The climax

Alpha huffed as he approached orgasm and squeezed the female's breasts as his entire body shuddered. His cock jerked and he fired thick streams of sperm into the female's body as she orgasmed with him. Her body tried to twist in her bonds as her pussy and ass clamped tightly over the intruding members as she felt the hot rush of the alien's seed fill her up.

After a few momments, both Alpha and Sue ceased movement and lay there panting as the act's final momments remained with them. Both robots took in the information and seemed satisfied for now.

"Both Alpha and the female have reached the limits of endurance. Recuperation will be needed." said Robot 1.

Robot 2 nodded. "Agreed. The will be transported to a secure infirmery, while Alpha can return to his quarters for recuperation." Robot 2 gaave Alpha his orders and a floating bed came in to carry Sue off. "After recuperation, we can commence testing with Beta or the hermaprodite modifications."
