She moaned louder as she played with her own breasts, and squeezed the nipples as she rode on her sisters mouth. “Fuck yes Freya, just like that. Be...a good little girl and lick my pussy.” She moaned as she felt her sister lick her hard clit. She only stopped as she felt her sister try to slide her tongue into her entrance. She pulled away. “Naughty girl, who said you had permission to do that?” She hissed as she got up off her twin's face. The sight, she thought, was hot as hell. Her sisters. Stroke-stroke-stoke ... she breathed... “We’re not supposed to do this.” ... stroke-stroke-stoke ... That’s what she said but her pussy had juiced up like crazy.

Does it feel good to you, too?”“Oh, God, Eric. It feels fantastic but that’s not the point.” she whined. “You’re my son and I’m your mother..

She climbed on top of me and started riding me with a vengeance. We humped feverishly while Jessie winked and played the willing lookout for us, at least for now. It was a nice way to go for the moment, given that I had just been the aggressor, at least in theory. Then again, who was I kidding here ... my daughter had made a major.
