The Standing Cross

Whenever things get boring, try getting her in the regular standing doggy style and ask her to cross her legs.

Her buttocks will tighten and will squeeze your penis both inside and outside her vagina.

Second, it eliminates the protrusions of the hip bone that sometimes digs into your groin during profuse pounding.

The buttock muscles all bunch up to create a pad of flesh between you and her.

Try this only when sufficiently lubricated, because doing this while dry may be painful.
