross legged and the male stands over her legs and breasts and he puts his penis down between her breasts while she is wearing a bra or both a low-cut shirt and bra???
I've done it with my girlfriend but she has large breasts, sometimes I sit on the top of her breasts while she gives me oral.

Titty fucking is a blast, I love having that cock so close to my mouth. Have you girls noticed how the head throbs on the upstroke!

every girl i think should notice this, due to the fact that its throbing for your mouth, and is wanting to turn you on so much but ladies look for it next time you give your man a titty fuck, it will turn ya on trust me, and if your man notices that your head is near his friends head he will give a bigger load for you to clean up with your mouth!

first time

this was what I ended up doing the first time I got my fiance (now my husband) to ejaculate; it had been a hard day, we were "drunk on fatigue" as my friend calls it (that giddy state of exhaustion), and...I don't really remember it now but I ended up teasing his penis with my boobs. they were pretty small back then but somehow I got him to cum. that was also the first time I ever tasted semen, I love it now xD

I'll do this to him sometimes as foreplay, he likes a good boobjob once in a while :3


I love doing this with my gf, its really hot, esp when she randomly stop and sucks off the top of my cock, then starts again, really good.

Tried it

I tried it I'm a little bit more than average and my ex was about a B B+ we tried it. She was not a huge fan of it becuase it was difficult with the size. But in the end she did want me to cum on her breast after a while so it worked

I've always wondered

I know inter-mammary intercourse is in fact good for us guyz... but how does the women feel about it?... i mean it cant be any different from a blowjob where the women is purely satisfying the man... but idk.. Whats the word mocking bird?...

I used to do this with my ex.

I used to do this with my ex... luckily i'm a 36DD so we had no problems doing it but I never found that it was very pleasurable for me so we changed it around a bit... I always used to lay on my back and he would straddle me so I used to push my breasts from the side and then he would use his hands to play with my nipples and sometimes he's use his mouth as well he also used to lean back a bit a play with my clit and pussy, he also used to find this more pleasurable because he found it easier to thrust between my breasts..... hope this helps x

Personally I love it!!

Personally I love it!!

my best orgasms

If I had a list of my ten all time best orgasms probably six would have come from tit fucking. The first time I ever did it was when my wife and I were dating and she sucked the head of my penis as I pushed it to and fro between her mountainous mammaries. I'm getting hard right now just thinking about my wife's DDs-yummmmmm!

It rocks!

My wife is very well endowed. The position that works best for us is with me on my back and her kneeling between my legs. This allows me to control the pressure on my cock and frees her hands up to roam. She was a 38C when we got married and I've been getting titty fucks ever since!

Slippery When Wet...

I LOVE titty fucking. My wife isn't large breasted, but she has enough to get the job done and she enjoys it as well. I usually get her pretty hot by stroking between and a helping hand between her thighs. YUM!

I enjoy titty fucking.

I enjoy titty fucking. Having my hard cock slip between her tits is so much fun and is a different feeling on my cock. I like to use some lube for this. I also enjoy rubbing her nipples with the head of my penis and watch her nipples become hard and erect. Sometimes she will start to kiss my cock each time I slide it forward and before long she will take my cock in her mouth and give me a blow job. Her tits are big enough to do this when we squeeze them together.
