When my brother had his first girlfriend outside the family, we had an incest sex threesome to show her how to take care of his cock! My brother’s high school girlfriend was a really sexy blonde named Jenna! She was lovely but nowhere near as beautiful and talented at taking cock as the women in our family. When I met Jenna at our family BBQ, she was the center of attention but as always, my brother’s eyes were on me. We were all drunk and horny by the time night came and all my relatives were leaving after a long day of family fucking. I was just about to look for daddy when I found my brother in his room with Jenna getting his dick sucked.
Poor thing didn’t know anything at all about how my brother likes his balls drained! I saw her struggling with his big hard cock in her mouth so I stripped down to my panties and got on my knees right next to her. Jenna was surprised but I could see my brother’s cock growing even harder just looking at my tits. Jenna watched me slurp on my brother’s cock with wide eyes but as soon as I started fingering her wet twat, that’s when things got wild! I slurped my brother deep down my throat and Jenna got competitive with me, she started fingering his asshole while I sucked him off! My brother was moaning like he was in heaven, it was only a matter of time before we were taking turns bouncing on his thick cock and fighting over his hot fucking wad of cum! Of course my brother fucked me harder, I think I might have scared her off because my brother was way more into sister fucking than she thought!
