Married Woman Takes Long Continuous Penetration in Swapping

The wife spends a long time having sex with her partner in another room. After penetration, they move slowly while keeping their hips pressed together, then increase the pace for deep thrusts. Even when switching to a side position midway, he does not pull out, maintaining the connection while continuing. After one climax, they do not stop and return to missionary for deeper insertion. She climaxes multiple times without him withdrawing, occasionally slowing down before thrusting deeply again in this long continuous session.
