Them watching Helen

Clair's full tits engulfed Joe's cock as he pumped his shaft into the offered cleavage. His head swam with the image of Helen's body arching as she orgasmed, with no idea she was being watched.

"Did you like spying on my sister? Did you like her showing us her tits without realising it?" Clair said huskily. The lust on Joe's face was it's own answer, and only a grunt came from him.

"I loved having your big cock inside of me while we could see Helen, and she had no idea. I loved sucking your shaft while we could see my sister playing with her pussy."

"I wonder what will happen tomorrow? Maybe she'll bring a man home. We can watch her fuck. Would you like that? And anything they do... You can do to me."

Clair quickly drove Joe over the edge, his cum spurting between her breasts. As it pooled between them, Joe collapsed off his wife's sticky body and exhaustion claimed them both.
