My boyfriend (25M) and I (25F) simply love to fuck quietly. You know, have sex in a kind of situation noises and moans are not "appreciated" like in his/my parents house. The risk of getting caught and the adrenaline that we both feel as we have to keep quiet is what amuse us. I just LOVE when he covers my mouth with his hand while he sidefucks me. Cum with his hand covering my mouth is VERY exciting and amazing, for me and he either.
It's common to have such "fetish"?
