Pretending it’s real, is the most important aspect of giving and receiving a strap-on blow job. When giving, treat the silicone cock like the beautiful and powerful tool that it is. Savor it as you start slow, playing with the head. Put your lips around it and take only the head in. Lick and tease all the way down one side of the shaft. Put it in your mouth for a minute, take it out and lick again.
