My boyfriend's sisters enjoy lesbian intimacy

When my boyfriend's sister comes over, things get interesting. She loves to play with his girlfriend, and by play, I mean they get down and dirty. They're always sneaking off to the bedroom, leaving me and the boyfriend to our own devices. But he's cool with it, he knows how much they enjoy each other. They're both young and horny, and they love to explore each other's bodies in the most intimate way. They strip down to their PJs and start making out, their tongues exploring every inch of each other's skin. It's a sight to behold, and I'm not just saying that because I'm bi. They're both so into it, so passionate, and it's clear they've done this before. And let's be real, it's not like I'm missing out on the fun. I'm right there with them, watching and participating in every way I can. It's a wild, erotic ride, and I'm grateful to be along for it.
