Yesterday (while we had the house to ourselves - again) I seduced my wife & then I got her to sit on top of me (straddle position) for a change & she soon discovered another way to stimulate me nicely. By using her genitals, she stroked them against my scrotum & the base of my penis & I loved it a lot. We used a bit of lube on me to allow for a longer stroking session & her juices helped even more. It felt like a great massage without any hands being used. Occassionally, she rubbed my nuts a bit harder with her genitals & I'd never had her do that before - it was felt awesome & i told her to.
Sounds interesting... Gonna have to get the wife to try that out... Assuming she's gonna be back on the saddle anytime soon. So... Just gonna be me strokin the scrotum lol...
