Imagine that

When he mentioned that he wanted to have a threesome with another girl to his girlfriend, he imagined two horny, eager sluts performing a show for him before he spent the evening alternating between their wet holes.

He didn't imagine a horny, eager, dominant woman who edged his girlfriend while she rode him, begging to come, only to be denied repeatedly. The only mercy she'd provide is helping his trembling, weeping girlfriend off his cock and holding her hair back while she made his beloved lick his cock clean before being made to kneel behind them. 

He didn't imagine hearing what his girlfriend would sound like with her tongue buried in the woman's ass while she fucked him. A moment of guilt was erased by the way the woman's cunt tightened around his cock when she gripped his girlfriend's hair and held her, sobbing, between her cheeks when she came on his cock.

He didn't imagine how much harder he'd come in this woman when she told his girlfriend to kneel next to them and watch as they fucked. He locked eyes with his girlfriend the first time he came that night, his hands gripping the woman's hips, shouting his pleasure while he watched the tears stream down his girlfriend's cheeks and her spread cunt drip steadily on the floor.

He didn't imagine how his girlfriend would eagerly clean the woman's cunt while her tits were clamped and yanked by the chain connecting them or that he'd see his girlfriend's pussy clench when the woman declared that when she was there, only she was allowed to enjoy his come directly from the source.

He didn't imagine later, when the woman left and his edged, denied girlfriend was lapping his cock clean for the last time that night, that she would beg him to call her and set up another date the next weekend.

Imagine that.
