In the Tucked variation of the Sinner position, the woman lies on her back with her legs bent and feet flat on the bed or other surface. She then lifts her legs off the ground and tucks them towards her chest, bringing her knees close to her shoulders. This position allows for deeper penetration and increased stimulation of the G-spot. The tighter the tuck, the more intense the pleasure can be, but it's important to find a balance that allows for comfortable penetration without slipping out. The man kneels between the woman's legs and enters her while she holds her legs in the tucked position. He can also experiment with placing his feet closer to his body and lifting his groin off the ground, which can increase the depth and mobility of penetration. This position allows for a more intimate connection and eye contact between partners, and can also be a great way to switch things up in the bedroom. Remember to communicate with your partner and find what works best for both of you.
