Note: Tara has a penis, but she is a lady with a heartbeat and does NOT die (roughly season 6 of buffy)
Tara, a 20 year old woman, was at the Summers household and stuck with an erect penis. She just needed to cum in order to keep her sanity. For her, needing to cum without an object or Willow's body, was like having to pee during a movie at a movie theater. It was impossible, given her dick's existence was due to magic, for an erection to away on its own.Tara, given her long history of shyness, always got embarrassed when she got hard in public and her erections were visible through her dress.
Lucky for Tara, Willow had just arrived home. Tara was happy to see her lover and said "Welcome sunshine" when Willow, who had just turned 21 showed up and hugged her. Willow hugged back and felt the familiar sensation of her lover's erect genitals.
Tara told Willow "We need to go to the bedroom." Willow did nothing but smile as the two women went upstairs into the bedroom. The two women quickly got undressed using magic and were both butt-naked from head to toe within seconds.
Willow kissed Tara a bit and then teased her, with a change in the tone of her voice. "You are a hard girl". Tara smirked and winked and used body language to know what she wanted to do.
Willow said to Tara, "You want to use my butt"?? after Tara had depicted what she wanted to do with Willow. Willow then said, "You have to lick and tease my pussy first."
