Me and wife (Natasha) stay at the top floor of the apartment. On our floor there are only two flats. The keys to roof are with us, as the other flat was vacant until recently. The owners of that flat rented it to a Nigerian couple last month. Due to language issues they seldom interacted with anyone in the society. They went about their business quietly.
After our kids grew up, we started experimenting to spice up our relationship & explore uncharted territories. As part of our exploits we used to get intimate on the roof at late nights. This allowed us to satisfy our exhibitionist desires in the darkness of night.
During one such escapade, I observed a dark figure standing at the far end dark corner of the roof, stroking his tool. As I was about to climax, I focused on by shots. And, when I was done and looked up again, he was gone. This happened a couple of times more. So, one evening I asked Natasha, if she has observed any change in behaviour of husband from the couple next door. She responded with a negative. And asked reason for my unusual question. I narrated the incidents to her, she too was surprised and asked, if I thought it was our neighbour. I replied, I was not sure. For next few weeks I was busy with my work & we didn't get time for our roof top adventures.
Around a month later, both of us were watching an interracial porn. The bull was a black male & he was screwing the MILF vigorously and she was screaming & cumming frantically. Natasha was giving me a blowjob while I was playing with hers tits. As the action in the video intensified, I shot a big load in her face. In response she displayed her readiness for a good fuck by spreading her legs wide while laying on the sofa. High from the video, I started thrusting her deeper & deeper. It had been quite some time since we had such a vigorous sex. Exhausted I collapsed on top of her. We lay like that kissing & playing with each other's body. Later we went for a shower together & indulged in fondling. I started kneading Natasha's boobs & giving her a finger fuck. After sometime she started squeezing my fingers between her thighs & her juices started flowing from inner sides of her thighs. We kissed & had a quickie under the shower.
As we lay on our bed, I asked for her reaction to big black tool we saw in the video. She replied, she could not believe that it was natural, but the satisfaction on the woman's face caused her disbelief to be replaced by excitement. I asked if given a chance would she like to experience that BBC inside her love spot. She responded that she was not sure if she would be able to take it inside her. With a chuckle I said if that white MILF could take it, then it would be easier for a brown lady. If so then it should be quite an experience, she replied. We embraced and drifted in sleep.
