What's next?

Finish (in) her!

John lifted Mel up, her petite frame hoisted easily into the air with his newfound strength. She blushed and continued kissing him as he slowly lowered her further onto his giant cock. Her legs dangled to the sides around his massive body, and John lifted her up again, this time pulling her down his shaft hard and fast. She screamed from pain and ecstasy - the meat rod stretching her out. This was the first and hardest fucking of her life. Her blonde hair swung back and forth as her body shook from orgasm after orgasm on John's cock.

Throb

John felt it. The his own orgasm coming.__

Throb

"Its time" he grinned, pulling his sister down to the base of his shaft as he started to fire his load into her. Mel screamed as several liters slammed into her virgin womb and gushed out of her pussy to drain around John's cock and pool onto the shower floor. Pump after pump, Mel's legs kicked and her body spasmed until John was done finishing inside her. Then Mel went limp. She was breathing but had passed out from the intense fucking. John turned off the shower and sat her in the corner. He admired the huge amount of cum pooled under her as more leaked out of the deflowered hole between her legs. Then he sighed and turned to see in the open doorway - with jaws hanging low - his mom, dad, and older sister Erica.
