肛交练习让他们作为情侣轻松做爱

Caress her thigh and, using your tongue, carefully begin to stimulate her vaginal area.

The pressure caused by the penis on entering this sensitive area could cause an ********** contraction of the muscles.

When the body senses that there's no pain, the muscles will relax again.

This takes about one minute.

The active partner should wait a while and not continue thrusting until the muscle has relaxed again.
