My girlfriend allows me to sleep with my well-endowed neighbor as a birthday gift.

On my birthday, my girlfriend surprises me with my neighbor's company. She's a curvy, big-assed beauty. We share a passionate threesome, fulfilling my fantasy. She watches as we fuck, then joins in, making it a perfect gift.

In a tantalizing twist, my partner, a true gift herself, presents me with the ultimate birthday surprise. She's always been open about her bi-curiosity, and this year, she's taking it up a notch. Her stunning friend, a neighbor with a generously proportioned body, is more than willing to join our intimate playtime. The two women, with their voluptuous curves and ample assets, are eager to please. As I slip into my neighbor's embrace, my partner joins in, creating a sensual symphony of skin on skin. The atmosphere is charged with raw passion as we explore each other's bodies, our moans echoing through the house. This isn't just a one-time fling; my partner knows this is what I crave. This isn't just a threesome; it's a testament to our open relationship and her understanding of my desires. This is our unique, sexual celebration of our love.
