Caught my wife's sister alone, she gets aroused and we both climax on her voluptuous buttocks

After a steamy romp with my seductive wife, I caught her enticing sister alone, her voluptuous rear begging for attention. As I approached, the sight of her in lingerie ignited a spark of desire within her. Watching her pleasure herself was a sight to behold, her every move mirroring the lust I was experiencing. I couldn't resist joining her, my throbbing member seeking refuge in her eager, hairy beaver. The moment I entered her, she moaned in ecstasy, her body trembling with each powerful thrust. As we continued our passionate encounter, her voluptuous buttocks were the perfect playground for my wild desires. The climax was explosive, both of us releasing our pent-up desire onto her ample, inviting derriere. The sight of our combined effort, a testament to our primal urges, left us both breathless and satisfied.
