Sue, with a little help from her friend

Jen watched Ben struggle with his raging hard on. Like her he was trying to **** himself only to jerk when Ann called a number. No more no less. But like her, he was clearly on the edge.

Jen risked rubbing one of her big heavy tits with her free hand to give Ben a visual cue to take him over. It had almost the opposite effect. Jen let out a gasp as a wave of pleasure rolled over her. It didn't stop when she released her tit either, because it wobbled pleasantly for a few seconds after. It was all that Jen could do to keep her clit finger from accelerating and releasing wave after wave of pleasure across her whole body.

Ben meanwhile had closed his eyes to avoid temptation. He was still wanking his shaft as Ann reached 250, but now his breath was slowing and he was clearly thinking of church architecture, or fat men; whatever it took to slow down his response.

Jen looked across at Ben's sister Sue. She was breathing evenly and seemed nowhere near release. But her long nipples were hard and clearly achy, because every now and then Sue would raise her free hand to them, but then lower it again without touching, leaving them stiff and frustrated.

Remembering the impact that touching her own titties had just had on her, Jen wondered if maybe she could bring Sue off instead. She recalled that her friend did have particularly sensitive nipples. Maybe that was it. Maybe Sue could rub her clit all day without effect, but a few touches of those long aching nips might do it.

Jen reached out her arm. Sue was sitting fairly close anyhow. Jen brushed her finger lightly down the top of Sue's breast (an oft forgotten erogenous zone) until she pinged the nipple. Sue gasped with surprise and pleasure, so Jen did it again. Sue let out a little mew. She was suddenly fast approaching her climax. Vainly she reached out to try and do the same to Jen, but Jen calmly stroked her friend's over sensitive tit again and this time gave the nipple a hard tweak.

That did it for Sue. She grabbed frantically at her friend, pulling Jen down onto her and forcing Jen's face between her painfully aroused breasts. Jen, hot & horny herself, needed no second bidding She clamped her mouth over Sue's other nipple and continued to tweak the first. The two girl's legs interlocked and Jen ground her naked pussy into Sue's soft thigh and rubbed Sue's pussy with her thigh.

Sue, overcome with pleasure, cried out as wave after wave of desire suffused her body. In that instant Jen let go and felt her own release shoot through her body with shocking waves of orgasm. The two girls grasped each other tight, trying to hold onto some kind of stability as the earth literally seemed to move for them. Now they were kissing hard, locked together in mutual passion at the lips.

Suddenly Jen felt a warmth on her back, as if some warm liquid had spilt on her. Looking up and breaking the kiss, she realized that was exactly what had happened. Ben was sitting there, grinning all over his face, watching the two girls as great ropes of sticky white sperm jetted out of the end of his jerking cock. The next one caught both girls across the titties. The one after that caught Jen in the face and splashed Sue.

"Hey, watch what you're doing with that thing!" yelled Ben's sister.

Ben made no reply, he simply pumped his huge throbbing cannon and let off another salvo which slimed Sue from her waist almost to her chin.

"Urgh, gross!" she cried.

"Oh, I don't know," said Jen with a smile and she rubbed her slimy spunk covered tit against Sue's. Sue gave a little "Mmmm" of pleasure as the sticky girls slid together.

"I don't want to break up this little love nest..." began Ben, stroking his cock.

The girls pulled apart.

"No, I really don't want to break it up..." said Ben.

The girls slid back together.

"But," continued Ben, "there is the little matter of Sue's forfeit."
