Black kissing trio: threesome with rimming and penetration on all fours

The black kissing trio is a threesome position built around rear access. The receiving person goes on all fours, on hands and knees, and the other two kneel behind their hips and take turns: rimming (oral-anal stimulation) and vaginal or anal penetration. There is no eye contact with the receiving person, and it needs agreement beforehand on roles, order and protection, because these practices mix and carry their own risks.

Anatomy and biomechanics

The receiving person kneels on the bed on hands and knees, knees hip-width apart and back level or slightly arched. The first giver kneels directly behind their hips; the second kneels beside them, slightly to the side, ready to swap. Whoever is behind uses their mouth for rimming or their hands to caress the buttocks and perineum; when the turn changes, the next person may penetrate vaginally or anally from the same kneeling position, holding the receiver's hips. The person penetrating sets the rhythm. The receiving person bears weight on wrists and knees, so the turns should leave time to rest. A clear order matters for hygiene: oral-anal and anal contact should never be followed by vaginal penetration without changing the condom or washing.

Why this position works

Some people enjoy being the centre of attention of two partners and the change of sensation between rimming and penetration. For the givers, taking turns allows pauses and a shared rhythm. There is no eye contact with the receiving person and body contact is partial, so communication has to be spoken. Sensations and comfort with anal play vary widely from person to person.

Variations of this position

Variation 1: receiver lowered onto the forearms

The same position, but the receiving person lowers their chest onto their forearms or a pillow, with hips kept high.

Only the receiver’s support changes: instead of straight arms, they rest on their forearms or hug a pillow. The hips stay up and the back arches more, which opens access from behind and takes the load off the wrists, a common complaint when turns go on for a while.

  1. The receiving person starts on hands and knees.
  2. They lower their chest onto their forearms or a pillow, keeping knees under the hips.
  3. The givers kneel behind and continue taking turns.
  4. Check the receiver’s neck and shoulders are relaxed; adjust the pillow if needed.

Variation 2: receiver at the edge of the bed, givers on the floor

The receiving person stays on all fours but at the edge of the bed, and the two givers kneel or stand on the floor behind.

The receiver’s position is the same; only the height changes. With their knees at the edge of the mattress, the givers can kneel on a cushion on the floor for rimming or stand for penetration, without kneeling on a soft bed. Swapping turns is easier because both givers have room behind.

  1. The receiving person gets on all fours with their knees at the edge of the bed.
  2. Put a cushion on the floor for whoever gives rimming to kneel on.
  3. For penetration, the next person stands behind, holding the receiver’s hips, on a non-slip floor.
  4. Check the height: if it doesn’t match, add a pillow under the receiver’s knees.

Variation 3: the waiting partner kneels in front

Instead of waiting behind, the second giver kneels in front of the receiving person to kiss and caress them while the first stays behind.

The receiver stays on all fours and one giver stays behind; only the waiting person moves, kneeling in front of the receiver’s head. This adds eye contact, kisses and caresses on the face, shoulders or chest, which the basic position lacks. The partners swap places when the turn changes.

  1. The receiving person is on hands and knees and the first giver kneels behind.
  2. The second giver kneels in front of the receiver’s head, at a comfortable height.
  3. They kiss and caress the receiver’s face, shoulders or chest while the first continues behind.
  4. When you change turns, the two givers swap places, changing condoms if there is penetration.

✓ Tips
  • Agree beforehand on roles, order and limits, and check in at every change of turn; anyone can stop at any time.
  • Use a latex barrier (dental dam) for rimming: it reduces the risk of infections such as hepatitis A, intestinal parasites or bacteria.
  • Use plenty of lubricant and a condom for anal penetration, and go slowly.
  • Change condoms between partners and never go from anus to vagina without a new condom or washing first.
  • Avoid hard thrusts from behind or pulling right out at an angle, which can bend the penis.
  • Put a pillow under the receiver's knees and take breaks to rest the wrists; lowering onto the forearms helps.

Frequently asked questions

Is rimming risky?

It can transmit infections such as hepatitis A, intestinal parasites, bacteria and some STIs. A latex barrier (dental dam), good hygiene beforehand and vaccination against hepatitis A reduce the risk.

In what order should the practices go?

Vaginal contact can come before anal, never the other way round without a new condom and washing. Keeping one order agreed in advance avoids mistakes.

Is lubricant needed?

For anal penetration, yes, and plenty of it, because the anus does not lubricate itself. It also makes vaginal penetration more comfortable.

How do we organise the turns?

Agree on who starts and with what, and announce each change out loud. The person waiting can kneel beside and caress the receiver's back or hips.
