My wife has worn many different panty colors when having sex with friends but she prefers black so that the strange cum has a deep contrast between the creamy white semen and the pantites. It's also a good indication of how large a lover's cum load is. Taking a cock doggy style does have a certain erotic appeal to my wife's senses and she concentrates on being penetrated and having her pussy filled with cum.
My wife said that the firs time she had sex with Kenny that his cum was thick and she knew it would linger in her womb for hours after he withdrew. He came deep after some passionate oggy style penetration and moaned loudly when he ejaculated. Some of his cum oozed our after a econ dot two but a lot of it stayed inside and she held it in her vagina for the rest of the night while she slept. She claimed that she dreamt of his sperm impregnating her and was not going to tell me that he had done “IT”. Of course it was only a dream but she had unprotected sex with him many times and asked him to impregnate her even though she was just taunting him to perform more passionately.
I love squirting my warm fertile cum deep inside her moist welcoming fertile pussy. I especially like it when she has her nice white panties pulled down like that.
