There are many different ways that I like to give blowjobs and here are two of my favourite ways to give such pleasures:

The pivot

With the man lying down on his back, the woman positions herself perpendicular to him at a 90-degree angle – either propped up on her knees or fully laying down.
This position is incredibly arousing for him for numerous reasons. From this angle, he can easily touch, caress, and squeeze your most sensitive areas. He has a full view of every curve of your body and can make eye contact with you intermittently. He can fully relax his body and feel every subtle wave of pleasure that courses through him. Meanwhile, you can comfortably stroke his thighs and massage his perineum or anus.

The King's Chair

This is one of the best positions for receiving oral sex because it emphasises the power dynamic, which is part of what makes it so enjoyable for some men.
The man sits in a chair while the woman kneels between his legs, giving her access to his thighs, perineum, and anus. If you want to make him feel honoured and served, this is an excellent way to do so. Making eye contact in this position adds another level of heat.
