Absolutely superb technique. Her breasts are exposed, providing visual stimulation. She’s using an advanced two handed grip providing stimulation along the shaft while she massages his frenulum with her thumbs. Her wedding ring is prominently visible. With each of his squirts, she clenches her hands around his shaft, significantly increasing how far he spurts. Last but not least, she keeps her motions very deliberate even as he orgasms, suppressing the urge to speed up in response to the urgency of his orgasm. Keeping her motions slow and controlled makes the penis feel like she’s maintaining control while it is losing it, increasing the power of the orgasm.
